Abstract

A new and improved integral, flexible insulating member for a motor field assembly is disclosed. The insulating member includes a curved back section adapted to receive the motor pole piece through a centrally located opening. The insulating member further includes end and side sections extending from the opening and adapted to receive the motor winding such that the end and side sections interpose the winding and pole piece. The back section of the insulating member interposes the winding and motor frame. The insulator is compressed about the winding to substantially avoid vibration thereof during operation.
