Abstract: Based on the direct drive submersible applications,the cylindrical permanent magnet linear synchronous motor was researched and developed.Modular structure of laminated stator core,axial magnetizing magnet structure and 9-slot/10 pole motor prototype motor modules compose the protoype motor.And the use of dynamic seal type to meet the actual requirements of harsh environments sealed.Through electromagnetic analysis a low power engineering prototype motor was designed.The performance test was carried out.The test result shows that the protoype motor has higher power,high efficiency,and can meet the actual project needs.This process prouides a good foundation for the production of actual motor.
Key words: cylindrical permanent magnet linear synchronous motor;direct drive submersible pump;prototype motor test
