Claw pole motor with a ring coil and a meandering coil

A claw-pole motor comprising:

• a first stator assembly;
• a rotor assembly orientated about a longitudinal axis and mounted for movement about the longitudinal axis relative to the first stator assembly;
• a radial air gap between the first stator assembly and the rotor assembly;
• the first stator assembly comprising a first stator portion having a plurality of first stator teeth orientated radially about the longitudinal axis and extending axially in a first direction and a second stator portion having a plurality of second stator teeth orientated radially about the longitudinal axis and extending axially in a second direction opposite to the first direction;
• the first stator portion and the second stator portion defining a first gap orientated about the longitudinal axis and extending axially between the first stator portion and the second stator portion and about the longitudinal axis;
• at least a portion of the plurality of first stator teeth extending axially in the first direction beyond at least a portion of the plurality of second stator teeth that extend axially in the second direction, to form a second gap orientated about the longitudinal axis and extending both axially and radially between the plurality of first stator teeth of the first stator portion and the plurality of second stator teeth of the second stator portion and about the longitudinal axis;
• first electromagnetic windings disposed in the first gap between the first stator portion and the second stator portion and configured to be selectively energized to exert a torque on the rotor assembly;
• second electromagnetic windings disposed in the second gap between the plurality of first stator teeth of the first stator portion and the plurality of second stator teeth of the second stator portion of the first stator assembly and configured to be selectively energized to exert a torque on the rotor assembly;
• and
• one of the first electromagnetic windings and the second electromagnetic windings extending radially inside of the other of the first electromagnetic windings and the second electromagnetic windings.
