摘要： A rotary electric apparatus comprising a field magnet having different magnetic poles arranged alternately on a circumferential surface, an armature including an armature core having slots formed therein as distributed on a circumferential surface opposed to the magnetic circumferential surface, to provide salient poles between the slots, each of the salient poles having an armature winding wound therearound, and a shaft supporting either the armature or the field magnet rotatably, relative to the other. The magnetic poles of the field magnet or the slots of the armature core are formed at unequal spacings determined by some equations, so that positions where cogging occurs can be distributed.

摘要： A motor includes an armature and a field magnet which surrounds the armature. The armature includes a plurality of teeth being arranged at equal pitch, and the field magnet includes a plurality of magnetic poles being arranged at equal pitch. When the number of the magnetic poles of the field magnets is "2P" and the number of phases of divided armature windings is "Q", the number T of the teeth is determined in accordance with an equation T=(P.+-.N) Q (O

摘要： A frequency generator comprises a cylindrical rotor to which an annular multipolar magnet is fixed on the inner wall thereof. The multipolar magnet includes a plurality of magnetizable sectors arranged in a circumferential direction thereof, and adjacent magnetizable sectors are magnetized alternately in reverse polarity. Within the rotor, two disk-shaped magnetic plates are supported fixedly with a predetermined space axially. On the peripheries of respective magnetic plates, a plurality of salient poles are formed with a predetermined pitch in a circumferential direction thereof. The salient poles of each magnetic plate respectively constitute a salient-pole line. Between the two salient-pole lines, a generating coil is wound in a circumferential direction thereof. To each first and second salient poles to be paired, the magnetizable sectors of different polarity of the multipolar magnet are faced in divergence relatively in the circumferential direction. A magnetic flux from the multipolar magnet interlinks with the generating coil by the salient poles to be paired of the two salient-pole lines. Accordingly, in the generating coil, an alternating signal of frequency corresponding to the rotation numbers of the rotor is generated. When constituting a motor, a driving coil is wound on the teeth of the magnetic plate.
摘要翻译：频率发生器包括圆柱形转子，环形多极磁体固定在其内壁上。多极磁铁包括沿其圆周方向布置的多个可磁化扇区，并且相邻可磁化扇区以相反的极性交替地磁化。在转子内，两个盘状磁性板以轴向固定地以预定的空间被支撑。在各个磁性板的周边上，在其圆周方向上以预定的间距形成多个凸极。每个磁板的凸极分别构成凸极线。在两条凸极线之间，沿着圆周方向缠绕发电线圈。对于要配对的每个第一和第二凸极，多极磁体的不同极性的可磁化扇区在圆周方向上相对地发散。来自多极磁体的磁通量通过由两个凸极线对成对的凸极与发电线圈相互连接。因此，在发电线圈中产生与转子的旋转数相对应的频率的交变信号。当构成电动机时，将驱动线圈缠绕在磁板的齿上。
