    • When a wind velocity sensor detects a wind velocity higher than a predetermined level, a timer device starts a waiting timer function during an operation timer period shorter than the waiting timer period. After the waiting timer period is over, the waiting timer function is switched to an operation timer function, and a switching relay switches a generator to a motor only during an operation timer period. Then, a driving circuit performs a start assisting rotation. After the operation timer period is over, the waiting timer period re-starts. This process is repeated. When during this period, the number of rotations of a rotor monitored by a rotation number measuring device, based on the output voltage Vm of a three-phase conduction coil exceeds a predetermined number of rotations, the charging of a battery by a three-phase generator is started.
    • 当风速传感器检测到高于预定水平的风速时,定时器装置在比等待定时器周期短的操作定时器期间中开始等待定时器功能。 等待定时器周期结束后,等待定时器功能切换到运行定时器功能,切换继电器只在运行定时器周期内将发电机切换到电机。 然后,驱动电路进行起动辅助旋转。 运行定时器周期结束后,等待定时器周期重新启动。 重复此过程。 当在此期间,由转数测量装置监测的转子的转数基于三相导通线圈的输出电压Vm超过预定转数,电池通过三相充电 发电机启动。

    • Within a space surrounded by a lower core layer, an upheaval layer, and a back gap layer, there are a plurality of first coil pieces arranged in a height direction and covered with a coil insulating layer. On the coil insulating layer, the upheaval layer, and a layered product formed on the back gap layer, a plurality of second coil pieces are arranged in the height direction with an insulating layer therebetween. Between the lower core layer and the first coil pieces, raised layers are formed, and the first coil pieces are in contact with the second coil pieces on connection surfaces exposed from the coil insulating layer on the raised layers.
