Title:
MOTOR DRIVING DEVICE AND WASHING MACHINE OR WASHING AND DRYING MACHINE USING THE SAME
Document Type and Number:
Japanese Patent JP2017063952
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor driving device which includes a cheap and highly accurate vibration detection method, in the motor driving device used for a washing machine and the like for detecting vibration of a washing and dewatering tub by an acceleration sensor.SOLUTION: A motor driving device includes power sources 1, 2, a motor 4 driven by a circuit connected to the power sources and for driving a washing and dewatering tub 5, rotor position detection means 4a for detecting a rotation state of the washing and dewatering tub 5, and a control part 6, and it detects vibration amplitude of the washing and dewatering tub 5 by calculation by output of an acceleration sensor 7 mounted on the washing and dewatering tub 5. The control part 6 enables vibration detection which is cheap and which is hardly affected by noise by executing communication for switching a sampling frequency of the acceleration sensor 7 into a plurality of values according to the rotational frequency of the washing and dewatering tub 5.SELECTED DRAWING: Figure 1
