6mm Planetary Gear Motor

As an innovative gear motor manufacturer, INEED Motors designs and manufactures the smallest planetary gear motors in the market, it is known as Nano planetary DC gear motors. Our 6mm gear motor lineup includes high torque DC motors capable of delivering exceptional performance in compact spaces.

The 6mm planetary gear motor is a type of plastic gear motor that offers 6-700 times higher load capacity compared to their same-sized 6mm coreless brushed motors. If you are designing precision electronic devices, smart home products, industrial actuators, or any application that requires a DC motor with high torque low speed within strict size constraints, you can contact us now to customize these planetary DC gear motors.

There are 4 gear ratio options.

6mm planetary gear motor

These tiny DC reduction motors consist of two parts. 6mm planetary gear motor contains a 6mm diameter coreless motor and a 6mm plastic gearhead. Their gears, output shaft, and entire reducer are made of liquid crystal polymers (LCPs), also known as plastic gear motors. By combining these 4 different reduction boxes with 4 kinds of 6mm coreless motors, we can get 4 reduction motor series. The solution has 16 options.

Round Shaft

We can supply you with a round plastic shaft with diameter of 1.5mm and length of 8.05mm.

Connection Mode

The length of the wire can be customized, or various connectors can be added at the end of the wire.

Our standard planetary gear head has a D-shaped plastic output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The shaft “D” portion is 2.5 mm long. And the miniature planetary gearbox length depends on their gear ratio.

Customizable options:

Working Environment:

Typically, these motors are rated at 3.0V DC and operate at 2.1V DC to 3.6V DC. If your application needs to operate at a low starting voltage, we can set the motor starting voltage range at 0.8-1.2V DC.

The lower voltages may not be used and higher voltages may negatively affect the life span of the 6mm gear motor. The output speed range of this series of gear motors is from 6420rpm to 40rpm, the output current is 60mA, and the torque is from 5g to 200g.cm.

When the planetary gear motor is under stalling or overload, it will damage the winding and brush of the motor in a few seconds.

For these nylon transmissions, the instantaneous torque cannot exceed the upper limit of 250g.cm, we strongly recommend keeping the application loads within this limit.

The free running speed, stall torque, and stall current of the motor can reach its optimum operating condition when operating at 3.0V DC voltage.

What else are the features of these 6mm planetary gear motor?

The 6mm planetary gear motor ingeniously combines a 6mm neodymium rare-earth magnet coreless motor with a planetary gearbox. Weighing only 1.25 grams, these small gear motors offer exceptional versatility, fitting seamlessly into even the most confined spaces, including electronic locks, drones, and medical devices.

Our Nano Planetary Gearboxes feature multiple gears designed to evenly distribute loads, ensuring reliable performance under varying conditions.

Manufactured in large quantities, our 6mm motors boast superior precision. Crafted from injection-molded plastic, the Nano planetary gear motors uphold strict quality standards, guaranteeing consistent and accurate operation.

With their small size, high torque, and precise performance, these low speed high torque electric motors find applications across a wide range of industries. From medical instruments and miniature robots to consumer electronics and small appliances, the small planetary gear motors capabilities enable precise adjustments and movements, enhancing functionality in various settings.

FAQ for 6mm Planetary Gear Motor

This series of 6mm plastic planetary gear motors has four speed ratios: 5.14:1, 26.45:1, 136.02:1, and 699.02:1, indicating that they have four gear stages.

The planetary gearbox design of 6mm gear motors allows for multiple gears to distribute the load evenly, resulting in higher torque output compared to standard motors of similar size.

Its gearbox cannot be made of metal because of structural limitations. If you are looking for a 6mm metal gearbox motor, consider our 6 mm metal planetary gear motor. This series of metal planetary gear motors have stronger structural components that can handle higher torques and offer a variety of gear ratios. For more information, please contact our sales engineer immediately!
