Abstract

A fluid-cooled axial flux machine has a stator, a rotor disposed adjacent to the stator and a rotor shaft rotationally fixed to the rotor. The rotor shaft includes an axial coolant passage having an inlet and an opposite outlet, the rotor includes a coolant passage extending radially from the rotor shaft, and the rotor coolant passage includes an inlet in fluid communication with an outlet of theaxial coolant passage, and an outlet. The fluid-cooled axial flux motor also includes a coolant distribution header having an inlet in fluid communication with the outlet of the rotor coolant passage;a coolant collection header having an inlet in fluid communication with the outlet of the coolant distribution header; and a collection header outlet. Relative to a gravity direction, the outlet of the coolant distribution header is arranged above the stator, and the inlet of the coolant collection header is arranged below the stator.

Description

technical field [0001] The present disclosure relates to axial flux electric machines; more particularly, to fluid cooled axial flux electric machines. Background technique [0002] Electric motors convert electrical energy into mechanical energy using the principle of electromagnetic interaction between coils and magnetic fields generated by magnets. Electric motors generally consist of a stationary part called a stator and a rotating part called a rotor. The rotor is separated from the stator by a small air gap and rotates relative to the stationary stator. A rotor shaft may be coupled to the rotor to transfer rotational mechanical energy for beneficial use. [0003] Depending on the relative position of the rotor to the stator, motors can be classified as radial flux motors or axial flux motors. In a radial flux machine, the magnetic flux generated by the interaction of an energized stator and rotor extends radially with respect to the rotor shaft. In an axial flux ma...
