Less torque will be developed above or below 10% slip. The rotor will see 200% - 10% slip with respect to the counter-rotating magnetic field phasor. Little torque (see torque vs slip curve) other than a double frequency ripple is developed from the counter-rotating phasor. Thus, the single-phase coil will develop torque, once the rotor is started.

Sep 01, 1996· Horsepower--In general, if the roll threading head can fit on the machine, there's enough horsepower. Where it is still questionable, a formula has been developed that can provide a minimum horsepower estimate.
