As the prime motor of MCHP, it's ideal structure is free piston, but slope-plate or wobble-yoke is a practical choice.

燃气热气机作为MCHP的原动机，其最理想的是采用自由活塞结构，但是目前采用斜盘式或摆盘式传动结构则更为现实。

The pump consists of prime motor, multi stage centrifugal pump, seat, wire and control, in which the key part is the prime motor.

它由电念头、多级离心泵、底座、电缆和节制屏构成，个中电念头是该系统的要害部件。

The prime motor rotates in a fixed direction and the alternating motion of the carrier bar is accomplished by the crank-rocker mechanism.

电动机单向旋转，用曲柄摇杆机构换向，实现悬点的往复直线运动。
