Adopting the straight-line bearing and asynchronism electrical machineries of conical surface braking, operation is steady. 采用直線(xiàn)軸承及錐面制動(dòng)三相異步電機，運作平穩。
The surface generated by a straight line,the generator,passing through a fixed point,the vertex,and moving along a fixed curve,the directrix. 錐面由一條直線(xiàn)，即母線(xiàn)，通過(guò)一固定點(diǎn)，即頂點(diǎn)，沿一給定曲線(xiàn)，即準線(xiàn)，連續移動(dòng)而產(chǎn)生的平面。
