Packaging is a booming technology, and new motion control products are continually being introduced to make it easier for design engineers to get the performance they want on packaging lines. Among the latest product introductions: a new gear motor, a new bipolar driver/controller, and a new drive nut.
Midwest Motion Products (www.midwestmotion.com) introduced a 12-volt DC gear motor for packaging applications. It's 2.8 inches in diameter and 5.6 inches long, with an 80 mm-square gearbox. The output shaft is 10 mm in diameter.
The motor has an 18:1 gear ratio and shaft output speed of 160 rpm. It's rated for 26 in lbs of continuous torque at 3.9 amps of current, and is capable of 70 in lbs of peak torque.
Meanwhile, RMS Technologies (www.rmsmotion.com) unveiled the R101 bipolar driver/controller. Itg's capable of output current from 0.2 to 2.5 amps/phase, with step resolution from full, .50, .25, and 1/8.
And, Amacoil (www.amacoil.com) announced the Model RS4 drive nut for backlash-free linear motion. The drive nut is available in seven sizes, and the nut can be used in vertical or horizontal applications. The shaft rotational speeds can be up to 10,000 rpm. Linear travel speeds range from 0.5 ft/second up to 4.0 ft/second. Axial thrust ranges from 22 lbs to 449 lbs.
The company installs Uhing rolling-ring bearings under pressure in the drive. There is a constant single point of contact between bearings and drive shaft. The result, the company says, is zero play when the shaft rotates.
