Abstract
An electric motor includes a back yoke provided as an outermost layer of a stator, a stator core including a first teeth portion protruding from the back yoke toward the center portion of the stator and a second teeth portion protruding upwards from the external upper surface of the first teeth portion, a coil winding around the stator core, and a rotor in which a permanent magnet is mounted on the rotor core and which rotates through a magnetic interaction with the stator.
Claims15
An electric motor comprising:
- a back yoke provided as an outermost layer of a stator;
- a stator core including at least two teeth portions including:
- a first teeth portion protruding from the back yoke toward a center portion of the stator;
- and
- a second teeth portion protruding upwards from an external upper surface of the first teeth portion;
- a coil winding around the stator core;
- and
- a rotor, wherein a permanent magnet is mounted on a rotor core of the rotor and wherein the rotor rotates through a magnetic interaction with the stator,
- wherein the at least two teeth portions of the stator core further includes a third teeth portion protruding upwards from an internal upper surface of the first teeth portion, and
- wherein the coil includes:
- a first coil portion winding around the first teeth portion;
- a second coil portion winding around the second teeth portion, and
- a third coil portion winding around the third teeth portion, and
- wherein the first and second coil portions are connected to each other at end portions thereof and the first and third coil portions are connected to each other at end portions thereof so that a single coil winding around the stator core is formed.
