WhatsApp: +86 18838072829In my opinion, current imbalance on motors of a twin Pinion Mill Drive train is caused by inaccurate load sharing. Power supply to the motor has no effect as it is passive and power is drawn as needed. Since this is a WRIM and LRS set up (no VSD with active load sharing or Quadramatic) the motors rely on natural load sharing.
