Linear electric motor (ironless, synchronous, brushless)
173 - 1 590 N | BLM Series Aerotech

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.
