In the paper, the numerical simulation is conducted on the motor electromagnetic force firstly. Radial force waves of the motor are the main reason for causing electromagnetic vibration and noise. Then, electromagnetic forces are mapped into a structural model for computing electromagnetic vibration. Computational results are compared with experimental results, so the correctness of the computational model is verified. Then, electromagnetic noises are computed according to the vibration data of the motor. Electromagnetic noises of the motor are axis-symmetric in plane and plane. In plane , the electromagnetic noise of the motor is skew-symmetric relative to a 45° angle. In plane and plane , the noise is caused by the vibration of the end cap, while noise in plane is caused by electromagnetic radial forces. In addition, the motor electromagnetic noise has an obvious directivity. The motor also has obvious

“…is the winding coefficient of the fundamental MMF. According to formula (11) and (13), the EMF and MMF of the winding are reduced slightly after several coils are removed. The rotor flux linkage can be increased by slightly increasing the length of the iron core to ensure that the product of the rotor flux linkage and the stator current keep unchanged after coils are removed, so that the rated working point and the overload capacity of the SMCPMSM remain unchanged.…”

The large permanent magnet synchronous machine(PMSM) usually adopts modularity technique to facilitate the manufacture and maintenance. In order to avoid the contact of adjacent coils between modules, a novel unwinding stator module combined permanent magnet synchronous machine (SMCPMSM) is proposed, in which each modular can operate independently. The number of input modules can be flexibly selected according to the torque requirement in the SMCPMSM of mill wrapping around to realize the optimal control of mill system efficiency. In this paper, the unwinding block method and its mathematical model of the SMCPMSM are described. The electromagnetic performance of the SMCPMSM and the operation performance of different power supply modules (PSMs) are analyzed, the radial force and electromagnetic vibration of the PSM in asymmetric operation is studied, which provides a reasonable basis for the part of PSM operation of the SMCPMSM in accordance with torque requirements.

An accurate prediction of modal characteristics of motor stator is essential in order to design a low vibration motor and to operate it quietly. Scholars have done a lot of research on the modal analysis of stator core and winding. However, there are few papers for the 0th-order mode shape and frequency of the stator system. This paper aims to propose a new stator system analysis model, which can effectively analyze the 0th-order mode and improve the model calculation efficiency. Firstly, the modal of stator core and stator core-winding system were analyzed theoretically. Secondly, four stator system finite element analysis models were established. The modal analysis of the stator core and stator core-winding system were carried out using the four models. The validity and computational efficiency of the four models of the stator core and stator core-winding system were compared. A new stator system analysis model was proposed. Thirdly, the modal tests of the stator core and stator core-winding system were carried out by hammering method, and the validity of the finite element analysis model was verified. Compared with the traditional model, the newly proposed model can analyze the 0th-order mode more effectively and improve the computational efficiency.
