Electric motor for an electric vehicle |
摘要 |
It is an object of the present invention to provide an electric motor for an electric vehicle with an improved cooling capacity by causing coils wound around a stator to serve as a tubular heat pipe type heat transfer device. An electric motor for an electric vehicle includes a stator 11, coils 12 wound around at least the stator, and a rotor 13 being rotated by an induction field developed around the coils 12. In one embodiment of the invention the coils 12 are formed of a tubular container 121 which is filled with a working fluid which vibrates in an axial direction of a tube by nuclear boiling generated at a high temperature portion of the coils 12. The coils themselves are arranged as a non-looped tubular heat pipe type heat transfer device.
