Abstract
A blower motor is provided for use in a machine. The motor includes a stator and a rotor rotatable about an axis. The stator includes a generally toroidal core, a first-main winding, and an auxiliary winding that is electrically out of phase with the first-main winding. The first-main winding and the auxiliary winding are both full pitch windings.
Claims20
A blower motor for use in a machine, said motor comprising:
- a stator;
- and
- a rotor rotatable about an axis,
- said stator including—
- a generally toroidal core including a plurality of arcuately spaced apart teeth,
- each pair of adjacent teeth defining a slot therebetween, and
- a first-main winding,
- said first-main winding including a plurality of first-main first coils wound about the core,
- each of said first-main first coils including a pair of arcuately spaced apart, generally axially extending first-main primary slot portions,
- each of said pairs of first-main primary slot portions defining a pair of arcuately spaced apart outermost margins of the corresponding first-main first coil,
- said first-main winding generating a plurality of first-main poles at respective arcuately spaced apart first-main pole locations,
- said motor having a slot to pole ratio of 6 to 1,
- said slots including a plurality of first-main pole-location slots,
- said first-main winding being a full pitch winding, with corresponding pairs of said first-main primary slot portions and said first-main pole locations being positioned within respective ones of the first-main pole-location slots.
