It is finished to a size that fits in the space created by the magnetic circuit component 7 and the magnetic circuit component 7, and its surface is insulated with a resin coat.
また２本のリード線８は磁気回路部品７の一部分を欠き
制御部に接続出来るようにして有る。Further, the two lead wires 8 have a portion cut out from the magnetic circuit component 7 so that they can be connected to the control section.

If you connect a circuit that drives an M-type stepping motor, it will rotate intermittently according to the number of output pulses.

そのため従前のファンモータと同様にホール素子などで
磁極検出を行ない、励磁の磁極を決定する必要がある。Therefore, as with conventional fan motors, it is necessary to detect the magnetic pole using a Hall element or the like to determine the excitation magnetic pole.

本実施例では軸受は部に滑り軸受けを用いたが、転がり
軸受けを用いても同様の構造に出来るものである。In this embodiment, sliding bearings are used for the bearings, but a similar structure can be achieved by using rolling bearings.
