Abstract (en)
[origin: EP3954903A1] Included are: a blower motor unit (240) that includes a blade (230) and a single-phase motor (220) having the blade (230) attached to its rotor (221); a substrate (210) mounted with a motor controller that controls driving of the single-phase motor (220) and includes an inverter that outputs alternating-current power to the single-phase motor (220); and a housing where the blower motor unit (240) and the substrate (210) are disposed. The substrate (210) is disposed in a position where the substrate (210) is cooled down directly or indirectly by wind that the blower motor unit (240) generates.
