Theoretical and Experimental Analysis of PMDC Motor in Hybrid Electric Vehicles

Abstract

In this modern world the applications of the electric motors have been very tremendous. The Auto mobile world is now switching from IC engine technology to hybrid electric technology. There has been enormous usage of high capacity electric motors in heavy load vehicles but a very small amount of work has been done in the sector of low load carrying vehicles like Hybrid electric rickshaw. Thus in this discussion we will be concentrating on Permanent Magnet DC Motor. In order to know whether the motor can be used in HEV performance analysis must be conducted, so we are analyzing the motor by applying different loads on it and observing the current absorbed, speeds at different torques and how the predicted values (Simulink) co-relate with the experimental values. These motors give an advantage to the hybrid Electric vehicles because they do not emit any tail pipe emissions and is environmentally friendly. Since safety and efficiency of the motor is also important we have conducted a Cfd analysis in Ansys Fluent to know whether the temperature of the motor is within the limits and thus conclude whether these motors are suitable for usage in HEV.
