Iron Core Linear Motors
Airex produces iron core motors using the same patented coil technology utilized in our toothless design. These motors are used in applications where a bearing preload is beneficial to the overall system. These motors are configured as single sided where the coil assembly is supported over the magnet track. The iron core motor is a direct drive system that eliminates backlash, windup and wear associated with ball-screws and rack-and-pinion type drives.

Unmatched performance
Airex manufacturing method for coils ensures precision placement of the conductors to provide the highest slot fill in the industry. These elements provide an exceptional thermal path for heat to dissipate out of the coil. Our coil design maintains a constant and consistent attractive force, and provides very low levels of cogging and saliency as compared to other systems. The built-in preload allows longer motion platforms to be designed for preload in one direction for rigidity while moving over long spans.
High-temperature rare earth magnets are used in the creation of the Airex magnet plates. These modular plates allow for the construction of very long magnet tracks. The steel components and magnets are nickel plated for a long, corrosion-free life.
These motors are ideal for producing high forces in point-to-point and constant velocity applications. The motors feature fast point-to-point settling times — not typically found in our competitor’s motors.
