Portescap nuvoDisc(TM) Flat Brushless DC Motors Maximize Speed while Minimizing Size and Vibration in Rigorous Medical and Automation Applications

Ultra-compact package delivers unique performance and quality-of-use benefits to device manufacturers and end-users WEST CHESTER, PA - Portescap, a Danaher Motion company, introduces nuvoDisc(TM), an innovative family of flat brushless DC miniature motors. With an incomparably small footprint (32Mm diameter and 11.7Mm length), nuvoDisc is engineered specifically for markets where miniaturization is key and is ideally 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% shorter and 90% lighter than conventional flat motors, Portescap's nuvoDisc technology allows engineers even greater ability to miniaturize their applications without compromising performance. Offering speeds of up to 50,000 rpm and mechanical power output of up to 30 W(10mNm of maximum continuous output torque), nuvoDisc delivers the highest efficiency among all miniature DC motors. Moreover, nuvoDisc reduces power supply requirements by drawing less current, which minimizes generated heat. "This product is the result of years of experience in the respirator and barcode reader industries, and is engineered to bring benefits to OEMs and end-users alike," explains Jim Munley, Business Unit Director for Brushless DC Technologies at Portescap. "Manufacturers and marketers of battery-powered portable and hand held devices will benefit from a smaller, lighter, and high-efficiency solution resulting in a significant competitive advantage over conventional flat motor technologies. Similarly, end-users will benefit from superior comfort and improved portability, while having greater peace of mind resulting from increased efficiency and smoother operation," adds Munley. nuvoDisc delivers quick design integration and mechanical installation, and superior continuous speed when compared with conventional flat motors. nuvoDisc's brushless design eliminates mechanical wear to maximize reliability, while high performance ball bearings provide excellent life span. nuvoDisc complements Portescap's brushless DC motor family that encompasses the 16Mm BH, 22Mm BH, and the 30Mm BH brushless DC motors in various stack lengths.
