The Exploitation and Design of Large Brushless Synchronous Machine For Ball Mill

In this paper, it is resumptively introduced that the technique entire content of the electromagnetic design of this kind of electromotor, and the structural design of his kind of electromotor, and so on. In the whole electromotor design, the factor adopting air clutch is considered enough. Brushless exciter is a pivot of the design and exploitation. The whole processes that the control module coordinately controls the exciting circuit, and accomplishes excitation are elucidated concisely. For overload of the electromotor, master control system increases the excitation of the exciter, raises it's imaginary component, finally makes the main engine be placed in the over excitation, and raises it's overload capacity after master control system judges feedback. The exploitation of the large brushless synchronous machine for ball mill filled up the domestic blank of this aspect. In the aspects of new product exploiting and electric machine product being in line with nations, this is a beneficial trial.
