ABSTRACT:
An electric machine for a motor vehicle is provided, the electric machine generally comprising a claw-pole rotor and a stator circumscribing the rotor. Adjacent pole fingers of the rotor define a distance P representing the axial distance between the magnetic centers of the adjacent pole fingers. The stator generally includes a stator core defining a distance H representing the axial height of the lamination stack. Preferably, the electric machine has a ratio of P to H (P/H) in the range of 0.29 to 0.45, resulting in an improvement in the power output of the electric machine.
