With the advancement of motor control and construction, the operational difference between servo motors and stepper motors has become minimal. Theoretically, a servo motor can move to an infinitely small fraction of a rotational degree, whereas a stepper motor is limited by the number of individual stator windings that create each step. Practically, these limitations do not exist.In general, a servo motor is just a part of a servo system. The system consists of a motor, a drive and a feedback device.The drive, or amplifier, takes the incoming ac power and rectifies it to supply a dc voltage to the drive circuitry. The drive can be a simple rectifier with power relays…Full Story
