Gear Motor Specifications

Par de apriete

Torque is the turning force a motor and drive make. You see torque in gear motor specifications because it shows how much force gear motors can use to move or lift things. The main unit for torque is newton-meters (Nm), but sometimes you see pound-foot (lb-ft). SEW-EURODRIVE says torque in gear motors is the most force at the output shaft. This number helps you know if the gear motor can do your job, like lifting, turning, or pushing things.

Gear motors have many different torque values. Small dc gear motors for careful work can have torque as low as 0.6 Nm. Big industrial gear motors can go up to 18,000 Nm or more. The table below shows normal torque values for different gear motor models used in making things:

You need to pick a gear motor with the right torque for your load. If the torque is too low, the gear motor cannot move the load. If the torque is too high, you might waste energy and spend more money. High torque gear motors are good for heavy loads or when you need strong force at slow speed. For example, you use high torque dc gear motors in mixers, lifts, or robots that move heavy parts.

When you use dc gear motors, the torque rating changes how much current the electric motor uses. If the load is too heavy, the motor uses more current, gets hot, and can break. You should always check the torque and speed you need for your job and look at the whole motion cycle. This helps you stop overheating and keeps your gear motors working well.

Velocidad

Speed tells you how fast the gear motor’s output shaft spins. You see speed in gear motor specifications as revolutions per minute (rpm). Sometimes, you also see rotation speed or operating speed. Speed matters because it controls how fast your machine or device works.

In conveyor belts, gear motors often run from 0.8 to 40 rpm. For example, a conveyor moving at 12 inches per second with 4-inch rollers needs a gear motor speed of about 57.3 rpm. You figure out the speed you need by looking at how fast you want your machine to go and the size of the parts it moves.

The speed rating of gear motors changes how you use them. In robots, you want gear motors with higher speed ratings for quick, careful moves. In material handling, you need steady speed and high torque for lifting or moving heavy things. High torque gear motors usually spin slower, while gear motors for fast moves have higher rpm but less torque.

You should always check the speed rating in the gear motor specifications. If you use a gear motor faster than its rating, you might break the drive or electric motor. If you use it too slow, you may not get enough power for your job. Matching the speed and torque to your job gives you the best results and longest life for your gear motors.

Power

Power shows how much work the gear motor and drive can do over time. You see power in gear motor specifications as watts (W), kilowatts (kW), or horsepower (hp). Power is made by torque and speed together. The output power tells you how much energy the gear motor gives to the load.

In packaging machines, gear motors usually have power ratings from 0.18 kW (0.25 hp) up to 7.5 kW (10 hp) for small to medium machines. Some big gear motors can reach 75 kW or more, but most packaging gear motors stay under 10 kW. The table below shows normal power output ranges for packaging machines:

The power rating of a gear motor changes how much energy it uses and how much you pay to run it. The electric motor takes in power, but not all of it becomes output power because some is lost as heat and friction. Most gear motors work best at about half their rated load, where they are most efficient. If you run a motor at too high or too low a load, you waste energy and pay more.

Consejo: Pick gear motors with the right power rating and high efficiency. This saves energy and keeps your costs down.

Gear motor specifications often have performance curves that show torque, speed, and power together. These curves help you see how the gear motor works at different loads and speeds. By reading these curves, you can pick the best motores reductores for your needs, whether you want high torque for heavy loads or high speed for fast moves.

Torque, Speed, Power Relationship

Formulas

You can use simple formulas to connect torque, speed, and power in gear motors. These formulas help you understand how much work your dc motor and drive can do. The most common formula in metric units is:

T = 9550 × P / n

Where:

• T is torque in Newton-meters (Nm)

• P is output power in kilowatts (kW)

• n is speed in rpm

In imperial units, you use:

HP = T × n / 5250

Where:

• HP is output power in horsepower

• T is torque in pound-feet (lb-ft)

• n is speed in rpm

You can rearrange these formulas to solve for any value you need. For example, if you know the output power and speed, you can find the torque output. These formulas show that torque and speed work together to create output power. When you increase torque or speed, you also increase the output power of your dc motor and drive.

