Title:
PERMANENT MAGNET SYNCHRONOUS MOTOR CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2012/089466
Kind Code:
A3
Abstract:
The present invention relates to a control circuit (1) that controls the permanent magnet synchronous motor (M) used in driving the drum in washing machines, that comprises a converter (2) that converts AC mains voltage to DC voltage, a three-phase inverter (3) that inverts the direct current received from the converter (2) to three phase current (la, lb, lc), a speed and position estimator (4) that detects the data relating to position and speed of rotor by means of voltage sensors during start up and operation of the motor (M) and a microcontroller (5) that provides control of the motor (M) by sending sinusoidal switching signals to the three-phase inverter (3) with the signals received from the speed and position estimator (4).
