| description | A motor current calculation device (9) comprises a GND wire (94), a current detecting unit (95), a decision unit (96a), and a calculation unit (96b). A motor current (Im) that has been passed through a second fan motor (81) and a drive current (Id) that has been passed through a second motor driver (82) for driving the second fan motor (81) both flow through the GND wire (94). The current detecting unit (95) detects the sum of the motor current (Im) and the drive current (Id) flowing through the GND wire (94). The decision unit (96a) determines a detection result of the current detecting unit (95) when the second fan motor (81) is not rotating as the drive current (Id). The calculation unit (96b) calculates the motor current (Im) by subtracting the drive current (Id) determined by the decision unit (96a) from a detection result of the current detecting unit (95) when the second fan motor (81) is rotating. |
