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