MOTOR CURRENT CALCULATION DEVICE AND AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a motor current calculation device that easily finds a motor current, and to provide an air conditioner with the same.

SOLUTION: The motor current calculation device 9 includes: GND wiring 94; a current detection part 95; a determination part 96a; and an operation part 96b. The motor current Im applied to a second fan motor 81 and a drive current Id applied to a second motor driver 82 for driving the second fan motor 81 are made to flow to the GND wiring 94. The current detection part 95 detects the sum of the motor current Im flowing on the GND wiring 94 and the drive current Id. The determination part 96a determines the detection results of the current detection part 95 at a time when the second fan motor 81 is not rotated as the drive current Id. The operation part 96b calculates the motor current Im by subtracting the drive current Id which is determined by the determination part 96a from the detection results of the current detection part 95 at a time when the second fan motor 81 is rotated.
