Title:
MOTOR DRIVING DEVICE, ELECTRIC BLOWER, ELECTRIC VACUUM CLEANER, AND HAND DRYER
Document Type and Number:
WIPO Patent Application WO/2022/085050
Kind Code:
A1
Abstract:
A motor driving device (2) comprises: an inverter (11) that converts a DC voltage into an AC voltage and that applies the converted AC voltage to a single-phase motor (12); and a voltage detector (21) that detects a motor induced voltage induced on the single-phase motor (12). In reactivation control for reactivating the single-phase motor (12) from a free running state, the absolute value of an average value of a motor applied voltage applied to the single-phase motor (12) by the inverter (11) is greater than the absolute value of an average value of a motor applied voltage when the single-phase motor (12) is activated from a stopped state.
