The pressure fluctuations in a centrifugal pump at both design and off-design points and the internal electromagnetic field of canned motor are presented in this paper. The 3D unsteady flow numerical simulation is completed at different operating points by using the FLUENT. A sliding mesh technique is applied to take into account the impeller-volute interaction. The FFT technology is adopted to process those dynamic pressure data to reveal the frequency features. All the power spectrum results present that the pressure fluctuation amplitude of blade suction side is greater than the one of blade pressure side. Some unknown high-frequency contents are discovered in the flow field. Meanwhile, the canned motor designed are applied by the design method of permanent magnet synchronous motor. The internal electromagnetic field of the motor is simulated with the ANSOFT software. Magnetic field analysis is carried out between two different magnetic circuit structure: U-type and inverted U-type. Comparing to U-type magnetic circuit structure, the latter is more conducive to reduce the magnetic flux leakage in the iron core tooth.
