Abstract
An electric machine unit for a motorized device, said electric machine unit includes: a rotor assembly including rotor members, and a rotor shaft configured to support said rotor assembly, with said rotor assembly being capable of rotating along with said rotor shaft; and a stator assembly including stator members, with each stator member being configured to work in conjunction with a corresponding rotor member of the rotor members, and a mode selector configured to enable operation of one or more of said stator members to rotate said rotor shaft depending one or more parameters of said motorized device.
Claims10
An electric machine unit for a motorized device, said electric machine unit comprising:
- a rotor assembly comprising:
- rotor members;
- and
- a rotor shaft configured to support said rotor assembly, wherein said rotor assembly is capable of rotating along with said rotor shaft;
- and
- a stator assembly comprising:
- stator members, wherein each stator member is configured to work in conjunction with a corresponding rotor member of the rotor members;
- and
- a mode selector configured to enable operation of one or more of said stator members to rotate said rotor shaft depending one or more parameters of said motorized device, wherein
- said rotor assembly and said stator assembly are housed within a casing of said electric machine unit,
- said rotor shaft supports an intake fan and an exhaust fan, wherein said intake fan and said exhaust fan are disposed at axial ends of said rotor shaft, and
- said intake fan and said exhaust fan are enclosed by said casing,
- said casing is connected to an unit-inlet configured to provide purified air from a filter unit,
- said intake fan is configured to circulate air in the casing, and
- said exhaust fan is capable of directing air out through an unit-outlet connected to said casing.
A method of operation of an electric machine unit for a motorized device, said method comprising:
- checking, by a mode selector, a condition of a power switch of said motorized device;
- checking, by said mode selector, one or more parameters of said motorized device, depending on said power switch condition;
- determining, by said mode selector, two or more stator members from three or more stator members to be energized depending on said one or more parameters;
- and
- establishing, by said mode selector, an electrical connection of the determined two or more stator members with a power source.
