Replaces existing single speed and two speed dumper controllers with a true four quadrant adjustable speed controlled torque drive system.
Benefits:
Provides controlled acceleration and deceleration which softens the impacts that occur during speed changes and at the beginning and finish of the dump/return cycle.
Minimizes brake wear in that the stopping of the dumper is accomplished by regenerative motor torque. Dumping cycle can be decreased by increasing motor speed without changing gearing. Also permits an initial slow speed dump of the first car when the hopper is still empty.
