What is 180 Optical Encoder Motor? 180 optical encoder motor is equipped with optical encoder which enables motor to control in high-accuracy. And the unique structure makes this motor compliable with various parts. Meanwhile, due to the special materials, it produces lower noise while running and promises large output torque. Features ? Flexible installation: compliable with Makeblock platform, having flexible installation. Directly drive sprockets, gears, synchronous belts, rubber tires and tracks, etc; ? Optical encoder: control precisely with PID and PWM calculation; ? Powerful capability: compared to other motors in the same level, this encoder motor has high torque, high reduction ratio and high output rotate speed; ? Lower noise: equipped with gear case which is anti-abrasive and makes lower noise; ? Long service time: with special 45# steel output shaft, the motor can transmit great torque efficiently as well as reduce attrition and increase service life.
