The obvious solution is to use more pinions, say, four per mill, with each pair coupled to the output shafts of a special single-input/double-output reducer — two reducers and two motors per mill. The problems of load division remain in this case, both in the reducers and in the motors. Another solution is to use the so-called "gearless drive."

Dual high speed slip ring motors can be used to drive through gearboxes to dual pinions. Load sharing is inherently possible but not very accurate. This can lead to load swings between the two motors and result in accelerated gear wear. To overcome these conditions, a permanent slip resistor may be installed between the two rotors.
