    摘要： A motor cooling and eddy current suppression structure (100), which is attached to the surface of the motor winding (201), includes a first cooling plate (101), a second cooling plate (103,104), and a cooling water circuit located between the first cooling plate and the second cooling plate. The cooling water circuit is configured to allow the cooling fluid to pass through. The first and the second cooling plates are both non-magnetic metallic materials. The first cooling plate is divided into a plurality of individual first regions (301,303) which are corresponding to each pole of the motor by one or more first slits (305) provided on the first cooling plate in the position where the motor poles are combined. Each of the first regions is further divided into an even number of first sub-areas by at least one fist sub-slit (306) where induced electromotive force is generated. Two adjacent first sub-areas in respective first regions are grouped together, and the ends of each first sub-area that has the same polarity are connected in series. The second cooling plate is divided into a plurality of individual second regions which are corresponding to each pole of the motor by one or more second slits provided on the second cooling plate in the position where the motor poles are combined. Each of the second regions is further divided into an even number of second sub-areas by at least one second sub-slit where induced electromotive force is generated. Two adjacent second sub-areas in respective second regions are grouped together, and the ends of each second sub-area that has the same polarity are connected in series. This structure can efficiently reduce the temperature of the motor winding and reduce the induced eddy current.

    摘要： The present invention provides a power generator which can obtain efficient power generation by changing magnetic force acting on electromotive coils.The power generator is provided with a first permanent magnet member 1, a second permanent magnet member 2, and an electromotive coil member 3 arranged concentrically to have a telescoping structure and is configured so that power generation in the electromotive coil member 3 is induced by rotating the first permanent magnet member 1 or/and the second permanent magnet member 2. In the power generator, the first and second permanent magnet members 1 and 2 cooperate with each other to change the magnetic force and, thus, to obtain efficient power generation.
