Aerotech’s “U-channel” BLMC series compact linear

motors are only 57.2 mm x 31.8 mm and designed for high

force in a compact package.

Ideal for both high-accuracy positioning and high

throughput applications, BLMC series motors are direct

drive consisting 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 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, 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.
