System and method for thermal management of electric machine using coolant tank

An electric machine having a thermal management system includes a stator having a stator core and a rotor having a rotor core movable relative to the stator. At least one of the stator and the rotor includes one or more windings. One or more coolant tanks encapsulate one or more windings disposed on at least one of the stator and the rotor in an interior compartment of the coolant tank. The interior compartment of the coolant tank may define a coolant flow passage through the one or more windings. The coolant tank includes a coolant inlet and a coolant outlet in fluid connection with an interior compartment of the coolant tank. Internal compartments of the one or more coolant tanks are fluidly isolated from the stator core and the rotor core. 一种具有热管理系统的电机，该电机包括具有定子芯的定子和具有转子芯、相对于定子可移动的转子。该定子和转子中的至少一个包括一个或多个绕组。一个或多个冷却剂罐将设置在该定子和转子中的至少一个上的一个或多个绕组封装在该冷却剂罐的内部隔室中。该冷却剂罐的内部隔室可以限定穿过该一个或多个绕组的冷却剂流动通路。该冷却剂罐包括与冷却剂罐的内部隔室流体连接的冷却剂入口和冷却剂出口。该一个或多个冷却剂罐的内部隔室与定子芯和转子芯流体隔离。
