Abstract
The paper includes simulation results of the Hybrid Excited Claw Pole Generator with skewed and non-skewed permanent magnets. The test machine has claw poles on two rotor sections, between which an excitation control coil is placed. The novelty of this machine is existence of non-skewed permanent magnets on claws of one part of the rotor and skewed permanent magnets on the second one. The paper presents the construction of the machine and analysis of the influence of the PM skewing on the cogging torque and back-emf. Simulation studies have shown that during increasing of skew angle the cogging torque first decreases, achieves a minimal value when skew angle is 9°, and then increases.
