Abstract
The magnetic field harmonics of pole pair difference one is the reason behind the lateral force production in an electrical machine. The eccentric motion of the rotor, generates magnetic field of pole pair difference one with respect to the torque producing component of the magnetic field. Due to the interaction of these fields, radial force called unbalanced magnetic pull (UMP) acts on the rotor. The present work is based on a special winding scheme called bridge configured winding (BCW) scheme which has inherent capability of diminishing eccentricity induced magnetic field harmonics when bridge currents are allowed to flow in the winding. The present work investigates the presence of harmonic components in the air gap and its effect on force production. An in-house 2D FE code of BCW induction motorh as been used for the investigation.
