  • Electric machine with modular stator coils and cooling tubes
    Patent number: 9712011
    Abstract: A stator of an electrical machine includes a stator core having a plurality of stator teeth and stator slots, and a stator winding having a plurality of stator coils. The width of each stator coil is one stator slot pitch, and the stator teeth are shaped to allow each stator coil to be installed by pushing the stator coil to surround one of the stator teeth. The stator coils include tubular cooling channels for conducting cooling liquid in the stator slots.

  • STATOR OF AN ELECTRICAL MACHINE AND AN ELECTRICAL MACHINE
    Publication number: 20130285487
    Abstract: A stator of an electrical machine that is straightforward to assemble and for which an efficient liquid cooling can be arranged includes a stator core (801) having a plurality of stator teeth and stator slots, and a stator winding having a plurality of stator coils (803). The width of each stator coil is one stator slot pitch, and the stator teeth are shaped to allow each stator coil to be installed by pushing the stator coil to surround one of the stator teeth. The stator coils include tubular cooling channels (804) for conducting cooling liquid in the stator slots. The stator winding is designed by taking into account the aspects related to the liquid cooling, and it has been noticed that a stator winding structure which is advantageous for arranging the liquid cooling has satisfactory electrical and magnetic properties too.
