The invention relates to a method for compensating the oscillating torques in a pivoted bogie (1) of an electric tractive vehicle. According to said method, the oscillating torques in the driving motors of a tractive vehicle are compensated, said tractive vehicle having a plurality of driving motors (M1-M4) for propelling sets of wheels or individual wheels (2) in the corresponding chassis or wheel suspensions, more particularly in the pivoted bogies (1), wherein each driving motor (M1-M4) is multiphase and is divided into at least two partial systems (M1T1-M4T2). Each partial system (M1T1-M4T2) is comprised of individual coil groups (SG1-SG4) and each partial system (M1T1-M4T2) of a driving motor (M1-M4) is powered by a power converter (PWR1,PWR2) controlling the driving motors (M1-M4) by means of at least one drive control apparatus (5) in such a way that given oscillating torques are prevented, e.g. in the natural frequencies of the respective pivoted bogie, by detecting the corresponding natural frequencies of the pivoted bogie (1) through measurements and by storing the corresponding sets of pulse patterns in the drive control apparatus (5). |
