Two-phase AC servo motors
A typical two-phase AC servo-motor has a squirrel cage rotor and a field consisting of two windings:
1. a constant-voltage (AC) main winding.
2. a control-voltage (AC) winding in quadrature (ie, 90 degrees phase shifted) with the main winding so as to produce a rotating magnetic field. Reversing phase makes the motor reverse.
An AC servo amplifier, a linear power amplifier, feeds the control winding. The electrical resistance of the rotor is made high intentionally so that the speed/torque curve is fairly linear. Two-phase servo motors are inherently high-speed, low-torque devices, heavily geared down to drive the load.
