Abstract:

The purpose of the work is first to study the behavior of a semiconductor platelet in the presence of a rotating electric field or potential distribution. It is shown that the Hall effect leads to the creation of an equivalent reactance independent of amplitude, and, to a large degree, of the frequency of the rotating field. This reactance, depending on the sense of rotation, is an inductive or capacitive reactance. One application of this property is automatic starting and speed regulation of a single phase induction motor. This motor has a generally fixed inductor, whose single phase winding, as supplied by an industrial distribution network, creates an ac sinusoidal magnetic field. It also has a rotor with a short circuited polyphase winding.
