Abstract： Therimthruster adopts the integrated motor technology， which is greatlydiferent fromthe traditional motor.Inthis paper，ANSYS Maxwellfinite element method is used to studythe infuence of thredesign parameters of permanent magnet motor structure，namely，stator slot width，electrode arccoefficient and centrifugal height on the performance of tooth pitch torque.The response surface method is creatively proposed to significantly reduce the tooth pitch torque and torque pulsation，optimize the stability of permanent magnet motor torque and effectively improve the efficiency of rim motor.

Key words： rim driven thruster; permanent magnet motor; cogging torque; motor efficiency
