ABSTRACT:
The invention relates to a method for controlling a brushless electric motor for operation within a specified supply voltage range, a motor control controlling the winding voltage by means of pulse width modulation (PWM) and regulating the rotational speed to a specified speed. According to the invention, the motor is so rated that the nominal rotational speed is just achieved at the nominal operating point at the nominal supply voltage and at the maximum PWM ratio.
