Electric motor i.e. stepper motor, for automobile field, has insulating support to support coils of stator and with two parts assembled on both sides of magnetic circuit, where one of parts is secured and integrally formed with connector

摘要

The motor has a rotor mounted on bearings and rotating relative to a stator and a case. The stator has coils (28) supported by an insulating support, and a magnetic circuit (20) surrounding the rotor. Each coil surrounds a corresponding radial arm (24) of the circuit. A connector (30) interconnects the coils with an external power supply, and has contacts made of stamped sheet metal. The support has two parts (32a, 32b) assembled on both sides of the circuit, where one of the parts is secured and integrally formed with the connector. The case and the parts are made of plastic material.
