Motors suit miniature applications

Edited by the Engineeringtalk editorial team Oct 2, 2007

A high-speed slotless design significantly reduces vibration and eliminates cogging to provide smoother operation and better accuracy for maintaining a stable speed.

Portescap has released the nuvoDisc range of flat brushless DC miniature motors.

It has a small footprint, measuring 32mm in diameter and 11.7mm in length.

The nuvoDisc is engineered for markets where miniaturisation 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.

The 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.

Portescap's nuvoDisc technology provides engineers with a greater ability to miniaturise their applications without compromising performance.

It offers speeds of up to 50,000rev/min and a mechanical power output of up to 30W.

Moreover, nuvoDisc reduces power supply requirements by drawing less current, which minimises generated heat.

Jim Munley, Business Unit Director for Brushless DC Technologies at Portescap said "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".

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 maximise reliability, while high-performance ball bearings provide excellent life span.
