METHOD OF OPTIMUM REGULATION OF TRACTION ELECTRIC DRIVE OF SELF-CONTAINED VEHICLE WITH ASYNCHRONOUS TRACTION ELECTRIC MOTORS Russian patent published in 2015 - IPC B60L11/00 H02P21/00 

FIELD: engines and pumps.

SUBSTANCE: method of regulation of the traction drive can be used in traction asynchronous electric drives of self-contained vehicles, including pneumatic-tyre cars, tractors, and also locomotives. It ensures ICE functioning at maximum and medium characteristics in the modes of maximum cost-saving and distribution of traction efforts between active wheels of a vehicle at linear movement, and at small speeds - and on turns, similar to distribution of traction efforts in widely used and well proven differential drive. Changes of voltage and current feedback values are inversely proportional to the rotation speed of the generator. RPM regulation of each electric motor of the electric drive is implemented by means of setting of pre-calculated parameters (absolute sliding and current) in the function of rpm of electric motors ensuring the functioning of electric motors in the optimum mode. Meanwhile the channels of motor voltage frequency pre-setting have no feedback.

EFFECT: ensuring of ICE operation in the mode of maximum cost-saving.
