Title:
CONTROL DEVICE FOR SINGLE-PHASE AC MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/077574
Kind Code:
A1
Abstract:
In the present invention, first and second magnetic sensors (24A, 24B) are disposed at positions separated from each other along the rotation direction of a rotor of a single-phase AC motor (10). In a starting process for causing the rotor in a stationary state to start in a first direction, a controller (16) drives the rotor by applying a driving voltage having a first polarity from an inverter (14) to a stator. The controller (16) detects the rotation direction of the rotor on the basis of signals detected by the first and second magnetic sensors (24A, 24B) when the rotor is in the stationary state and when the rotor is rotating. When the rotation direction of the rotor is detected as a second direction opposite to the first direction, the controller (16) inverts the first polarity of the driving voltage to a second polarity.
