Fixed Phase, which is supplied from a constant voltage source. The other one is known as Control Phase, and it is provided with a variable voltage The connection diagram of the two AC Servo motor is shown below. The control is usually supplied from a servo amplifier. The speed and torque of the rotor are controlled by the phase difference between the control voltage and the reference phase voltage. By reversing the phase difference from leading to lagging or vice versa, the direction of the rotation of the rotor can be reversed. Two Phase AC Servo Motor As we have already seen In the previous article. Here I am going to discuss the Two Phase and Three Phase AC Servo motor. The stator of the Two Phase AC Servo Motor has the two distributed windings which are displaced from each other by 90 degrees electrical. One winding is known as a Reference or Fixed Phase, which is supplied from a constant voltage source. The other one is known as Control Phase, and it is provided with a variable voltage The connection diagram of the two Phase AC Servo motor is shown below. The control phase is usually supplied from a servo amplifier. The speed and torque of the rotor are controlled by the phase difference between the control voltage and the reference phase voltage. By reversing the phase difference from leading to lagging or vice versa, the direction of the rotation of the rotor can be reversed. The torque speed characteristic of the two phase AC servomotor is shown in the figure below. Features of A.C. Servomotor The various features of a.c. servomotor are, 1. Light in weight for quick response. 2. Robust in construction.
