The result shows that the permanent magnet generator presents here has a series of advantage in size, weight, and efficiency over the wound-field generator.
另外，本文还设计了一台电励磁的交直流发电机，电磁设计结果表明，永磁电机在体积、重量、效率方面都很有优势。
Put pulley and rotor of the centrifugal together and made full use of magnetic field, the centrifugal permanent-magnet direct-current generator reduces the cost.
离心式永磁直流发电机把皮带轮与离心式转子设计为一体，磁场得到了充分利用，降低了成本。
