FIELD: agriculture; mechanical engineering.
SUBSTANCE: invention relates to agricultural tractors. Self-propelled machine electromechanical transmission comprises traction generator, internal combustion engine, a traction electric motor, side reduction gears, and control system. Traction electric motor has the number of stator and rotor teeth based on the number of phases the controller is changing. Traction-generator or electric motor is made with a combined independent electromagnetic and magnetoelectric excitation. Traction electric motor has a number of phases more than three. Controller changes the algorithm for switching the coils of these phases depending on the machine movement speed. Controller manages the traction-generator or power rectifier. Electromechanical transmission contains a liquid cooling system of a traction-generator or traction motor, or a power rectifier, or a controller. Windings of the traction motor stator are made with a coefficient of filling the grooves with copper more than 0.5.
EFFECT: range of stepless speed control is widening.
