摘要： The present invention relates to noise reduction in stepper motors during homing without compromising the torque. The proposed method is to drive the pointer (1) at rated voltage during forward direction and then continue to drive at rated voltage for small amount of time during reverse direction till the pointer (1) is accelerated [starting of pointer (1) in reverse] and then drive the motor at 10% to 30% lower voltage to reduce the noise and magnitude of bounce. This method ensures the initial torque required for the pointer (1) and also reduces the noise and bounce of pointer (1). During homing process, homing position is determined by the system by sensing the bounce back voltage using ADC (Analog to Digital Conversion) device.
