Design, Analysis and Multi-Objective Optimization of a New Asymmetric Permanent Magnet Vernier Motor for Low-Speed High-Torque Applications

Machines
This paper proposes a new Asymmetric Permanent Magnet Vernier Motor (A-PMVM) for low-speed high-torque applications. Unlike conventional symmetric V-shaped PMVMs (SV-PMVMs), the A-PMVM features irregular U-shaped magnet arrays composed of asymmetric V ...
