Iron loss calculation in a claw-pole structure
Author
Summary, in English
The total core loss in a claw-pole structure has been calculated on the basis of the variation of the magnetic loading over the magnetization cycle in different parts of the machine. This variation has been estimated from a lumped parameter permeance network and 3D finite element simulations, studying the flux density waveform and loci in their elements. The results from the simulations are compared with the loss measurements in a single-phase claw-pole motor equipped with an outer permanent-magnet rotor. Results show that the static and dynamic losses are underestimated by 35% and up to 60% at 100Hz respectively. Finally, the results from an optimization process are presented, where the torque performance is evaluated as a function of the pole number and dimensions of the machine
