Taking PM type(the permanent magnetmodel) SLPMU -025A motor as an example , this paper makes analytical calculation of its efficiency characteristics by the means of equivalent circuit.
Magnetic properties of a model nanocomposite magnet were calculated by means of computer simulation, and the effects of the amount of the soft magnetic phase on them were studied.
