Abstract
A rotor assembly used in an electric motor, includes a rotor having an inner diameter, an outer diameter, and a plurality of rotor slots; a plurality of permanent magnets received within the rotor slots; and a rotor plate having an inner diameter, an outer diameter, and an outer lip extending away from a radial face of the rotor plate toward the rotor, wherein an adhesive bonds the rotor plate to a radial face of the rotor.

A rotor assembly used in an electric motor, comprising:
- a rotor having an inner diameter, an outer diameter, and a plurality of rotor slots;
- a plurality of permanent magnets received within the rotor slots;
- and
- a rotor plate having an inner diameter, an outer diameter, and an outer lip extending away from a radial face of the rotor plate toward the rotor, wherein an adhesive flows from one end of the rotor slots to another end of the rotor slots to bond the permanent magnets to the rotor and the rotor plate to a radial face of the rotor.

A method of assembling a rotor assembly, comprising the steps of:
- (a) orienting a rotor plate on a side so that rotor pads and an outer lip face of the rotor plate upwards;
- (b) placing a rotor on top of the rotor pads so that a radial face of the rotor contacts the rotor pads;
- and
- (c) applying an adhesive to an opposite radial face of the rotor so that the adhesive flows through rotor slots of the rotor toward the rotor plate yet is contained by the outer lip thereby bonding the rotor plate to the rotor.
