ironless linear motor / brushless / DC

The BLMH series "U-channel" brushless linear servomotors are designed to offer over 70% greater continuous output force in the same physical envelope than similar models from other manufacturers. BLMH series motors are designed with a high-efficiency magnetic circuit to provide continuous force ratings to 548.8 N (123.4 lb) and peak forces to 2195 N (493.5 lb). The extreme high level performance is enhanced with special magnet options which further increases the force thus lowering heat generation. BLMH series linear motors are direct drive that are composed of a noncontact forcer assembly with Hall-effect devices, a thermal sensor, and "U-channel" magnet track.

The design eliminates magnetic attraction that enables extremely smooth motion, very tight velocity and position control and additionally eliminates the backlash, windup, wear and maintenance issues associated with ball screws, belts, and rack and pinions. he BLMH series nonmagnetic force eliminates cogging and magnetic attraction to ensure an extremely smooth motion
