Abstract
The invention rests on the idea that the information for controlling an EC-motor is taken from the adjustment or position of the control unit, which can be ascertained by means of a position indicator, such as a potentiometer, Hall indicator, etc. The current pattern for the EC-motor can thereafter, for example, be determined in a microcomputer disposed in the motor control for the control unit, without the motor having a rotor position determination.
