The 5020-4 direct-drive linear tubular motor provides 750-lb peak force (with
30A excitation) over a 2- to 12-inch stroke range in 2-inch increments. Targeted
at pneumatic-, low-end hydraulic-, ballscrew-, cam-, belt-, and pulley-driven
applications, the compact linear servomotor develops a maximum frequency
(accelerating and decelerating) response of 60 Hz over a 1/8-inch distance.
A stack of ring magnets arranged in alternating polarity forms a magnetic
shaft, the only moving part, that rides on sliding-contact bearings housed in
the endbells. The shaft is suspended in, and passes through, a column of current
carrying coils held in slots along an iron core.
"Because the coils act on the entire (360-degree) surface of the moving
member, we get higher force per volume than flat- or channel-type linear
motors," says Chuck Schultz VP of sales and marketing. "And it's integral
bearing makes it easier to assemble."
