Abstract
The described technology relates to a stator of a planar type motor and a planar type motor using the same, which are easy to manufacture and are capable of reducing core losses, thereby maximizing motor performance. First cores that are difficult to form by stacking electrical steel plates are formed of soft magnetic powders, and second cores that are formed by stacking electrical steel plates having the same size are arranged in a region where a vortex is concentrated, thereby allowing easy manufacture and being capable of maximizing the performance of the planar type motor.
Claims8
A stator of a planar type motor comprising:
- a support plate in which a plurality of first receiving grooves are formed in a circumferential surface thereof with a predetermined distance therebetween;
- a plurality of first cores inserted into the first receiving grooves, fixed to the support plate, and formed of a soft magnetic powder;
- second cores which are coupled to the plurality of the first cores, and in which electric steel plates having the same size are stacked in a direction perpendicular to the support plate and fixed to the first cores;
- and
- coils which are wound around and cover the first cores and the second cores.
A planar type motor comprising:
- a stator of a planar type motor;
- and
- a rotor positioned above the stator to be spaced apart from the stator and having a permanent magnet at a position facing the stator,
- wherein the stator of a planar type motor comprises:
- a support plate in which a plurality of first receiving grooves are formed in a circumferential surface thereof with a predetermined distance therebetween;
- a plurality of first cores inserted into the first receiving grooves, fixed to the support plate, and formed of a soft magnetic powder;
- second cores which are coupled to the plurality of the first cores, and in which electric steel plates having the same size are stacked in a direction perpendicular to the support plate and fixed to the first cores;
- and
- coils which are wound around and cover the first cores and the second cores.
