What is a geared motor?

2024-01-06

A gear motor is any motor equipped with a reduction gearbox. It is a power device that converts high-speed and low-torque motor output into low-speed and high-torque. It uses a reduction mechanism (such as gears, worm gears, etc.) to reduce the speed output by the motor and increase the torque output at the same time.


There are many types of gear motors, which can be divided into many categories:


Gear reduction motor: Reduce the speed and increase the torque through the gear set. Common gear reduction motors include parallel shaft gear reduction motors, helical gear reduction motors, planetary gear reduction motors, etc.

Worm gear reduction motor: The speed is reduced and the torque is increased through the meshing of the worm and the worm gear. Worm gear reduction motors have the characteristics of large transmission ratio, low noise, and strong self-locking properties.

Planetary reduction motor: Reduction is achieved through a combination of internal and external gears and a planetary gear mechanism. The planetary reduction motor has a compact structure and stable torque output.

Cylindrical gear reduction motor: The rotation speed is reduced and the torque is increased through the meshing of cylindrical gears. It has the characteristics of simple structure and high transmission efficiency.


Gear motors are used in applications that require high output torque and low output shaft speed, especially where space and available power are limited. These include but are not limited to the following applications:


Industrial automation: including conveying equipment, handling robots, packaging machinery, winding machines, injection molding machines, etc.

Transportation: including electric vehicles, electric bicycles, electric motorcycles, electric tricycles, etc.

Home appliances: including washing machines, range hoods, electric curtains, electric access control, etc.

Medical equipment: including surgical robots, bed adjusters, syringes, etc.

Robot field: including industrial robots, service robots, educational robots, etc.
