Process Control Corp., Atlanta, is offering a new drive/gearmotor package for its auger-based, continuous loss-in-weight feeders and blenders. The X-Series blenders and AFG/PF feeders previously used a PWM drive and a permanent-magnet DC gearmotor to turn the metering auger. The new gearmotors are both brushless and encoderless for far superior reliability and performance and longer life. With more torque and a much wider speed range, the new gearmotors require only two power/gear ratio combinations to cover the required rpm range for the company’s line of blenders and feeders, vs. eight power/gear-ratio combinations for the permanent-magnet gearmotors. The new package is fully compatible with PCC blenders and feeders already in service.
