This paper presents the influence of stator slot closure with magnetic wedge on different magnetic permeabilities in a motor designed specifically for cryogenic application. Calculation results of are obtained by simulation research on the basis of finite element analysis conducted using Flux2D computer program. Basing on the obtained results, it was found that the application of a magnetic wedge in cryogenic motor causes decreases of both the electrical current drawn and electromagnetic torque. Simultaneously, the magnetic flux in air-gap is more uniformly distributed when compared with a typical motor. As a consequence, the values of current harmonics of the motor also decrease.
