The frequency changing start up process of generating unit actually is a synchronous driving process under the action of electromagnetic moment of the stator and rotor of motor.
机组变频起动过程，实际上是电动机依靠定子和转子的电磁力矩作用的同步驱动过程。

The finished rotor and statorunit is then assembled into a central motor housing unit. The motor assembly is then subjected to a High-Potential (Hi-Pot) Test.
转子和定子成品然后装配进中央电机壳装置内。随后电机总成需经过高电压测试。
