Analysis of winding induced voltage at constant RPM using computational method

Synchronous motor technology is more energy-efficient and cost-effective. It significantly impacts the development of science, especially in the field of transportation and industrial engineering. A synchronous motor is a brushless DC motor (Brushless Direct Current) which is a motor that has good efficiency, is more reliable, and has a longer life. The magnetic field comes from permanent magnets in the rotor and coils in the stator. The brushless DC motor system refers to the concept of an electromechanical circuit with a responsive and energy-efficient drive system. The system is built through electromechanics, electronic circuits, sensor systems, logic circuits, or micro-control algorithms. This study aims to develop a new method for designing a practical and efficient Synchronous Motor using a computational model as a simulation medium for the research results to be obtained. The finite Element Method (FEM) is a numerical technique for determining electrical machines’ electromagnetic parameters using the machine’s geometric dimensions and material properties. The method used is the finite element method using the Ansys Electronic 2018 software. The motor has good performance with electric current in each phase around 1.5 kA and a magnetic field flux of 0.02 Wb. the speed of the synchronous motor remains constant at 13300 rpm, which produces an induced line voltage and an induced phase voltage at a value of a maximum of 249.72 (volts) and 124.93 (volts).
