- Aerotech's smallest linear motor: 37.5 mm x 22 mm cross section
- Continuous force to 27.7 N; peak force to 110.9 N
- Non-magnetic forcer coil provides high force with zero cogging for super-smooth velocity and position control
- Ideal for space-constrained applications
- Follows the 2011/65/EU RoHS 2 Directive
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 compact, reinforced ceramic-epoxy structure. The ironless design eliminates cogging and eddy-current losses that otherwise would limit speed and produce additional heat.
These linear motors are ideal for any application that requires high levels of positioning resolution and accuracy. BLMSC 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 BLMSC can be driven using standard Aerotech brushless amplifiers and controllers to provide a complete integrated system.

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. This is typically used for spare parts, replacement parts, or items that will not be used or shipped together (ex: stage only). These components may or may not be part of a larger system.
