English term or phrase:is machined concentric to high tolerances
The squirrel cage AC motors are manufactured in laminated steel is machined concentric to high tolerances and designed to give typically more than 200% starting torque for 3-phase versions. 谢谢！
这里说的应该是鼠笼电机的硅钢片。“is”前面大概少了“which”，或者也可能“is”原本为“as”。“machined concentric to high tolerances”说的是这些硅钢片的加工，同轴度很高。装配成电机时，需多片硅钢片压在一起，所以得保证同轴度，这与硅钢片本身加工的公差密切相关。工科院校的机械系有一门课程叫“机械加工与公差”，讲的就是类似加工。硅钢片虽用在电机上，但其加工仍属机械加工范畴，一般由冲床一片片冲出来的，要做到很高的同轴度也着实不易。
