The use of induction motors is the right choice for a great number of household appliances which look for cost-competitive solutions. Therefore, in the past few years, the energy consumption became also an important issue which drives the design of electrical motors, although, permanent magnet motors came to stay. Most of the solutions which are significantly efficient to worth using have also a high...
This paper presents an analytical method for calculating the effect of winding harmonics on the asynchronous torque of a single-phase line-start permanent-magnet motor. The method is an extension of earlier work, which combines symmetrical-component analysis with d-q-axes theory to model the various components of forward and backward rotating fields. The effect of individual winding harmonics is brought...
