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 highthroughput applications,
BLMC series motors are direct drive consisting of a noncontacting
forcer coil and “Uchannel” 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.
