Patent ID: 7562542

Claim:
A drum type washer comprising: a tub having a tub opening and brackets on the tub to support bearings; a drum provided within the tub to have a washing chamber inside; a door provided over the tub to open/close the tub opening; a motor rotating the drum, the motor comprising; a rotor provided to an outside of the motor to make a rotation, the rotor comprising: a rotor frame made of a steel plate in one body; a multitude of magnets attached to an inner circumference of the rotor frame; and a position decision magnet coupled to one side of the rotor frame; a stator provided within the rotor to receive a current, the stator comprising: a sensing unit having a speed detection sensor detecting a plurality of the magnets and a position detection sensor detecting the position decision magnet; a washing shaft coupled to a front center of the drum to be connected to the motor; and an assist shaft coupled to a rear center of the drum; and wherein the sensing unit comprising: a sensor housing mounted to an insulator of the stator; a sensor loading part provided at the sensor housing wherein a speed detector sensor extends into a gap between an inner stator teeth and the insulator; wherein the speed detection sensor detects an electrode variation of the magnets provided to the inner circumference of the rotor; a sensor housing extension piece extending from the sensor housing; and the position detection sensor extending into a gap between an inner circumference of the rotor and an outer circumference of the stator.
