Abstract
The present application relates to an electric machine (1) including a rotor (13) and a stator (11). The stator has a first set of teeth and each tooth in the first set has a first winding (21) The stator also has a second set of teeth and each tooth in the second set has a second winding (41). The first winding (21) has a first winding count and the second winding (41) has a second winding count. The first and second winding counts are different from each other. The electric machine has particular application in cranking an internal combustion engine. The present application also relates to a related control apparatus (50) and a vehicle.
Claims20
An electric machine comprising a rotor and a stator, wherein the stator comprises:
- a first set of teeth, each tooth in the first set having a first winding;
- and
- a second set of teeth, each tooth in the second set having a second winding;
- wherein the first and second windings are different from each other, and wherein the first and second windings are configured to be selectively energized independently of each other, and
- wherein the stator comprises a C-shaped segment, wherein the first set of teeth are arranged in a first group and a second group within the C-shaped segment, and wherein the first and second groups are diametrically opposite each other.
A stator for an electric machine, the stator comprising:
- a first set of teeth each having a first winding;
- and
- a second set of teeth each having a second winding;
- wherein the first and second windings are different from each other, and wherein the first and second windings are configured to be selectively energized independently of each other, and
- wherein the stator comprises a C-shaped segment, wherein the first set of teeth are arranged in a first group and a second group within the C-shaped segment, and wherein the first and second groups are diametrically opposite each other.
An electric machine comprising a rotor and a stator, wherein the stator comprises:
- a first set of teeth, each tooth in the first set having a first winding;
- and
- a second set of teeth, each tooth in the second set having a second winding;
- wherein the first and second windings are different from each other, and wherein the first and second windings are configured to be selectively energized independently of each other, and
- wherein the stator comprises first and second arcuate segments, the first and second arcuate segments each comprising nine (9) teeth having an angular spacing equivalent to that of a circular stator of equivalent diameter having twenty-seven (27) teeth.
