Virtue

Our tubular motors emit minimal noise when in operation, are easy to conceal, compact in size and a whisk to install.

General Design

Tubular motors are designed to fit within a rotating axle and thus appear tubular in appearance. They general comprise a metal or plastic tube with a drive wheel or flange at one end. At the most simple level the tubular motor comprises an AC electric motor that drives a series of planetary gear trains mounted into the tube.

The most common form of limit stop are mechanical limits that are set and remembered by using pulse counting on an encoder wheel inside the motor. In a typical application this requires the installer to set the limits by manually running the motor to the extreme limits and pressing a button on the motor, or perhaps on the remote control.

Typical Application

In a typical application the tubular motor is fitted within an axle. It is fitted such that the 'tube' of the tubular motor cannot rotate with respect to the axle that it is fitter within. The drive wheel or flange usually includes a means of attachment to an axle, and is fixed such that the drive wheel cannot rotate with respect to the roller shutter. Thus when the tubular motor is powered the drive wheel does not rotate, but the 'tube' of the tubular motor does, resulting in the axle rotating.
