The design bureau set a task to achieve a large braking torque (over 20kN) in a wide frequency range "without a power loss".
The task was solved by creating a loading device on the basis of a process box and an asynchronous machine. Combination of asynchronous machine of the braking device with the drive motor of the rig by shared variable frequency drive provides energy recuperation. The braking device has a forced cooling and greasing system.
