BLMF Series (Steel Laminated) Linear Motors
The BLMF series linear motors are designed to provide a lower cost and lower profile alternative to conventional linear motor applications. The BLMFS series utilizes steel laminations to produce more force for a given forcer coil length, making it ideal for high speed point-to-point motion. The attraction force can also be used as a bearing pre-load.

Design Features
- Slotless magnetic forcer to improve force production with reduced cogging
- Continuous force to 159.4 N (35.8 lb); peak force to 637.7 N (143.4 lb)
- Unlimited travel length by stacking magnet tracks
- High-energy, rare-earth magnets used in magnet track for high acceleration capability
- CE approved, follows the EU 2015/863 RoHS 3 directive
The forcer assembly contains Hall-effect devices and a thermal sensor, and is a compact, reinforced ceramic epoxy structure.
Offering high peak forces in its standard configuration, BLMF motors are available with higher-power magnets that can be used to increase output force.
These linear motors are ideal for any application requiring high levels of positioning resolution and accuracy. Tracks are stackable for any travel length. The BLMF linear motors are also for cleanroom use as they produce no particulates.
The BLMF can be driven using standard Aerotech brushless amplifiers and controllers to provide a complete, integrated system.

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.
| 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. |
