Abstract:
A drive system for a motor has a switching network for supplying three phases of power to a motor, and a control for the switching network. The control is programmed to provide a commutation with a positive offset, ahead of a current position, when driving in opposition to a load, and to use one of a zero or negative offset when the control drives the motor complementary to the load force. A method and system are also disclosed and claimed.
