ACTUATOR FOR MOTOR AND LAUNDRY MACHINE INCLUDING SAME Russian patent published in 2016 - IPC D06F37/00 

FIELD: home appliances.

SUBSTANCE: invention discloses a device for actuation of a motor and laundry machine including same. Laundry machine includes a washing tank, motor to rotate washing tank, and actuation module for actuating motor, wherein actuation module includes an inverter in order to convert DC voltage to AC voltage and output AC voltage to motor, module for determining output voltage in order to determine output voltage, applied to motor, and an inverter controller in order to control inverter so, as to actuate motor based on output voltage, wherein output voltage determination module includes a resistor, electrically connected between inverter and motor, and a comparator to compare voltage determined by means of resistor, with reference voltage and determination of output voltage based on pulse-width modulation (PWM).

EFFECT: therefore, in sensor-free laundry machine, which does not have a position sensor to read motor rotor position, it is possible to efficiently determine voltage applied to motor.
