  • Publication number: 20160315510
    Abstract: It is an object of the present invention to provide an axial gap type motor in which continuously wound coils can be easily assembled as a stator coil of the axial gap type motor, and the workability for the work of winding wires without any connecting wire on a gap surface can be improved. The axial gap type motor includes a stator and a rotator facing each other in a rotation shaft direction, and the stator is arranged with a plurality of cores and a plurality of winding wire coils wound around the cores arranged in a circumferential direction. First, second, and third winding wire coils are wound, with a single continuous conducting wire, around first, second, and third cores arranged in order adjacent to each other in the circumferential direction.

  • Publication number: 20160248313
    Abstract: Provided is a highly reliable and compact electric water pump. A motor unit includes an axial gap motor having a stator and rotors. A partition formed with a nonmagnetic member is interposed between the motor unit and a pump unit. A torque generated by the motor unit is transmitted to the pump unit by a contactless magnetic coupling in an axial direction. The partition is formed to have a bottomed cylindrical shape. The motor unit and pump unit are provided with driving magnets and passive magnets respectively which are opposed to each other with a cylindrical part of the partition between them.
