How to improve the working efficiency of the dc motor controller

Today small make up teach you how to improve the work efficiency of dc motor controller, to make it wider interests. 1. Can through reduce the copper loss and iron loss, increase the size of the dc motor controller, on the basis of the maintain voltage and load, reduce each slot number of turns, and increase the wire diameter. 2. If it has a brush dc motor controller, can through to replace copper commutator with carbon commutator to improve work efficiency. 3. If it is a brushless dc motor controller, can through the rotor, the use of high-performance permanent magnet materials to improve the work efficiency. 4. Can be controlled by adjustment of the permanent magnet dc motor control circuit of the controller, to improve the work efficiency. These are several methods to improve the efficiency of dc motor controller, hope to help everyone.
