摘要：
Performance of a wheel loader with permanent-magnet-synchronous-electric-wheel driven technologies was studied by theoretical and experimental methods. Theoretical analysis shows that electric wheels of the loader, based on field-weakening control algorithm, can be well adapted to the traveling, braking, traction and steering conditions with cooperative and efficient work. Experiments on an improved ZLM15B wheel loader under the above driving conditions were carried out on the level cement road. Experiment results further validate that the traveling and traction efficiencies between permanent-magnet-synchronous-electric wheels are both better than 90%, which can well adapt differential steering with good consistency of the speed and the torque between electric wheels under braking.
