Portescap, a Danaher Motion Company, has introduced Athlonix high-power density brush dc motors. These compact, high-efficiency endurance motors deliver unrivalled speed-to-torque performance in a compact lighter weight package (15-53 grams depending on frame size) with output power up to 9 watts. Athlonix motors feature an energy efficient coreless design with an optimised self-supporting coil and magnetic circuit, which delivers maximised power density and sustained endurance over the life of the motor. They are available in 12, 16 and 22 mm frame sizes.
“Athlonix motors are powered by a proprietary self supporting coil, whose design optimisation flows from more than 70 years of Portescap research and design. The result is maximised magnetic flux and turn-density for a given diameter, within the Athlonix motor platform,” says Udayan Senapati, brush dc product line manager at Portescap. “In contrast, typical self supporting coils have inherent turn-density limitations that affect the magnetic flux density in the magnetic circuit, which further limits power output and endurance of the motor,” he says.
The optimised coil design leads to a low motor regulation factor with energy efficiency approaching 90%, depending on the motor load conditions. With such high efficiency, users benefit from increased performance over the life of the motor, in a more compact and lighter weight package. Additionally, less power-draw helps facilitate reduced cost of ownership with increased value-in-use for the end-user.
With maximum continuous torque up to 16.5 mNm and superior angular acceleration, Athlonix motors deliver high throughput by quickly and efficiently accelerating to the desired speed. As a result, they are ideally suited for use in automation applications such as medical analysers and electronic assembly that require constant pick-and-place operations during machining, assembly and scanning. Their endurance and high performance, energy efficient operation also makes them well suited for use in medical pumps, secure door locks, watch winding mechanisms and robotics, among others.
