Method and apparatus for heat removal from electric motor winding end-turns |
摘要 |
An electric motor includes a stator having a plurality of slots. The slots have slot ends and channels formed between the slot ends. A plurality of wire windings is disposed in the slots. A plurality of winding end-turns is formed by the wire windings and is adjacent to the slot ends. The electric motor also includes a cooling tube connected to a periphery formed by the winding end-turns. The cooling tube is operable to absorb heat from the electric motor. The cooling tube can cool the winding end-turns more efficiently than traditional electric motor water jackets and/or cooling fans.
