a high-power electric motor 大功率电动机
Copper alloy with high conductivity and high strength is widely used for wind mill generator and pulling motor used for electric express locomotive to reach to high power and small in size.
风力发电机、高速电力机车用牵引电机等，为达到大功率、小体积的使用效果，广泛使用高导电性和高强度的铜合金。
The proposed power supply is also well suitable for use in high power application such as electric utility and large motor drive systems where a great number of power electronic devices are involved.
使用在大功率的装置中，新型电源也可以很好地适应那些具有大量功率电子器件的如多用途的大型电机驱动系统的需要。
On starting, this electric motor has high impedance and power factor, low current, and large torque.
电动机起动时阻抗大、电流小、功率因数高、转矩大；
