For application in motors, potentiometers need a long service life or high linearity. Since most potentiometers in motors are used to adjust speed and resistance distribution, the potentiometer is related to motor balance. Besides, potentiometers also need good voltage tolerance performance because of high input current into motors.
We use high quality carbon film slurry to ensure high linearity and wear resistance of potentiometers. Linearity error of potentiometer can be controlled within 2% and the service life is extremely long.
