Motors within the range 0–1.0 hp vary in construction and exhibit vastly differing characteristics depending upon the application. This chapter gives a brief insight into the cha

J. E. Maldonado,J. Maigne,D. Lecoq induction motor was developed a short time later. Because of its simplicity and cheapness, the 3-phase squirrel-cage induction motor is now by far the most common type of motor in use for driving industrial plant, particularly of small power ratings (up to 20 kW). The slip-ring induction motor is n

Due to the action of the commutator the voltage appearing between brushes placed on the commutator has the same frequency as the rotating field irrespective of the speed of the armature, but its magnitude depends on the relative speed and the

The Pathophysiology of Hemorrhoids,es as when operating as an alternator, it runs as a motor at synchronous speed, the speed being determined by the frequency of supply and the number of poles : .The name of this type of motor is derived from the fact that it has to run at the synchronous speed, which keeps it in step with the supply frequency.
