Github Tangguhbayuw Electric Motor Efficiency Mapping This paper presents the work done to develop a dynamometer for electrical motors with a power capacity of up to 10 kw to be used in small and utility electric vehicles. Each motor has a pdf summary with some basic data like torque constant, resistance, and test parameters, as well as a few plots. here's what these plots are, and how you could possibly use the data.
Electric Motor Dynamometer Mechanical Engineering Portfolio Electric vehicle motors must deliver high efficiency across a wide range of speeds. therefore, it is important to create an efficiency map that illustrates how efficiently the motor operates at various rotational speeds and torque levels. After logging a text file from putty and saving to a directory, we processed and visualized the rpm, torque and efficiency of the motor with a contour map in matlab. Simulation results were used to validate the performance of the proposed design in terms of the state of charge (soc), transmitted energy, motor efficiency, battery temperature, and slip ratio. The study evaluates both total drive cycle energy efficiency errors and pointwise deviations across the torque–speed envelope for various grid resolutions. results are compared against laboratory based time stepping measurements to identify trade offs between computational efficiency and accuracy.
