Traction drive active pipe carrier trailer

The article describes the electric drives of the active trailer, which is part of the pipe carrier for the transport of large diameter pipes, required for laying oil and gas pipelines in rough terrain. With the help of electric drives the throughput of pipe carriers on marshland significantly increases and it is easier to control them. The above advantages appear if the trailer we use driving wheels, and a single-stage kinematic scheme of the drive. At the same time highlights the fact that the capacity of the electric drive will be 20-25 % of the rated power of the main truck, with an extended range of the speed control. The solving of this problem is based on the method developed by Professor Filatov for electric drives of the cold rolling mill winders. The method involves a dualband torque control. But this approach requires the use of electric drives with high torque overload (up to 10 times of the rated torque). The field regulated reluctance machine provides such overloads. Finally, the paper suggests techniques to choose the rational ratio of the quantities of the torque control subbands.
