Aerotech BLMX Series Linear Motors

Design Features

• 49% greater continuous output force in the same physical

envelope than competitive models

• Continuous force to 1063 N (239 lb); peak force to 4252 N

(956 lb)

• 152.0 mm high x 50.8 mm wide cross section

• Special magnet options available for increased force output

• Follows the 2011/65/EU RoHS 2 Directive

The BLMX series “U-channel” brushless linear servomotors

offer over 49% greater continuous output force in the

same physical envelope than similar models from other

manufacturers.

BLMX series motors feature a high-efficiency magnetic

circuit design that provides continuous force ratings to

1063 N (239 lb) and peak forces to 4252 N (956 lb). This

extremely high level of performance can be enhanced with

special high-power magnet options that increase force

output.

The BLMX 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.

The BLMX is shown with Aerotech’s linear motor line.

Linear Motors

BLMX linear motors are direct drive and consist of a

moving 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 BLMX 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 applications demanding the

ultimate in force output. BLMX 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. These motors are well-suited for industrial

applications.

The BLMX can be driven using standard Aerotech brushless

amplifiers and controllers to provide a complete,

integrated system.
