Electrical power steering device for vehicle, has connection part comprising conductive plates with sensor plate, whose end is connected with sensor, such that sensor signal is supplied from sensor to microprocessor through sensor plate

摘要

The device has a control unit (18) controlling an operation of an electric motor (1), and comprising a connection part between a heat sink and a rotor shaft (2), where the connection part has conductive plates. A micro computer (30) produces a drift signal to control the operation of semiconductor switching units (Q1 - Q6). The plates comprise a conductive sensor plate (22c), where an end of the plate is connected with a rotational position sensor, such that position sensor signal is supplied from the sensor to the microcomputer through the sensor plate.
