Aa. Afanasyev et An. Vorobyev, ANALYSIS OF THE MAGNETIC-FIELD OF A RECTIFIER-TYPE MOTOR WITH A NONUNIFORMLY MAGNETIZED ROTOR, ELECTRICAL TECHNOLOGY, (3), 1994, pp. 89-106
The method and results of analysis of the magnetic field and the elect
romagnetic torque in a permanent-magnet electric motor of the DVU type
with a rotor consisting of ferrite-strontium permanent magnets with b
oth radial and tangential magnetization parts are considered. Measures
for optimizing the geometry of the stator and rotor are indicated, an
d the possibility of using motors with rotors with various types of ma
gnetization is assessed.
