Aerotech Linear Motors www.aerotech.com Dedicated to the Science of Motion

Aerotech Linear Motors Aerotech's "U-channel" brushless linear servomotors are ideal for robots, actuators, positioning stages, fiberoptics/photonics alignment and positioning, assembly, machine tools, semiconductor equipment, electronic manufacturing, vision systems, and in many other industrial automation applications that require high-speed/high-accuracy motion. Aerotech linear motors are direct drive and are available in two different configurations - "U-channel" and "flat" versions. The U-channel design consists of a noncontacting forcer coil and U-channel rare-earth magnet track. This...

BLMSC Series The BLMSC linear motor is Aerotech's smallest "U-channel" linear motor measuring only 37.5 mm x 22 mm in cross section. With a high power density and force output, the BLMSC is ideally suited for space-constrained applications requiring high-acceleration or high force output. The motor consists of a noncontact forcer coil assembly with thermal sensor, optional Hall-effect devices, and "U-channel" magnet track. The design eliminates backlash, windup, wear, and maintenance issues associated with ball-screws, belts, and rack and pinions. The moving forcer coil assembly is a...

BLMUC Series The BLMUC linear motor is an ultra-compact "U-channel" motor measuring only 52.0 mm x 20.8 mm in cross section, designed to provide high force in an ultra-compact package. The BLMUC is ideally suited for small load applications with tight space constraints such as a pick head on a pick-and-place machine, and low-mass, high-acceleration material handling machines. Notes: 1. Performance is dependent upon heat sink configuration, system cooling conditions, and ambient temperature. 2. All performance and electrical specifications ±10%. 3. Values shown @ 100°C rise above a 25°C...

BLMC Series 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. 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...

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. The BLM series nonmagnetic forcer eliminates cogging and magnetic attraction to allow 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. BLM series linear motors are forgiving to align, easy to assemble, and keep the magnetic field well-contained. Magnet tracks are stackable for any travel...
