<p>PURPOSE:To prevent the production of a torque difference between a right side wheel and a left side wheel for an electric motor vehicle by increasing the output frequencies of the first and the second inverters for respectively driving the first and the second induction motor for driving the right side and the left side wheels respectively higher than the rotating frequencies of the respective induction motors. CONSTITUTION:The first and the second inverters 7, 8 for respectively driving the first and the second motors 3, 4 for respectively driving wheels 1, 2 disposed at the left side and the right side with respect to the moving direction of an electric motor vehicle are provided in the vehicle. The first and the second inverters 7, 8 supply respectively the output currents having frequencies f01, f02 higher than the rotating frequencies f1, f2 respectively of the motors 3, 4 respectively detected by respective revolution speed detectors 5, 6 to the motors 3, 4 respectively. Thus, it can prevent the production of a torque difference between the right side wheel and the left side wheel due to their inner wheel difference.</p> |
