Cogging Torque Reduction in Surface-mounted Permanent Magnet Synchronous Motor by Axial Pole Pairing
In many machines, where permanent magnets are used, the effects due to cogging torque generated by permanent magnets (PMs) aggravate the output characteristics of the machines. This paper presents the method for reducing cogging torque in surface-mounted permanent magnet synchronous motor (SPMSM). A new cogging torque suppression method called axial pole pairing is proposed. Compared to convent...
متن کاملCogging Torque Minimization of Surface-Mounted Permanent Magnet Synchronous Machines Using Hybrid Magnet Shapes
This paper deals with the magnet pole shape design for the minimization of cogging torque in permanent magnet synchronous machines (PMSM). New shapes of permanent magnet are proposed. The magnet shape is modeled analytically by a set of stacked and well dimensioned layers relatively to the height and opening angle. The final shape of magnet is configured by using three models in view of obtaini...
متن کاملThe Effect of Magnet Width and Iron Core Relative Permeability on Iron Pole Radii Ratio in Spoke-Type Permanent-Magnet Machine: An Analytical, Numerical and Experimental Study
In this paper, we present a mathematical model for determining the optimal radius of the iron pole shape in spoke-type permanent-magnet (PM) machines (STPMM) in order to minimize the pulsating torque components. The proposed method is based on the formal resolution of the Laplace’s and Poisson’s equations in a Cartesian pseudo-coordinate system with respect to the relative permeability effect o...
متن کاملTopological modifications in function of cogging torque reduction of permanent magnet synchronous motor
In this paper the influence of some design parameters on the cogging torque development by a surface mounted permanent magnet motor is investigated. The investigation is focused on the implementation of stator core skewing and dummy slots in the stator teeth and their influence on the cogging torque reduction of the motor. The cogging torque is calculated numerically for the different motor sol...
متن کاملPole Shape Optimization of Permanent Magnet Synchronous Motors Using the Reduced Basis Technique
In the present work, an integrated method of pole shape design optimization for reduction of torque pulsation components in permanent magnet synchronous motors is developed. A progressive design process is presented to find feasible optimal shapes. This method is applied on the pole shape optimization of two prototype permanent magnet synchronous motors, i.e., 4-poles/6-slots and 4-poles-12slots.
