Abstract: A rotor core mold assembly including a rotor stack and a distribution plate. The rotor stack has a top surface and at least one rotor pole defined by a plurality of rotor stack cavities. Each of the plurality of rotor stack cavities has an aspect ratio defined by a width of a respective rotor stack cavity and a longitudinal length of the rotor stack. The distribution plate has a top surface and a bottom surface removably locatable on the top surface of the rotor stack to thereby form a fluid seal. The distribution plate includes a flow channel positioned on the top surface of the distribution plate and extending through the distribution plate, an injection gate in fluid communication with the flow channel, and a plurality of secondary flow channels coupled between the injection gate and the bottom surface of the distribution plate in fluid communication with the injection gate.

Abstract: A method of monitoring a magnetic orientation of a composite magnetic material injected into a rotor pole of a rotor core. The rotor pole is defined by at least one rotor cavity. The method includes injecting a magnetic composite material into the at least one rotor cavity defining the rotor pole and applying an external magnetic field to the rotor pole to magnetically orient the magnetic composite material during injection into the at least one rotor cavity.
