Patent ID: 6940237

Claim:
A washing machine, comprising: a washing drum; a drive motor for operating said washing drum and having a rotor and a stator; a processor-controlled inverter connected to and controlling said drive motor, said drive motor commutating brushlessly by way of said processor-controlled inverter; an actuator disc connected non-rotatably to said rotor of said motor, said actuator disc having an incremental sensor with mutually spaced actuators disposed along a path of rotary movement; a pulse sender fixed with respect to the washing machine tub, and in a course of said actuators on said actuator disc moving past said pulse sender trigger incremental counting pulses; an incremental counter counting the incremental counting pulses for determining information about an instantaneous angular position of said rotor relative to said stator; and a processor connected to and controlling said inverter and further connected to said incremental counter, said processor receiving the information about the instantaneous angular position.
