  • Patent number: 10483819
    Abstract: Disclosed herein is a stator assembly for a motor. The stator assembly comprises a stator core having a plurality of teeth around each of which a stator coil is wound, a first insulator coupled to one side of the stator core to provide insulation between one tooth and an adjacent tooth, a second insulator coupled to the other side of the stator core to provide insulation between one tooth and an adjacent tooth, and a three-phase terminal inserted between the stator core and the second insulator and protruded partially to the outside of the second insulator to be electrically connected to an inverter. According to the present invention, there are advantageous effects that since the three-phase terminal is assembled between insulators, breakaway and breakage of the three-phase terminal can be prevented and that insulation effect and assembly capability thereof are enhanced.

  • Patent number: 10205354
    Abstract: A brushless motor includes a rotor in which permanent magnets are provided on an inner circumferential surface of a rotor core, and a stator in which teeth are provided on respective ends of stator cores around each of which a coil is wound. Each of the teeth is formed such that the distance between a facing surface which faces the permanent magnet and an inner circumferential surface of the permanent magnet is increased from the center of the tooth to the end thereof. Therefore, the rate of variation in magnetic resistance in response to variation in position of the rotor can be minimized, whereby cogging torque can be markedly reduced.

  • Patent number: 4828875
    Abstract: Sintered films of Cd.sub.1-x Zn.sub.x S (0.ltoreq.x<1) with high optical transmittance are provided. These films are produced by applying a paste composed of powdered CdS and CdCl.sub.2 or of a mixture of CdS, ZnS and CdCl.sub.2 onto an appropriate substrate such as borosilicate glass, under an inert gas atmosphere containing ZnCl.sub.2 vapor or thereafter resintering the paste on the substrate under a nitrogen atmosphere.The ZnCl.sub.2 vapor is produced by heating ZnCl.sub.2 at 400.degree. C. or higher but below the temperature of 500.degree.-700.degree. C. to which the specimen is heated.The resulting sintered films have optical transmittance of 80% at long wavelength ranges or higher and can be used as a window layer having a superior optical transmittance in solar cells.
