![]() This type of rotor is a special form of squirrel-cage rotor in which conductors are in the form of a drag-cup made of a non-magnetic conducting material such as copper, aluminium, or an alloy. The inertia of the rotor is further reduced using drag-cup rotor (Fig. It has high resistance in order to obtain a torque-speed characteristic as linear as possible. The rotor is usually of the squirrel cage type with small diameter and large length to keep the mechanical inertia as low as possible. This control voltage is supplied from a servo amplifier. The other winding called the control winding (or control phase) is energised by the variable control voltage which is 90 electrical degrees out of phase with respect to the voltage across the main winding. One of the windings called the main winding (also called as reference or fixed phase) is excited from the constant-voltage supply source. The stator of this motor which has a laminated structure, is wound with its two windings placed 90 electrical degrees apart in space. ![]() Similar to a normal induction motor, this motor comprises of a stator and a rotor. 1 represents the circuit diagram of AC servo motor.įig. Most of the servo motors used in servomechanisms are ac and AC servo motors are of the two-phase induction motor type. In this topic, you study AC Servo motor – Working Principle, Circuit Diagram, Construction, Characteristics & Applications.
