Magnetic Flux Leakage Simulation and Analysis of Permanent Magnet DC Motors Based on Magnet |
| |
| Abstract: | After the analysis of the flux leakage mechanism of permanent magnet DC motors, finite element model and boundary conditions were established based on the software Magnet.The motor magnetic field was simulated under different conditions.Different flux leakages were obtained under different boundary conditions.The calculated results agree with the results of the test in the motor and proves that theoretical calculation is right. |
