Lessons In Electric Circuits -- Volume II (AC) - Chapter 13

Motor speed may be varied by putting variable resistance back into the rotor circuit. This reduces rotor current and speed. The high starting torque available at zero speed, the down shifted break down torque, is not available at high speed. See R 2 curve at 90% Ns, Figure below. Resistors R 0 R 1 R 2 R 3 increase in value from zero.
