www.aerotech.com BLM Series Linear Motors 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. BLM series motors are direct drive and consist 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 noncontact design of the forcer and magnet track results in a maintenance-free system. The compact moving forcer coil assembly contains Hall- effect devices, and a thermal sensor, and is constructed of High output force in an 86.4 mm x 34.3 mm cross section Continuous force to 397.6 N (89.4 lb); peak force to 1590.4 N (357.5 lb) High-energy rare-earth magnets used in magnet tracks for high acceleration capability Non-magnetic forcer coil provides high force with zero cogging for super-smooth velocity and position control Follows the 2011/65/EU RoHS 2 Directive 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, BLM motors are available with special high-power magnets that can increase output force. The BLM 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. 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 length. They are also suited for cleanroom use as they produce no particulates. The BLM can be driven using standard Aerotech brushless amplifiers and controllers to provide a complete integrated system. The BLM is shown with Aerotech’ s linear motor line.

www.aerotech.com BLM Series ORDERING INFORMATION Integration (Required) Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system. -TAS Integration - Test as system Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration. -TAC Integration - Test as components Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
