Abstract
An AC motor is utilized to drive a closure on a vehicle. The use of the AC motor provides valuable benefits with regard to cost and size. Further, a three-phase AC motor may be utilized, and the pulses in its power supply monitored to determine an obstruction in the path of the closure. Frequency control may also be utilized to provide optimum control of the drive of the component at both start-up and stop.
