It is surly important to control the speed; keep it constant and reduce it safely with desired time while the direct current motor is fulfilling the requested torque. Therefore, we designed a complete direct current motor operation system and analyzed its performance by using MATHEMATICA 10 Software. In order to simulate the direct current motor, three types of identical motor parameters such as separately excited, shunt, and permanent magnet, based on the catalogue values, are constructed.

Research paper thumbnail of The optimal hall sensor’s position for brushless direct current machine: experimental study

It is quite a difficult task to determine the exact and accurate rotor position to locate the hall sensor in a way that will have the most efficient impact on the operation parameters of a motor. In addition to theoretical work, experimental studies are required to operate a motor in steady state conditions. Therefore, special attention is being paid while measuring harmonic, torque, and speed values depending on the hall sensor's position. Experimental results of BLDCM are discussed and comparative analysis is performed. The results of this study are supported by theoretical information as well.

In this study, dimensions and their interdependencies of BLDC motor were calculated, analysed, and optimized. At first, experiments and simulations have been carried out to obtain reference parameters. Afterward, slot dimensions have been studied in particular. After checking that the experimental data and simulation data are compatible, optimization studies were carried out. In addition, magnet thickness, skewness, magnet type, embrace and steel type were parametrically investigated in detail. As a result, the improved efficiency value as well as effect of the rated parameters on the efficiency was successfully determined and ssimulation results accomplishing performance characteristics were presented.
