Abstract
A permanent magnet machine, a rotor assembly for the machine, and a pump assembly. The permanent magnet machine includes a stator assembly including a stator core configured to generate a magnetic field and extending along a longitudinal axis with an inner surface defining a cavity and a rotor assembly including a rotor core and a rotor shaft. The rotor core is disposed inside the cavity and configured to rotate about the longitudinal axis. The rotor assembly further including a plurality of permanent magnets for generating a magnetic field which interacts with the stator magnetic field to produce torque. The permanent magnets configured as one of internal or surface mounted. The rotor assembly also including a plurality of retaining clips configured to retain the plurality of permanent magnets relative to the rotor core. The pump assembly including an electric submersible pump and a permanent magnet motor for driving the pump.
