  • Slotless motor
    Patent number: 7990013
    Abstract: A stator coil of a slotless motor is disclosed in which the stator coil is formed in such a manner that respective both distal ends of two unit coil bodies, each unit coil body arranged to face each other, are respectively coupled to form a plurality of circular coil bodies, each circular coil body having a different inner diameter, and a circular coil body having a smaller inner diameter is sequentially inserted into an inner side of a circular coil body having a larger inner diameter, whereby a horizontal width of the plurality of unit coil bodies of U, V and W phases is equal there among to cause the strength of the magnetic field of U, V and W phases to be equal, and to allow the stator to be accurately manufactured, thereby catering to a designer's intention and markedly simplifying the assembly processes.
    Type: Grant

  • Permanent magnet motor having stator poles with stepped-end-surfaces and rotor with outer-circumferential-recessed surface
    Patent number: 7550891
    Abstract: A permanent-magnet motor including a rotor having permanent magnets disposed therein, and a stator, wherein an outer circumferential surface of the rotor is opposite to an inner circumferential surface of the stator, and one or both of the outer circumferential surface of the rotor and the inner circumferential surface of the stator are varied in a radial direction so as to provide a non-uniform gap between the two surfaces to approximate sinusoidal change in magnetic flux.
