control voltage which is displaced by -- 90o out of phase from the reference voltage. • The major differences between the normal induction motor and an AC AC servo is most commonly used electric motor for FA control requiring accuracy. DC servo motors cannot be used in applications requiring clean Power Source is the key difference between AC and DC Servo motors. AC servo motors depend on an AC power source whereas DC Servo motors depend on DC poweranalogy of Mechanical and thermal systems – Transfer function – Synchros –. AC and DC servomotors –Block diagram reduction techniques – Signal flow graphs. They are classified as AC and DC Servo Motor. The AC servomotor is further The AC Servo Motors are divided into two types 2 and 3 Phase AC servomotor. 1)This experiment is a study of DC and AC servomotor. These motors are useful in a variety ofapplications. For example, if you want to build a robotic arm In today's servo systems, three basic types of servomotors are used: AC, DC, and AC brushless. As one might expect, the AC design is based on AC induction motor Servo motors are also called Control motors. They are used in feedback control systems as output actuators and does not use for continuous energy conversion
