Abstract
This paper describes a new variable-field motor that can be driven over a wide range of speed. This motor is a type of interior permanent magnet synchronous motor (IPMSM), and two kinds of Nd-Fe-B magnets with different coercive force are used. The motor model proposed in this paper can improve the motor variable speed range and efficiency compared with a basic motor model. No-load, load, and stress analyses are carried out using FEA simulations. According to simulation results, the torque of the new motor model approximately equals that of the basic motor model, and the speed can be achieved more than 250 % of that in the basic model.
