Simple motor- micro motor
What is micro motor? Micro motor is a motor, after power, the rotation speed at least reach hundreds of high speed r / min, and in this case, the motor torque is very small and it can not move heavy goods, then it need to slow down the speed, Micro DC motor with gear that the whole is called micro gear DC motor. This motor can speed down to tens - a few tenths of r / min and can be adjusted freely. To give an popular example, electric razor, only needs micro-motor, it precisely requires fast speed and small torque. But for some lifting equipment such as projectors automatic lifting device, it requires small rotation and big torque, so it must choose the gear brushless motor. Therefore, micro-motor is a kind of simple lightweight class motor among motors.
