Maximum-Efficiency DC-Motor Project for Electric Vehicles. Final Report

摘要

Innovations to the operation of the typical direct current motor were made and included: an electronic circuit to generate a low-level voltage circulation, an interface circuit capable of an 800% voltage amplification and a 3000% current amplification, and a specially modified motor containing three additional brushes. The efficiency of the motor is maximized by an electronic circuit that aritificially rotates the magnetic field around the armature at low RPM so that the motor is running at near peak efficiency virtually all the time.
