  • Patent number: 7663335
    Abstract: A single-phase induction motor comprises a power consumption prevention device, which includes a current signal transfer element and a switching element. The switching element is turned on/off according to the current signal received from the current signal transfer element. The power consumption prevention device prevents current flow to a start device when the motor runs in normal mode, and thus avoids unnecessary power consumption by the start device when the motor runs in normal mode, thereby preventing a reduction in the efficiency of the single-phase induction motor due to the unnecessary power consumption.

  • Patent number: 7504753
    Abstract: According to the disclosed motor, since the motor includes a rotor in which a plurality of core pieces and magnets are alternately arranged in the circumferential direction, magnetic flux of the magnets is prevented from flowing between the core pieces neighbored with each other in the circumferential direction and the leakage of the magnetic flux can be minimized. Since identical polarities of the magnets neighbored with each other in the circumferential direction face each other, the magnetic flux can be concentrated to the respective core pieces. Moreover, since the axial direction of the circumference of the core facing the stator in the circumferential direction is longer than the axial direction of other portions thereof, torque is increased and manufacturing costs are reduced.

  • Patent number: 7474028
    Abstract: A motor includes a stator and a rotor rotated due to the interaction between the rotor and the stator. Since overhangs are protruded only from the circumference of a rotor core of the rotor facing the stator in the axial direction, manufacturing costs for improving performance and core loss of the stator are minimized. Additionally, since the rotor core is manufactured by iron powder metallurgy, the rotor core is conveniently designed.

  • Patent number: 7372184
    Abstract: A stator of a motor having various shapes and capable of minimizing the manufacturing costs. At least teeth are manufactured by the iron powder metallurgy method. In order to obtain the overhang effect, the height of a tip of each tooth is lower than the height of a rotor and the height of a yoke is higher than the height of a tip of each tooth so as to minimize the core loss of the yoke. Since, in order to minimize the end coil, the height of a neck of each tooth is gradually higher as running from the sides to the central portion in the circumferential direction, costs for manufacturing a motor can be minimized and sufficient efficiency can be obtained.