Engineers use these formulas to check if a dc gear motor can deliver the torque output and speed needed for your application. You can also use these formulas to compare different dc motors and drives. This helps you pick the right high torque gear motor for your job.

Gear Ratios

Gear ratio is a key part of every gear motor. It tells you how many times the input gear turns for each turn of the output gear. Gear ratio changes both the torque output and speed of your dc motor and drive. When you use a high gear ratio, you get more torque output but less speed. When you use a low gear ratio, you get more speed but less torque output.

Here is a table that shows how gear ratio affects torque output and speed:

You can see that as the gear ratio increases, the output speed drops, but the torque output rises. This is why you use high torque gear motors for heavy loads that need strong force at low rpm. For example, a conveyor belt uses a high torque dc gear motor to move heavy boxes slowly and safely.

Consejo: If you pick the wrong gear ratio, your dc motor and drive may run too fast or too slow. This can cause poor performance, overheating, or even damage. Always match the gear ratio to your load and speed needs.

Gear ratio also affects efficiency. If you use a very high gear ratio, you may lose some output power due to friction and heat. Good gear materials and lubrication help keep your dc gear motor running smoothly and maintain high performance.

You can use curvas par-velocidad to see how your dc motor and drive perform at different gear ratios. These curves help you find the best balance between high torque and speed for your application. For example, robotic arms need high speed for quick moves, but also need high torque for lifting. By adjusting the gear ratio, you can get the right torque output and speed for each task.

Reading Gear Motor Datasheets

Key Specs

When you check datasheets for gear motors, you see important numbers. These numbers help you pick the right motor. You will find torque, speed, and power ratings on performance curves. These curves show how the motor works with different loads. Torque is often on the X-axis. It tells you the force the motor shaft can use. Speed is measured in rpm and usually goes down as torque goes up. This means when the motor uses more force, it spins slower. Power is shown as a curve that peaks between the highest speed and stall torque. These ratings help you know what gear motors can do.

You also see rated torque, rated speed, and rated power near the curves. Rated speed shows how fast the motor runs with normal load. Maximum torque is the most force the gear motors can handle before breaking. Efficiency ratings tell you how well the electric motor uses energy. High efficiency means less energy is wasted and you save money. Performance curves also show how dc gear motors act at different points. This helps you match them to your needs.

Always look at these ratings before picking gear motors. They help you stop problems like overheating or breaking early.

Nameplate Info

Every electric motor has a nameplate with key information. The nameplate gives you ratings like rpm, horsepower, voltage, and full load amps. These numbers show the safe limits for the motor. Nameplates also list gear ratio, oil type, and serial numbers. Gear ratio tells you how speed and torque change from input to output. Oil specs help gear motors run smoothly.

Here is a table of common nameplate information and why it matters:

You will see different gear motors on datasheets and nameplates. Inline gear motors use spur or planetary gears for high torque and good efficiency. Right angle gear motors use worm or hypoid gears for small spaces and quiet running. Hollow shaft gear motors work well with pulleys and levers. Each type is good for different jobs, like conveyors, robots, or medical machines.

Nameplate information helps you match dc gear motors and dc motors to your job. Always use these ratings to keep your gear motors safe and working well.

Gear Motor Selection

Application Needs

When you pick a motor reductor, it must fit your job. First, think about what your machine needs to do. Every job needs different amounts of par de torsión, velocidady power. You also need to think about where the machine will be used. How often will it run? Does it need to stay very clean?

Here is a simple guide to help you choose:

1. List all requirements
   Write down what your job needs. Include things like par de torsión, velocidad, power, voltage, and how long it runs. Also, think about cost, delivery time, and service.

