Abstract
A magnetic pole module, an electric motor rotor and a method for manufacturing the electric motor rotor are provided. The electric motor rotor includes a rotor yoke and multiple magnetic pole modules disposed on the rotor yoke, each of the magnetic pole modules including a base plate, a housing, and a pair of magnetic pole units that are accommodated in an accommodating space formed by the base plate and the housing and have opposite polarities, and a pair of magnetic pole units in each of the magnetic pole modules are spaced apart from each other by a first distance in a circumferential direction of the rotor yoke. The electric motor rotor can give consideration to the properties, such as cogging torque and torque pulsation, of a generator, the protection of magnetic poles and the mechanical fixation of the magnetic pole.
