Abstract
One embodiment relates to a stator unit and a motor comprising same, the stator unit comprising: a stator core; a coil wound around the stator core; and an insulator disposed between the stator core and the coil, wherein the stator core comprises a support part, and a coil winding part disposed on both side surfaces of the support part so as to protrude therefrom, wherein the support part and the coil winding part are disposed so as to form a cross shape. Accordingly, a coil space factor may be increased by using the cross-shaped stator core.
Claims15
A motor comprising:
- a shaft;
- a rotor including a hole into which the shaft is inserted;
- and
- a stator disposed outside the rotor,
- wherein the stator is formed by disposing a plurality of stator units along a circumferential direction,
- the stator unit includes a stator core, a coil wound around the stator core, and an insulator disposed between the stator core and the coil,
- the stator core includes a support part disposed in a radial direction with respect to a center C and a coil winding part disposed to protrude from both side surfaces of the support part in the circumferential direction, and
- the support part and the coil winding part are disposed in a cross shape,
- wherein a radius (STCR) from a virtual point (C) to a center of the coil winding part is obtained by the following formula.
- STCR=√{square root over (((STOR2+STIR2)/2))}
- wherein STOR is a radius from the virtual point (C) to an outer side of the support part, and STIR is a radius from the virtual point (C) to an inner side of the support part.
(canceled)
A stator comprising:
- a stator core;
- an insulator disposed on the stator core;
- and
- a coil wound around the insulator,
- wherein the insulator includes a main body on which the coil is wound, an inner guide configured to protrude from an inner side of the main body, an outer guide configured to protrude from an outer side of the main body, a protruding part disposed between the inner guide and the outer guide and configured to protrude from the main body, and a groove formed in an upper portion of the protruding part.
A motor comprising:
- a shaft;
- a rotor disposed outside the shaft;
- a stator disposed outside the rotor;
- and
- a housing configured to accommodate the rotor and the stator,
- wherein the stator includes a stator core, an insulator disposed on the stator core, and a coil wound around the insulator,
- the insulator includes a main body on which the coil is wound, an inner guide configured to protrude from an inner side of the main body, an outer guide configured to protrude from an outer side of the main body, a protruding part configured to protrude from the main body, and a groove formed in an upper portion of the protruding part, and
- the groove is formed from an inner side surface of the protruding part to an outer side surface of the protruding part.
