What is micro geared motor？

Micro geared motor also known as micro reducer motor, it is a combination of reducer and motor. Micro geared motor is used to reduce the speed and increase the torque to meet the needs of mechanical equipment. And this combination can also be called gear reducer or gear reducer motor. Different gear ratio can provide different speed and torque, which greatly improve the utilization of DC motors in the automation industry. Generally speaking, miniature gear motor is assembled by a professional gear motor manufacture. 

How does a miniature gear motor work?

Reducer, gearbox and gear play a central role in the work of miniature gear motor motor. These functions transfer the force of the DC micro motor from the input to the output. Therefore, the reducer plays the role of speed and torque converter.

In most applications, the reducer reduces the speed of the motor, and at the same time, it transmits much more torque than the motor itself can provide. This determines whether the reducer motor is suitable for light, medium and heavy loads, and whether it is suitable for short or long term operation with loads. 

According to the reducer is to increase or reduce the speed of the micro DC motor (known as the input speed), the concept of gear ratio or transmission ratio is introduced, which is a kind of transmission ratio, refers to the ratio of the instantaneous input speed and output speed in the deceleration mechanism, expressed with the symbol "I".  

Gear ratio calculation formula: Gear ratio = input speed ÷ output speed, if the input speed is 1500r/min and the output speed is 25r/min, then the gear ratio is: I =60:1  

Another important variable for a reduction motor is the maximum torque at the output. The force of the reducer motor and the load capacity of the reducer motor are measured. 

Geared motor torque formula: Torque (N· M)= Motor rated power (W)/(2 * π * speed /60).

When the motor power is fixed, the lower the speed, the bigger torque.
