High output force in an 86.4 mm x 34.3 mm
Continuous force to 397.6 N (89.4 lb); peak
force to 1590.4 N (357.5 lb)
High-energy rare-earth magnets used in
magnet tracks for high acceleration capability
Non-magnetic forcer coil provides high force

and position control
Aerotech’s “U-channel” BLM series linear motors are 86.4
mm x 34.3 mm in cross section and have proven ideal for
both high-accuracy and high-throughput applications.
BLM series motors are direct drive and consist of a
noncontacting forcer coil and “U-channel” rare-earth
magnet track. This design eliminates backlash, windup,
wear and maintenance issues associated with ball screws,
belts, and rack and pinions.
The noncontact design of the forcer and magnet track
results in a maintenance-free system.
The compact moving forcer coil assembly contains Hall-
effect devices, and a thermal sensor, and is constructed of
reinforced ceramic epoxy. This ironless design eliminates
eddy-current losses that otherwise would limit speed and
produce additional heat. For highest rms force, optional air
cooling is available. Offering high peak forces in its
standard configuration, BLM motors are available with
special high-power magnets that can increase output force.
The BLM 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 levels
of positioning resolution and accuracy. BLM 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 cleanroom use as they produce no
The BLM can be driven using standard Aerotech
brushless amplifiers and controllers to provide a
complete integrated system.
The BLM is shown with Aerotech’s linear motor line.
