Review in thermal effects on the performance of electric motors

Thermal effects play an important role on the performance of electric motors for the applications in traction/propulsion systems. In these type of applications, there is a feedback loop as well as transients are involved. The torque speed characteristics of the electric motors are dependent upon the motor parameters such as armature/rotor resistance, stator resistance etc. The parameters are significantly affected by the temperature because change in temperature is very high in propulsion systems. As a result, the performance of electric motors used in propulsion systems is degraded. In this paper, the thermal effects on electric motors are combined at one place which is not done before. This will be quite helpful for the researchers of this area to study the thermal effects on the performance of electric motors collectively.
