A motor has a field magnet assembly comprising a plurality of magnets arranged in the circumferential direction of the field magnet assembly such that like polarities face each other, and a plurality of magnet spacers disposed between the magnets, respectively. Consequently, leakage of magnetic flux of the field magnet assembly is minimized, and torque is improved as compared to a conventional motor having the same stacking and capacity. In a washing machine with the motor, the magnets and the magnet spacers are integrally attached to the outer tub of the washing machine. Consequently, the size of the washing machine is minimized. The sizes of the inner and outer tubs are increased when the washing machine according to the present invention has the same size as the conventional washing machine. Consequently, the capacity of the washing machine is increased.

A flux concentration-type motor includes a ring-shaped stator, in which coils are wound on a plurality of teeth radially arranged; and a rotor, located at the center of the stator, having a plurality of magnets arranged in a circumferential direction such that poles, having the same polarity, of the magnets face each other, and rotated by the interaction with the stator, so as to prevent the leakage of magnetic flux of the magnets, thereby improving the torque compared to a conventional surface mounted permanent magnet-type motor having the same volume, reducing the production costs, and facilitating the miniaturization of products.

A self-magnetized motor includes a stator adapted to rotate by electromagnetic interaction with a rotator, a plurality of slot teeth formed on and surrounding a through-hole of the stator, and an excitation pole adjacent at least one slot tooth having fewer projections than remaining ones of the slot teeth. The projections are formed on ends of the slot teeth facing the through-hole of the stator. According to one non-limiting embodiment, the excitation pole may be formed between two slot teeth having fewer projections.

A single-phase induction motor includes a main winding, an auxiliary winding, a run capacitor, and a subsidiary start device. The auxiliary winding is configured such that the number of turns of the auxiliary winding, through which a current flows, varies according to the operating mode of the motor. When the motor starts, the number of turns of the auxiliary winding, through which a current flows, is reduced, thereby increasing the start efficiency of the motor. When the motor runs in normal mode, the number of turns of the auxiliary winding, through which a current flows, is increased, thereby increasing the operational efficiency of the motor.
摘要:
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.

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.

Provided is a method of preparing low-crystallinity oltipraz or amorphous oltipraz. The method includes: obtaining a mixed solution containing oltipraz and a water-soluble polymer or a water-insoluble polymer in a solvent, the solvent being an organic solvent or purified water; and solid-dispersing the oltipraz in the polymer. In the solid-dispersing, the mixed solution may be spray dried using a spray dryer or granulated using a fluid bed granulator.
