Document Type and Number:
WIPO Patent Application WO/2021/199586
Kind Code:
A1
Abstract:
Provided is a motor structure that makes it possible to improve layout flexibility with respect to a motor structure in which a controller and an inverter are disposed. A motor structure (M) comprises: a motor case (35); a stator (52) that is fixedly supported by the motor case (35) and that is configured as a winding coil; a rotor (50) that is rotatably supported by the motor case (35) and in which a magnet (51), which opposes the stator (52), is arranged; and an inverter (22) that drives a motor unit (23) configured from the stator (52) and the rotor (50), and a controller (21) that controls the inverter (22), the inverter (22) and the controller (21) being disposed in the motor case (35). The motor structure (M) is characterized in that: the controller (21) is arranged on a controller substrate (42); the inverter (22) is arranged on an inverter substrate (41); the inverter substrate (41) is mounted in close contact with an internal surface, which is the inner surface of the motor case (35); and the controller substrate (42) is arranged spaced apart from the inverter substrate (41) in the direction of a shaft (60) of the motor unit (23).
