Electromotor i.e. electronic commutated motor, synchronous positioning method for e.g. electrical seat adjuster in automotive application, involves compensating position difference under given position difference by controller

摘要

The method involves connecting brushless electromotors (10, 110) over a data interface arranged in engine control units (16, 116). A position of each electromotor is determined by a position controller used in the engine control units. A governor of each motor is overlapped and activated with predetermined rotation speed of respective motors. Position difference of the motors is computed as an input of a respective position controller. The position difference is compensated under a given position difference by the controller as the default rotation speed of one of the motors is changed.
