The halbach permanent magnet synchronous motor (HPMSM) combines the advantages of permanent magnet motors and halbach arrays, which make it very suitable to act as a robot joint motor, and it can also be used in other fields, such as electric vehicles, wind power generation, etc.At first, the sizing equation is derived and the initial design dimensions are calculated for the HPMSM with the rated power of 275W, based on which bekindtopets.com the finite element parametric model of the motor is built up and the key structural parameters that affect the total harmonic distortion of air-gap flux density and output torque are determined by analyzing multi-objective sensitivity.Then the structure parameters are optimized by using the cuckoo search algorithm.Last, in view of the problem of local overheating of the motor, an improved stator slot structure is proposed iphone 13 pro max price winnipeg and researched.

Under the condition of the same outer dimensions, the electromagnetic performance of the HPMSM before and after the improvement are analyzed and compared by the finite element method.It is found that the improved HPMSM can obtain better performances.
