AC Induction Motors

AC Induction Motors provide high reliability and high efficiency, with unparalleled performance per unit volume and weight. The engineering reference data delineated nominal motor performance for our seven frame size motors, over a range of operational frequencies. With advances in motor winding configurations, control electronics, and drive techniques, high performance AC motors are no longer limited to 400 Hz operation. Induction motors are used in many applications where less reliable Brush Type DC motors or high complexity Brushless Motors were previously used.
