Design Features

  • 70% greater continuous output force in the same physical envelope than competitive models
  • Continuous forces up to 548.8 N (123.4 lb); peak forces to 2195 N (493.5 lb)
  • Special magnet options available for increased force output
  • 114.1 mm high x 50.8 mm wide cross section
  • CE approved, follows the EU 2015/863 RoHS 3 directive

BLMH series linear motors are direct drive and consist of a noncontact forcer assembly with Hall-effect devices, a thermal sensor, and "U-channel" magnet track. This design eliminates magnetic attraction to allow for extremely smooth motion and very tight velocity and position control. In addition, backlash, windup, wear and maintenance issues associated with ball screws, belts, and rack and pinions are eliminated.

The BLMH 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 speeds with high loads. BLMH 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 industrial usage.

The BLMH can be driven using standard Aerotech brushless amplifiers and controllers to provide a complete, integrated system.

Integrated (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.

Option Description
-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.
