Evaluate Power, Torque, and Speed

Find out the torque your project needs

Torque is the force that makes a motor turn. It helps the motor handle weight and movement. To figure out the torque, think about the weight and friction involved. For example, a conveyor belt needs enough torque to move items smoothly without stopping.

Here’s a formula to calculate torque:

τ = (I * V * E * 60) / (rpm * 2π)

Where:

• I = current

• V = voltage

• E = efficiency

• Umdrehungen pro Minute = speed

After calculating torque, check the motor’s chart. Make sure it can handle your project’s needs.

Tipp: If using stepper or servo motors, check their torque limits. These motors have specific torque ranges based on their design.

Match power to your project’s load

Power is as important as torque. It shows how well the motor handles work. Use this formula to find power:

P = I * V

This gives the motor’s electrical power. Compare it to your project’s needs. For example, servo motors need the right power for precise movements.

Keep these points in mind:

• Stall torque and current show the motor’s maximum strength.

• Free run current and speed show how it works with no load.

• Small brushed DC motors are most efficient at 30%-40%.

Anmerkung: Controlling the motor well saves energy and avoids waste.

Know how speed and torque are linked

Speed and torque affect each other. When speed goes up, torque goes down. This is important when picking a motor. For example, stepper motors are good for slow, strong tasks. Servo motors are better for fast, precise jobs.

Here’s what to remember:

• Maximum power happens at 50% of stall torque.

• Torque decreases as speed increases at constant power.

• Speed depends on voltage, calculated by:

s = E / Ke

Where E is voltage and Ke is the motor’s speed constant.

Tipp: Use motor controls to adjust speed and torque. This helps the motor work well in different situations.

By understanding these ideas, you can pick a motor that balances power, torque, and speed for your project.

Think About Size, Compatibility, and Integration

Check the motor’s size and how to mount it

Look at the motor’s size before picking one. Will it fit your project? A motor that’s too big might not fit. A small motor might lack enough power. Measure the space you have and compare it to the motor’s size.

How you mount the motor is also important. Some motors have holes or brackets for easy setup. Others may need custom mounts. Make sure the motor’s mounting style works with your design.

Tipp: Read the motor’s datasheet for size and mounting info. This avoids problems later.

Make sure it works with your power source

The motor needs steady 12V DC power to run well. Check if your power source matches the motor’s voltage and current needs. If the motor uses more current than the source can give, it might overheat or stop working.

Think about the type of power source too. Are you using batteries, an adapter, or solar power? Each has limits. For example, batteries may run out fast if the motor uses a lot of power.

Anmerkung: Use a voltage regulator to keep power steady.

Ensure it connects well with other parts

A motor must work with other parts like controllers and gears. Motor controllers, like H-bridge circuits, help control speed and direction. These are important for robots or machines needing precise moves.
