Evaluation of DC machine armature winding temperature estimation using temperature measured on brush and bearing

The armature of a dc machine rotates inside the machine, making it expensive and complex for physical temperature instrumentation and visual thermography. A real-time temperature estimator using the temperature data measured on non-moving parts like the brush and bearing could be developed by determ...