2. Check the environment
   Look at where you will use the gear motor. If you work with food, you need motors that are easy to clean. For outside jobs, pick motors that keep out dust and water. Hot or wet places can change how long motors last.

3. Choose the right motor type
   Decide if you need a dc or ac motor. Think about how quiet, strong, or long-lasting it should be. Some motors are better for careful moves. Others are better for heavy work.

4. Pick a gearmotor or build your own
   You can buy a ready-made gear motor. Or you can put together a motor and gearbox yourself. Ready-made gear motors save time and lower risk.

5. Calculate the required torque
   Here is how to find the par de torsión you need:

   • Find the force on your load. For example, lifting a 50 kg box means 50 kg × 9.81 m/s² = 490.5 N.

   • Multiply the force by the shaft or pulley radius. If the radius is 0.2 m, par de torsión = 490.5 N × 0.2 m = 98.1 Nm.

   • Add extra par de torsión for speeding up.

   • Add a safety factor, usually 1.5 to 2 times more. This helps the motor handle surprises and keeps it working well.

6. Check gear ratio and efficiency
   Gear ratio changes par de torsión y velocidad. A higher gear ratio gives more par de torsión but less velocidad. Make sure the gear ratio fits your job. Also, check how well the gearbox works. If it is not efficient, you need more power.

7. Think about mounting and maintenance
   Some gear motors need special ways to be put in place. Some need extra oil. Make sure you can set up and take care of the motor easily.

8. Test the motor
   After you put in the gear motor, run it as normal. Listen for noise, check for heat, and see if it works right.

Consejo: Always match the motor and gearbox ratings. If one is too weak, your gear motor may not last long.

You also need to think about special needs for your job. In food work, use motors that are easy to clean and safe. For outside jobs, use motors that keep out water, dust, and heat or cold. The table below shows how different things in the environment can change your choice:

High Torque Choices

Alta par de torsión gear motors give strong and steady power for hard jobs. You use them to move heavy things, lift objects, or do tough work. These motors are used in mining, farming, building, robots, conveyor belts, wind turbines, elevators, and escalators.

Alta par de torsión gear motors have special features:

• They give high par de torsión at low velocidad.

• They are small, so they save space.

• They work well and help save energy.

• They can move heavy loads without getting too hot.

• They make less noise and shake less, so they are good for quiet places.

You should use high par de torsión gear motors when you need strong force and steady moves. Conveyor belts use these motors to move heavy boxes. Robots use them for careful and strong moves. Wind turbines use high par de torsión motors to turn blades and get more energy.

Here are the main good and bad points of high par de torsión gear motors:

• Advantages:

  • Alta par de torsión at low velocidad

  • Strong start and fast speeding up

  • Small and saves space

  • Works well with heavy loads

  • Costs less to take care of

• Disadvantages:

  • Not good for very fast jobs

  • Not best for very careful moves

  • Needs regular care

  • Can be affected by hot or cold

Nota: Alta par de torsión gear motors are not always best for fast or very careful jobs. You need to pick the right motor for your job.

When you pick a high par de torsión gear motor, always check the par de torsión, velocidady power. Make sure the dc motor and gearbox can handle your load. Use a safety factor to stop overloading. Test the motor in your machine to see if it works well.

If you follow these steps, you can pick the right gear motor for your job. You will get good results, long life, and safe use.

When you choose a dc gear motor, you need to know what torque, speed, and power mean for your job. Torque shows how much force the dc motor can give. Speed tells you how fast the dc motor shaft turns. Power shows the work the dc motor can do. You must match torque, speed, and power to your needs. Always check the dc motor datasheet for torque and speed curves. Use this checklist before you pick a dc motor:

1. Write down your torque, speed, and power needs.

2. Check the dc motor type and shaft shape.

3. Look at the size and weight of the dc motor.

4. Test the dc motor in real work.

5. Ask experts if you see high heat or noise.

A clear understanding of torque, speed, and power helps you avoid dc motor failure and keeps your machine safe.
