• Analytical model (AM)
• Carter's coefficient
• effective airgap
• electrical machines

Analytical models of electric machinery often utilize Carter's coefficient to account for the increased airgap reluctance due to flux entering the sides of the stator teeth. In this letter, a modified coefficient is proposed to account for wide stator slots, wherein a component of flux directly enters the stator backiron. The proposed coefficient is implemented in an analytical model of a wound rotor synchronous machine and is validated using two-dimensional (2-D) finite element analysis.
