Document Type and Number:
Japanese Patent JP5893127
Kind Code:
B2
Abstract:
An air conditioner includes: an outdoor fan 10 provided in an outdoor unit 3; a permanent magnet synchronous motor 7 that drives the outdoor fan 10; an inverter 14 that uses a DC power source 5 as a power source and applies a voltage to the permanent magnet synchronous motor 7; an inverter control means 19 that controls the output voltage of the inverter 14; and a shunt resist 15 connected between the DC power source 5 and the inverter 14. If the outdoor fan 10 is rotating due to an external force while the inverter 14 is stopped, the inverter control means 19 causes the inverter 14 to operate using a brake sequence 22 that brakes the rotation of the outdoor fan 10, and then causes the inverter 14 to operate using a drive sequence 23 that power-drives the outdoor fan 10.
