Electromechanical impact of poles on the performance of double stator machine
Abstract
The electromechanical effect of rotor pole numbers on machine output parameters such as flux linkage, induced-voltage, torque, power and demagnetization of a double stator permanent magnet machine is presented in this study. The investigation is carried out through the application of MAXWELL-2D finite element software. The study revealed that the machine topology that has 11 rotor poles would have higher flux linkage, inducedelectromotive force, torque and power amplitudes compared with other analyzed machine types. Nevertheless, the machine type that has 14-rotor poles would have the largest output torque, if the machine types are subjected to the same amount of permanent magnet material or volume. Also, the 14-pole machine type has the widest-speed coverage, an excellent quality for traction and vehicle applications. Similarly, the results revealed that the compared machine topologies have good capability against demagnetization effects. The largest shaft torque produced in the 10-pole, 11-pole, 13-pole and 14-pole machine types is 1.37 Nm, 2.44 Nm, 2.28 Nm and 1.47 Nm, respectively.
