Design Features

The BLMH series U-channel brushless linear servomotors offer over 70% greater continuous output force in the same physical envelope than similar models from other manufacturers. BLMH series motors feature a high-efficiency magnetic circuit design that provides continuous force ratings to 548.8 N (123.4 lb) and peak forces to 2195 N (493.5 lb). This extremely high level of performance can be enhanced with special magnet options that increase force further, thereby lowering heat generation.

BLMH series linear motors are direct drive and consist of a noncontact forcer assembly with Hall-effect devices, a thermal sensor, and U-channel magnet track. This design eliminates magnetic attraction to allow for extremely smooth motion and very tight velocity and position control. In addition, backlash, windup, wear and maintenance issues associated with ball screws, belts, and rack and pinions are eliminated.

The BLMH series nonmagnetic forcer eliminates cogging and magnetic attraction to allow for extremely smooth motion and very tight velocity and position control. These linear motors are ideal for any application that requires high speeds with high loads. BLMH series linear motors are forgiving to align, easy to assemble, and keep the magnetic field well-contained. Magnet tracks are stackable for any travel length. They are also suited for industrial usage.

The BLMH can be driven using standard Aerotech brushless amplifiers and controllers to provide a complete, integrated system.
