A cooling structure includes a fan that suctions gas through an inlet and sends gas, a flow path that connects the inlet and the fan to each other, a foreign matter entry suppression member that suppresses entry of a foreign matter into the flow path through the inlet, and a vibration suppression member set between the foreign matter entry suppression member and the fan and provided to suppress vibration of a rod-like foreign matter caused by rotation of a blade of the fan. The foreign matter entry suppression member includes a plurality of opening portions for suctioning gas into the flow path. The vibration suppression member is constructed to be provided with a plurality of opening portions while it is set in the flow path.

Cooling structure

A brushless motor includes a first motor unit and a second motor unit having a common rotary shaft and coupled to each other in an axial direction in which the rotary shaft extends, and two resolvers configured to respectively detect a rotation angle of the first motor unit and a rotation angle of the second motor unit. The two resolvers are arranged in the first motor unit.

Brushless motor

An embedded magnet motor includes a stator core, a plurality of permanent magnets each having a rectangular cross section, and a rotor core. The stator core and the rotor core define a first air gap being positioned at an intermediate portion of the rotor core, a second air gap being positioned at a first portion corresponding to a first axis of the rotor core, and a third air gap being positioned at a second portion corresponding to a second axis of the rotor core. Because a diameter of the intermediate portion being positioned between the first portion and the second portion of the rotor core is set smaller than a diameter of the first portion and than a diameter of the second portion, the first air gap is set greater than the second air gap and than the third air gap.
