Chapter (11) Synchronous Motors Introduction It may be recalled that a d.c. generator can be run as a d.c. motor. In like manner‚ an alternator may operate as a motor by connecting its armature winding to a 3-phase supply. It is then called a synchronous motor. As the name implies‚ a synchronous motor runs at synchronous speed (Ns = 120f/P) i.e.‚ in synchronism with the revolving field produced by the 3-phase supply. The speed of rotation is‚ therefore‚ tied to the frequency of the source. Since
