“…The concentrated winding of fractional slot and modularity technology are usually adopted. Due to the contact of adjacent coils between modules, it is easy to diffuse to other coils after local coils fail [1][2][3]. Therefore, a novel unwinding stator module combined permanent magnet synchronous machine (SMCPMSM) is proposed in this paper.…”

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.

This paper presents surrogate-model based optimization for synchronous reluctance motor (SynRm) with transversally laminated rotor. A radial basis function (RBF) model with 12 input variables and three outputs is first trained. A dataset is obtained using finite element method to estimate parameters of RBF model. By building RBF model, the RBF network can predicts the outputs of the SynRm with good accuracy Using non-dominated sorting genetic algorithm (NSGA II), pareto front is obtained. The SynRm is designed to maximize the maximum developed torque and power factor of the motor with constrained torque ripple.

Fractional slot concentrated winding (FSCW) permanent magnet synchronous machines (PMSMs) have been a research hotspot over the past few decades. Recently, the magnetic gearing effect in FSCW PMSMs is revealed along with its gear ratio which is a function of slot/pole number combination. At the design stage of FSCW PMSMs, one of the key issues is the selection of the slot/pole number combination. This paper shows that the gear ratio can contribute to a proper slot/pole number selection in any multi-phase FSCW PMSMs by acting as a unified index for a quick overall performance comparison. In the paper, firstly, the magnetic gearing effect in FSCW PMSMs is explained and the gear ratio is further discussed. The advantages of adopting gear ratio as the overall performance index over other indices are revealed. The influence of the gear ratio on the winding factor, torque output, cogging torque, inductance and rotor losses of 3-and 6-phase FSCW PMSMs are analyzed and validated by experiments, thus proving the analyses.
