Abstract
A motor that is operable in response to an external power supply includes a stator core that is electrically connected to the external power supply and a rotor core positioned adjacent the stator core and rotatable about an axis in response to power being delivered to the stator core by the external power supply. A first encasement member is formed around the stator core to define a cavity and a second encasement member is formed around the rotor core and is sized such that at least a portion of the second encasement member and rotor core is disposed within the cavity. A quantity of coolant is disposed within the cavity.
Claims20
A motor operable in response to an external power supply, the motor comprising:
- a stator core electrically connected to the external power supply;
- a rotor core positioned adjacent the stator core and rotatable about an axis in response to power being delivered to the stator core by the external power supply;
- a first encasement member formed around the stator core to define a cavity;
- a second encasement member formed around the rotor core and sized such that at least a portion of the second encasement member and rotor core is disposed within the cavity;
- and
- a quantity of coolant disposed within the cavity.
A motor comprising:
- a stator core defining a cavity having a first open end and a second open end;
- a rotor core positioned at least partially within the stator core;
- a quantity of coolant, at least a portion of which is positioned between the rotor core and the stator core;
- a first encasement member coupled to the stator core to inhibit direct contact between the stator core and the coolant, the first encasement member covering the first open end;
- and
- a second encasement member coupled to the rotor core to inhibit direct contact between the rotor core and the coolant.
A motor operable in response to a flow of external power from an external power supply, the motor comprising:
- a stator core including a winding that is electrically connected to the external power supply;
- a rotor core positioned adjacent the stator core and operable in response to the flow of external power from the external power supply to rotate about an axis;
- a stator encasement member formed around the stator core to completely encase the stator core, the stator encasement member defining a cavity;
- a bearing support integrally-formed as a single part with the stator encasement member;
- a rotor encasement member formed around the rotor core to completely encase the rotor core, at least a portion of the rotor encasement member and the rotor core disposed within the cavity;
- and
- a substantially non-metallic bearing disposed in the bearing support and adapted to at least partially support the rotor core for rotation.
