Designing a low cost high performance permanent magnet motor drive system

Exploit the flux concentration design is good alternative for designing a relatively low cost synchronous motor based on ferrite magnets. The paper discusses the design of the feedback control laws for the stator current and mechanical speed of a synchronous motor in which the magnets are placed transversely along the rotor radius. The dynamic modeling as well as the parameter identification of the motor have been performed. Simulation and experimental results are presented to demonstrate the correctness of the methodology and the feasibility of proposed motor design and its related feedback control laws.
