1、The use of all metal materials makes it more wear resistant, rust proof and prolongs its service life. The copper wire has super electrical conductivity, which makes the motor output 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 speed. Two channel and three channel magnetic encoders with increased mile, suitable for any harsh environment. 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 magnetic sensitive detection motor, and outputs two channels of squares 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, baby electric shakers, paper shredders, electric doors and window and industrial drives.
