Experimental investigation of a series wound DC motor for modeling purpose in electric vehicles and mechatronics systems

In our previous publication a model for serial wound DC motors was presented and a simulation program was described that is based on this model and had been developed in MATLAB environment. The recent publication presents the latest, extended version of the program and deals with the measurement of the electromagnetic and dynamic characteristics (electric resistances, dynamic inductances, bearing resistance and brush friction torque) of the above motor. From the measured characteristics, the program simulates the operation of the motor, calculating its torque, rpm and current intensity, as a function of time. To check the accuracy of the measured characteristics, and also the proper operation of our program, locked rotor response test measurements were carried out on the motor and their results were compared with the simulated ones. Finally, a recently developed heat energy recovery system is presented, which can be used on electrical drives.
