Abstract
A motor includes a protector electrically connected to the windings and positioned on the coil. A rigid bracket is sized and shaped to receive the protector. A fastening system extends over the coil, bracket and the protector and compresses the bracket against the coil. The bracket inhibits transmission of the compressive force of the fastening system to the protector and thereby shields the protector from damaging force. In another configuration, a sleeve receives the protector, and the fastening system extends only over the sleeve rather than over the protector.
