PCC (www.process-control.com) has announced the launch of its latest gearmotor/drive package for its auger based, continuous loss-in-weight blenders and feeders. To rotate the metering auger, the AFG/PF feeders and X-Series blenders previously integrated a permanent DC gearmotor and a PWM drive. The company has developed a new breed of motor drives that would control its previous permanent magnet motors and its latest generation of brushless DC motors.
Encoderless and brushless, the new gearmotors offers far more superior performance, reliability and a longer service life as against the old model. Unlike the eight gear/power ratio combinations of the previous permanent magnet gearmotors, the new gearmotors only needs two gear/power ratio combinations to cover the required range of the RPM for the feeders and blenders. The company’s latest gearmotor/drive is 100 percent compatible with PCC feeders and blenders already in service and has already started shipping new systems in April.
PCC General Manager, Dana Darley, said that the company’s new auger drive package represents a significant advancement in the reliability and performance of PCC’s premium line of gravimetric feeders and blenders.
He added that the company is so confident of this latest system that it is considering giving three-year warranty on both the gearmotor and the drive, whether it was purchased as a spare part, an upgrade or on a new feeder or blender.
