Abstract

In order to encompass greener transportation needs, electrical vehicle technology has come a big way. The Indian Automotive sector is also undergoing a breakthrough, with electric vehicles as one of the most promising options towards a cleaner and greener world. Presently Brushless DC Motors are considered as the best choice for electric vehicles due to their compact size, reliability and maintenance free operations. Brushless dc motors with inner and outer rotors are popular these days, and they are employed in electric bikes.The Lab model analyses, E-Magnetic analysis since the motor is coupled to the wheels of the vehicle, thermal and magnetic analysis are essential while developing an outer rotor BLDC Hub motor. It differs from a petrol engine motorcycle because the engine and the wheel are separate on a petrol engine motorcycle. As a result, any heating of the engine would not heat the wheel; but, because the hub motor and the bike wheel are not separated, heating of the hub motor would induce a similar type of heating in the wheels of an electric bike. If the hub motor's temperatures and total magnetic flux density rise above typical levels, the electric motorcycle may not start at all. This paper emphasizes on the E Magnetic analysis, Lab model analysis, and Thermal and Magnetic analyses on a 45 slot, 50 poles outer rotor BLDC motor developed in Ansys Motor-CAD. The paper clearly displays all of the E Magnetic plots and Lab plots acquired from the analysis. The various views of the model, including axial, radial, and schematic views, are also clearly depicted. This study project demonstrates how to properly examine a motor E-magnetically, which is the first and most significant step in analyzing the thermal and mechanical models in Ansys motor CAD.

Keyphrases: Brushless direct current (BLDC), Electric vehicle (EV) ANSYS, Finite Element Analysis (FEA)
