چکیده
Synchronous homopolar motors (SHMs) with an excitation winding located at the stator and a toothed salient pole rotor are good alternative to traditionally used in traction applications such as induction or interior permanent magnet synchronous (IPMSM). This study presents results of theoretical comparison between IPMSM SHM application constant power speed range 1:10, which is specific mining truck drives, rated 370 kW. The considered have same number phases, poles slots, outer diameter lamination. design optimized using Nelder–Mead method. main objectives optimization minimize average losses operating cycle limit required semiconductor inverter. performance compared previously obtained by Although approximately equal, high for about two times greater than low maximum torque, means that there need intensify cooling system deterioration reliability. advantage reduction length active part 30%. 4.6 lower cost materials. In addition, more reliable IPMSM, no risk overheating, demagnetization degradation magnets over time.
