Abstract

In order to produce rotary motion in an electrical machine, the current in the rotating part must always react with the magnetic field so that it produces a force which acts in one direction only. In a d.c. machine this action is brought about using a static magnetic field, whereas in a.c. machines the magnetic field rotates at high speed (see also section 7.2).
