ROTARY DEVICE, A MOTOR AND A METHOD OF COOLING A MOTOR

摘要

A rotary device includes a stator for receiving or outputting electrical power; a rotor arranged coaxially within the stator and having one or more magnets arranged thereon, the rotor including a rotor housing having an inner wall, the magnets being arranged around the housing, and wherein the rotor also includes an axial fluid conduit for the flow of a coolant between a first end of the rotor and a second distal end of the rotor; the rotor further including one or more radial fluid conduits, the radial fluid conduits being fluidly coupled to the axial fluid conduit and arranged in use to receive coolant from or provide coolant to the axial fluid conduit, the inner wall having one or more fluid paths for the flow of coolant, thereby to cool the rotor; and a fluid impeller arranged at the first or distal end of rotor and arranged to rotate with the rotor and impart to and/or maintain rotary movement of or remove from and/or maintain rotary movement of fluid entering or leaving the rotary device.

1. A rotary device, comprising:
a stator for receiving or outputting electrical power; a rotor arranged coaxially within the stator and having one or more magnets arranged thereon, the rotor comprising a rotor housing having an inner wall, the magnets being arranged around the housing, and wherein the rotor also comprises a conduit having an axial component for the flow of a coolant between a first end of the rotor and a second distal end of the rotor; the rotor further comprising one or more radial fluid conduits, the radial fluid conduits being fluidly coupled to the conduit having an axial component and arranged in use to receive coolant from or provide coolant to the conduit having an axial component, the inner wall having one or more fluid paths for the flow of coolant, thereby to cool the rotor; at least one fluid impeller arranged at the first and/or distal end of rotor and arranged to rotate with the rotor and impart to and/or maintain rotary movement of or remove from and/or maintain rotary movement of fluid entering or leaving the rotary device.
