    • The side wall of a motor casing is formed into a quadrangular shape such that four flat side portions, and arcuate corner portions located at respective corners are continuously joined together. A field magnet having a quadrangular external shape is formed such that four flat side portions, and four arcuate corner portions located at respective corners are continuously joined together. The arcuate corner portions of the motor casing and the arcuate corner portions of the field magnet extend along respective circles having a center located at the center of a motor shaft, and the central angles of the arcuate corner portions fall within a range of 15° to 35° inclusive. The field magnet is press-fitted or bonded into the motor casing such that the corner portions of the field magnet come into close contact with the corner portions of the motor casing.

    • A redundantly constructed protection channel access transmission apparatus includes current units and spare units by which protection channel access data can be transmitted even if any one of the current units or spare units is in an alarm state. In a normal state, the current units transmit work data and the spare units transmit the protection channel access data. When any one of the current units is in an alarm state, a selector selects work data and supplies the work data to a secondary spare unit. Then, the secondary spare unit performs a signal processing in place of the current unit. On the other hand, when any one of the spare units is in an alarm state, the selector also selects protection channel access data in the same way and the secondary spare unit performs a signal processing in place of the spare unit. With this arrangement, even if any one of the current units or spare units is in an alarm state, the secondary spare unit is selected and processes the signal of the current unit or spare unit in the alarm state, whereby both of the work data and protection channel access data can be transmitted as they are.
    • 冗余构造的保护信道接入传输装置包括当前单元和备用单元,即使当前单元或备用单元中的任何一个处于报警状态,也可通过该单元和备用单元发送保护信道访问数据。 在正常状态下,当前单元发送工作数据,备用单元发送保护通道访问数据。 当任何一个当前单元处于报警状态时,选择器选择工作数据并将工作数据提供给辅助备用单元。 然后,辅助备用单元执行信号处理代替当前单元。 另一方面,当任何一个备用单元处于报警状态时,选择器也以相同的方式选择保护信道访问数据,次备用单元执行信号处理代替备用单元。 通过这种布置,即使当前单元或备用单元中的任何一个处于报警状态,二次备用单元被选择并处理处于报警状态的当前单元或备用单元的信号,由此工作数据和 保护通道访问数据可以原样传输。

    • A side wall of a motor casing is formed into a polygonal shape such that flat side portions and corner portions located at respective corners between the side portions are continuously joined together. A field magnet, which has an outer circumferential shape approximately coinciding with the inner circumferential shape of the motor casing, has magnet side portions and magnet corner portions, and has a rib provided on outer circumferential surfaces of the magnet side portions. The magnet is disposed, through press-fitting, within the motor casing such that at least the rib comes into contact with the inner circumferential surface of the motor casing, wherein the magnet side portions, excluding the rib, are formed such that small clearances are formed between the magnet side portions and the side portions of the motor casing, or at least such that no pressing force acts on the magnet side portions, excluding the rib.
    • 电动机壳体的侧壁形成为多边形,使得位于侧部之间的各个角部处的平坦侧部和角部连续地接合在一起。 具有大致与电动机壳体的内周形状大致一致的外周形状的磁铁具有磁铁侧部和磁铁角部,并且在磁铁侧部的外周面上设有肋。 磁体通过压配置设置在电动机壳体内,使得至少肋与电动机壳体的内周面接触,其中除了肋之外的磁体侧部分形成为小间隙 形成在电动机侧部分和电动机壳体的侧部之间,或者至少使得除了肋之外,没有压力作用在磁体侧部分上。
