Welcome to the store! 1. The use of all metal materials makes it more durable, rust-proof, and prolongs its service life. The copper wire has super electrical conductivity, making the motor's output power like water and high temperature resistance. 2. The built-in encoder measures the speed to ensure that a whole set of motors have the same speed and the same transmission rate. Two-channel and three-channel magnetic encoders with increased mileage, suitable for all tough environments. 3. After the gear is ground, it is heat-treated, which has the advantages of wear resistance, long life, and low noise. The protective cover protects the encoder and prevents it from becoming dusty and unusable after being used for a period of time. 4. Each magnetic encoder contains a magnetic grid and a magnetically sensitive detection motor, and outputs two channels of square waves with a quadrature phase angle of 90°, and each motor has 16 pulse signals for each circle AB. 5. This encoder gear motor is suitable for massage chairs, electric ovens, medical equipment, electric baby shakers, paper shredders, electric doors and windows, and industrial drive systems.
