FIELD: transport.
SUBSTANCE: mine vehicle contains three-phase and multi-phase traction electric motor. Nominal power of traction motor is determined based on certain driving speed and load, herewith, traction motor has nominal torque at certain speed of rotation. Traction motor is connected with driving wheel of mine vehicle using constant gear ratio. Traction motor rotation speed control is implemented by means of motor controller. This traction motor is actuated in delta connection with some driving speed and if necessary traction motor torque is increased at lower driving speed as against certain driving speed by means of traction motor operation in wye-connection and at the same time short traction motor overloading.
EFFECT: providing nominal torque at preset rotation speed while using constant gear ratio.
