Method and device for multi-frequency actuation of a DC motor

摘要

The method involves synchronously operating a direct current (DC) motor e.g. pump motor (160), by a pulse/pulse pause control. The motor is additionally operated by another pulse/pulse pause control, which overlies the former control and has a lower frequency than the former pulse/pulse pause control. The controlling of the motor is carried out by the latter control dependent on detection of request for increasing or decreasing rotation of the motor. An independent claim is also included for a device for controlling and/or regulating a direct current motor.
