Airex™ Ironless Linear Motors
Airex's ironless linear motors utilize powerful permanent magnets and lack iron in their coils, reducing inductance and improving response times. They excel in precision applications, offering low heat rise and high bandwidth. The P-Series and C-Series motors feature high force density, compact designs, and superior performance. Airex motors are customizable, with options for mounting, cables, thermal sensors, and vacuum compatibility. These motors provide unmatched performance in direct drive systems, eliminating issues like backlash and wear.
Specifications Overview
P-Series
The P-Series is our workhorse, sporting our highest force density, superb electrical phase balance, flexible in-field electrical connection choices and the largest number of configurable options, resulting in motor implementations with the highest-degree of veracity.

Common Uses for Ironless Linear Motors
With Airex’s patented coil winding technology our linear motors are the ideal solution for actuators, precision stages, photonics platforms, semiconductor equipment, pick-and-place systems and inspection systems that require exceptionally responsive control at high bandwidths while simultaneously maintaining a low heat rise. Your solution may require an IRON core linear motor, utilizing high-temperature rare-earth magnets, from our P-Series or C-Series linear motors (all customizable).
Our motor is ideal in ultra-precision direct drive systems. The high intrinsic coil stiffness we employ eliminates backlash and windup inherent in other linear driven systems. Airex’s linear motors also eliminate the wear problems typically associated with ball-screws, belt drives and rack-and-pinion linear motion systems.
This expertise grants precise control at low velocity and superior point-to-point settling times. Our manufacturing method ensures precision placement of the conductors with minimal end turns, providing the highest slot fill in the industry as well as the best thermal path available on the market. High-energy, rare earth magnets complete the magnetic circuit.
