摘要:An electric motor comprising: a stator comprising a plurality of circumferentially distributed drive elements for causing an electromagnetic driving force to be applied to a rotor of the electric motor in use, wherein each drive element comprises a wire extending around a metal core to define a plurality of coils for magnetizing the metal core when current flows in the coils, and wherein at least one space exists between the metal core of each respective drive element and the coils around it; and cooling means for transferring heat away from the drive elements; wherein each said drive element further comprises a heat conductor comprising a plurality of mutually electrically isolated metallic elements located in the or each respective space between the metal core thereof and the coils around it, for transferring heat from the coils to the cooling means.
