2195 N (493.5 lb)

• Special magnet options available for increased force output

• 114.1 mm high x 50.8 mm wide cross section

• Follows the 2011/65/EU RoHS 2 Directive

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 coil 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 is shown with Aerotech’s linear motor line.

The BLMH can be driven using standard Aerotech

brushless amplifiers and controllers to provide a

complete, integrated system.
