Journal of Physics: Conference Series, 2021 Abstract The purpose of this paper is to evaluate the efficiency of a BLDC motor in regenerative braking mode. The mode of operation of the BLDC motor using its torque-slip characteristics is taken into consideration to evaluate its performance. The simulation, characteristics and the tabular column are all got from the MATLAB simulation.
