It is mainly composed of three parts: transducer, alarm device and magnetic field exciter.
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).
通电螺线管里的电流产生里一个移动磁场，以非接触的方式驱动车辆。
