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