RADIAL MAGNETIC FORCES OF SINGLE-PHASE PERMANENT SPLIT-CAPACITOR MOTOR

Valéria Hrabovcová – Pavol Rafajdus

   This paper deals with investigation of radial forces developed in an unsymmetrical air-gap of a single phase induction motor to avoid noise operation. The calculation is made on the basis of magnetic field analysis by means of FEMM. It is shown that eccentricity of the air-gap has a significant negative influence on the machine operation.

Keywords: radial magnetic forces, single-phase permanent split-capacitor motor, air gap eccentricity, slot harmonics, magnetic field analysis, noise and vibration of electrical machines
