Abstract: A submersible permanent magnet synchronous motor ( SPMSM) with external rotor and progressive cavity pump( PCP) integrated was designed. The PCP was embedded into the motor as a whole to shorten the length of the system and improved the downhole passing ability. The scheme of integrated oil production system of external rotor SPMSM and PCP was determined, and the calculation of SPMSM electromagnetic and structural parameters was carried out. Based on the traditional Taguchi method, Taguchi iterative method was proposed for parameter optimization of the new designed motor. By comparing with the global optimization results of genetic algorithm, the rationality of the Taguchi iterative method as a fast and accurate design optimization method for permanent magnet synchronous motor ( PMSM) was verified. Finite element analysis for the motor after optimization was conducted to calculate its magnetic density, no-load back EMF, torque, etc. , and verify the performance of the external rotor SPMSM.

Key words: integrated of motor and pump, external rotor, submersible permanent magnet synchronous motor, Taguchi method, parameter optimization, analysis of electromagnetic
