ELECTRIC MOTOR
A technique that can prevent an increase in size of an electric motor is provided. According to an embodiment of the present disclosure, an electric motor 400 includes a rotor 10, a stator 20, a through-hole 14A, and an inflow path (such as a gap 36 or a through-hole 38). The rotor 10 is configured...

Zusammenfassung: | A technique that can prevent an increase in size of an electric motor is provided. According to an embodiment of the present disclosure, an electric motor 400 includes a rotor 10, a stator 20, a through-hole 14A, and an inflow path (such as a gap 36 or a through-hole 38). The rotor 10 is configured to be rotatable about a rotation axis AX, and a turbofan 300 is fixed to the rotor 10. The stator 20 is disposed inward of the rotor 10 and includes claw pole stator units 21. Each of the claw pole stator units 21 includes a winding 212 that is wound in an annular shape around the rotation axis AX and a stator core 211 that surrounds the winding 212. The through-hole 14A is provided in one end portion of the rotor 10 so as to penetrate from the inside to the outside of the rotor 10. The stator 20 is provided in the inside and the turbofan 300 is fixed to the outside of the rotor 10. The inflow path is configured to cause a surrounding fluid to flow into the inside of a stator unit 21C provided at one other end portion opposite to the one end portion in an axial direction. |
