KS06, KS09 and KS11 Series AC Synchronous Motors

Our high pole count motors naturally turn at slower speeds (72 or 60 rpm). They only need a resistor-capacitor (RC) network to operate from single-phase AC utility power. These motors provide the highest torque in an AC synchronous motor for loads that operate at 72 rpm or slower. They are available in three frame sizes.
