Controlling the level of noise in electrical motors is critical to overall system performance. However, predicting noise of an electrical motor is more difficult and less accurate than for other characteristics such as torque-speed. Recent advances have produced powerful computational methods for noise prediction, and Noise of Polyphase Electric Motors is the first book to collect these advances in a single source. It is also the first to include noise prediction for permanent magnet (PM) synchronous motors.

Zheng Chenggong (1624 - 1662) was sired by Chinese merchant-pirate in Hirado, Japan. A general at the end of the Chinese Ming Dynasty, he was a prominent leader of the movement opposing the Manchu Qing Dynasty, and in recovering Taiwan from Dutch colonial occupation in 1661. Honored as a hero in Japan, China, and Taiwan, he has been dramatized in many plays in various theatre forms in Japan (since about 1700), China (since 1906), and Taiwan (since the 1920s). Yet his portrayals in these plays are drastically different, depending on the dramatists' intention of writing, view of history, and...
