Abstract
Official abstract text for this publication.
A motor assembly includes a motor, an inverter for changing rotational speed of the motor, a cooling fan coupled to a rotational shaft of the motor, a guide cover for guiding a gas flow generated by rotation of the cooling fan to the inverter, and at least two support members coupling the inverter to a side surface of the motor. The support members are located on both sides of a center line connecting a central axis of the motor to a center of the inverter as viewed from an axial direction of the motor. A space serving as a passage of the gas flow from the cooling fan is formed between the support members.
