Abstract: A rotor for a motor includes a plurality of laminations. Each lamination includes a central opening having an outer surface. The outer surface is defined by a continuous non-circular curve. A shaft includes a cylindrical portion configured to engage the outer surface. The cylindrical portion is sized to define an interference fit between the cylindrical portion and at least a portion of the outer surface.

Abstract: A rotor for a motor having a rotor core length includes a shaft including a cylindrical portion and a shaft sleeve having a cylindrical opening. The shaft sleeve is coupled to the shaft such that the cylindrical opening and the cylindrical portion define an interference fit. A rotor sleeve extends the rotor core length and includes a cylindrical outer surface and an inner surface. The inner surface is spaced a non-zero distance from the shaft sleeve to define a space. A resilient material is disposed within the space and is bonded to the shaft sleeve and the rotor sleeve.
