It is mainly composed of three parts: transducer, alarm device and magnetic fieldexciter.
研制的带压作业油管接箍探测仪主要由传感器、报警器、激磁器等部分组成。

Since HSY requires dc magnetic field, an exciter with control circuitry is needed in addition to the conventional PMSY drive unit when employed as a motor.
HSY作为电动机使用时，由于需要直流磁场，与普通pmsy的驱动单元相比，应额外增加一个励磁电路。

Electric current in the cable winding generates a traveling magnetic field which pulls the vehicle along without contact. The support magnets form the exciter (i. e. the motor).
