Title:
ELECTRICALLY POWERED DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/067811
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrically powered device that can stably control a motor in a sensorless-driving scheme. An electrically powered device of the present invention comprises: a motor that has a rotor and a stator which has a winding; an induced voltage detection means that detects an induced voltage generated in the winding; and a motor control means that controls the motor on the basis of the induced voltage. The induced voltage detection means includes: a digital signal outputting means that outputs a digital signal that corresponds to the induced voltage to the motor control means; and an analog signal outputting means that outputs an analog signal that corresponds to the induced voltage to the motor control means.
