Frequency characteristics of bulk windings of asynchronous motors.

Abstract

The results of an experimental study of amplitude frequency characteristics of 4A series engines with a rotation axis height of 90 mm, a number of poles from 2 to 8 and a voltage of 380/220 V for different phase switching schemes are presented. The effect of the rotor and mixing of the windings in the groove on the wave resistance is studied. A comparison is made experimental and calculated data.
