Engineers designing linear motion systems often face high detent force, excessive core losses, and poor thermal performance in conventional linear stator designs. For drone stabilization actuators and high-speed linear BLDC motors, even minor inefficiencies degrade precision and response. Reenives solves this with advanced laminated linear stator cores: ultra-low detent force (≤1.2N), high saturation flux density, and precision epoxy coating for consistent insulation. Our linear stator technology improves force density by up to 20%, enabling smoother, more efficient linear motion.

⚙️ What is a Linear Stator Core?

A linear stator core is the stationary part of a linear motor or linear actuator, constructed from stacked silicon steel laminations with open slots for windings. Unlike rotary stators, linear stators feature a flat or curved geometry that generates linear thrust via electromagnetic interaction with a moving magnet array. For drone applications, linear stators are critical in gimbal actuators, flight control surface drives, and VTOL trim mechanisms. Reenives manufactures linear stator cores using 0.2mm / 0.35mm non-grain oriented electrical steel with high-precision stacking (tolerance ±0.02mm) and optional epoxy powder coating for harsh environments.
