Improvement of heat transfer for DC motor windings

Temperature rise due to energy losses in the windings can reduce the performance of a motor as well as its service life. High temperature will damage the insulation on the windings and can eventually cause a short circuit that will permanently destroy the motor. Two different modifications which are...
