Parametric analytical-experimental modeling in BLDC engines applied to propulsion systems on Chopper motorcycles

Abstract:

The present experimental research proposes to analyze the behavior and performance of a three-phase Brushless BLDC electric motor when used as an alternative propulsion system in Chopper-type motorcycles. To carry out the study of the BLDC motor, an electric mathematical model is created and a mathematical model of the mechanical transmission system, with software the models are merged creating a universal equation applied to electric Chopper motorcycles, analytically with the variation of the electric angle (θe), the operating parameters were calculated: electromagnetic torque, power and efficiency, which are used as reference standards and compared with those obtained with field tests in the laboratory with the MotorLab Kit MLK-B, performing rpm tests under the standard IEC 60034-30, efficiency with the standard IEC 60034-31, Rated current with IEC 60038 and power under IEC 60034-30, with the experimental results is proposed optimized parameters for idle and load operation and implement them in the programming of a motor inverter and achieve the highest performance while meeting the quality standard for motorcycles set in EN 15194.
