Abstract
A multi-drive system includes a plurality of drive motors, a variable frequency drive coupled to each drive motor, a drive head coupled to each drive motor, a drive ring couplable to the rotatable drum, the drive ring engageable with the plurality of drive heads, and a controller coupled to the plurality of variable frequency drives. A method of operating a multi-drive system includes sending an initial speed command to each variable frequency drive, reading a nominal operating torque of each drive motor, computing a first total torque of the system and a first reference torque for each drive motor, sending a first adjusted speed command so a first applied torque is substantially equivalent to the first reference torque; and adjusting the speed command if a drive motor is disengaged from the multi-drive system.
