Abstract
A rotor for an electric motor may include a shaft and a rotor core. The rotor core may include an adjacent front surface, at least one of a plurality of apertures and a plurality of cavities protruding along a rotor core body, a plurality of magnets, and a resin fixing the plurality of magnets within the rotor core. The rotor may further include a manifold of resin formed on the front surface of the rotor core. The manifold may be at least partially overlapping with at least one of at least one aperture of the plurality of apertures and at least one cavity of the plurality of cavities. The manifold may be at least one of bonded and restrained via the resin to the front surface of the rotor core.
