Aerotech BLMC Series Linear Motor

Designed for high force in a compact package




Aerotech's "U-channel" BLMC series compact linear motors are only 57.2mm x 31.8mm and are designed for high force in a compact package.


Ideal for both high-accuracy positioning and high-throughput applications, BLMC series motors are direct drive and consist of a noncontacting forcer 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.



  • Compact size for tight space constraints; 57.2mm x 31.8mm cross section
  • Continuous force to 184.0N (41.4lb); peak force to 736.0N (165.5lb)
  • Non-magnetic forcer coil provides high force with zero cogging for super-smooth velocity and position control
  • Optional cooling for higher rms force
  • Follows the 2011/65/EU RoHS 2 Directive

The compact forcer 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, BLMC motors are available with special high-power magnets that can increase output force.


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