Taking PM type(the permanentmagnet model) SLPMU -025A motor as an example , this paper makes analytical calculation of its efficiency characteristics by the means of equivalent circuit.
When designed, the high-speed generator with a permanentmagnet(PM) rotor is preferred because of its simple structure, without excitation high energy density of the PM material.
