Divided Teeth Switched Reluctance Motor with Different Tooth Combinations

In this article, three novel divided-teeth switched reluctance motors (SRMs) with 24/26, 36/38, and 48/50 tooth combinations are proposed. First, the topologies of the proposed SRMs are introduced. Next, the three divided teeth SRMs along with a conventional 12/10-pole SRM are simulated using a 2-dimensional finite element method (FEM) and the results are obtained and compared concerning distributions of magnetic flux density, flux linkage, static torque, and maximum and average torque. The results indicate that as the number of teeth augments, the output torque of the motor enhances. Hence, the 48/50-tooth SRM produces the largest average torque among all proposed motors, which may be selected as an appropriate choice for high-torque applications. Finally, the steady-state results of the 48/50 motor are obtained using a chopping current control (CCC) to illustrate the normal working of the machine.
