Linear electric motor (ironless, synchronous, brushless)
66 - 646 N | BLMC Series
Aerotech
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.
