Portescap Intros Ultra-Compact Flat Brushless DC Motor
Flat brushless DC motor.
West Chester, PA — Portescap, a Danaher Motion company, is introducing nuvoDisc, described as an innovative family of flat brushless DC miniature motors. With a very small footprint (32mm diameter and 11.7mm length), nuvoDisc is engineered specifically for applications where miniaturization is key and is especially suited for space-constrained applications such as portable respirators and barcode scanners.

A high-speed slotless design significantly reduces vibration and eliminates cogging to provide smoother operation and better accuracy for maintaining a stable speed compared with conventional miniature flat motors. nuvoDisc also eliminates the bulk and limited portability inherent in other types of DC motors. A slotted design is available for applications that require detent torque, such as Damper Control in the HVAC industry.

Over 75 percent shorter and 90 percent lighter than conventional flat motors, the new technology allows engineers even greater ability to miniaturize applications without compromising performance. Offering speeds of up to 50,000 rpm and mechanical power output of up to 30 watts (10mNm of maximum continuous output torque), nuvoDisc reportedly delivers the highest efficiency among all miniature DC motors. Moreover, it reduces power supply requirements by drawing less current, which minimizes generated heat.

According to the company, the product delivers quick design integration and mechanical installation, and superior continuous speed when compared with conventional flat motors. Its brushless design eliminates mechanical wear to maximize reliability, while high performance ball bearings provide excellent life span. The new motor complements the company's?s brushless DC motor family that encompasses the 16mm BH, 22mm BH, and the 30mm BH brushless DC motors in various stack lengths.
