PURPOSE:To increase the tensile force and brake force of an electric railcar by controlling induction motors of odd and even number axle positions by two sets of inverters in response to the axle load movement. CONSTITUTION:A body 1 is supported by two sets of 2-axis bogie truck frames 2, 3. Induction motors 21, 23 for driving Nos. 1, 3 shafts 11, 13 of odd number counted from the head of the moving direction of driven wheels 11-14 of truck frames 2, 3 are connected with an inverter 8, and induction motors 22, 24 for driving Nos. 2, 4 shafts 12, 14 of even number counted are connected with an inverter 9. A controller 10 generates a command for generating motor torque smaller by the prescribed rate than the other of two sets of the inverters 8, 9 in response to the acceleration and deceleration of an electric railcar in the moving direction. |
