CONTROL SYSTEM FOR ELECTRIC VEHICLE EQUIPPED WITH ENERGY SAVING TYPE DC MOTOR-GENERATOR

摘要

PROBLEM TO BE SOLVED: To omit an inverter by using a DC motor as a driving motor, and prevent the lowering of generating capacity while saving energy by applying a brushless system. SOLUTION: An energy saving type DC motor-generator 12 with flywheel effect (the use of resiliency of a high-power magnet and the combined use of flywheel effect by ballast balls) added, and flywheels 10, 11 are arranged on a driving main shaft. A reduction gear of a low reduction gear ratio is provided at the output shaft end of the driving main shaft to increase torque, and sensor (rotation and temperature) output is controlled through a control means using IC to attain economical travel.
