Induction vs. Reversible motors.

Filed under: AC Gearmotors — mota @ 2:26 am

World K Series Induction and Reversible motors have the same stator design with balanced windings (primary and secondary coils wound the same), and the same rotor. The only difference is the capacitor. The higher capacitance value for the Reversible generates a higher starting torque for reversing, and eliminates the negative torque area in the speed-torque curve. The higher capacitance results in higher temperatures, which is why we have a limited duty cycle.

K Series Induction motors have 4 wires, and the Reversible has 3 wires. In the Induction motor, the primary is wound differently than the secondary, and is a more efficient motor. The Reversible motor has balanced windings. Sometimes, the rotor on the reversible will incorporate a lower head height, which increases the resistance in that area, resulting in a higher starting torque.
