Coreless DC motors

Portescap’s Athlonix™ series of coreless DC motors satisfies demanding intrinsic safety application requirements with proprietary REE (Reduced Electro Erosion) technology.

Athlonix motors are said to provide higher power density, increased efficiency (approaching 90%) with lighter weight (15-53 grams depending on frame size) than comparable motors. The proprietary REE coil system reduces the effective inductivity of brush commutation by optimizing the mutual induction of the coil segments. Brush DC coreless motors feature low moment of inertia, no cogging, low friction and very compact commutation resulting in high acceleration, high efficiency, very low joule losses and higher continuous torque. They deliver maximum continuous torque ranging from 0.66 to 158.6 mNm, no load speed ranging from 11,000 RPM (8mm) to 5,500 RPM (35mm), and a motor regulation factor(R/K2) as low as .3 103/Nms.
