Motor Technology, working in partnership with Motor Power Company, has designed a customised torque servomotor that will act as a current generator on a range of vertical-axis wind turbines.

The vertical-axis turbine is a wind power generation concept designed by Quiet Revolution.

The thinking behind it is to produce turbines that operate quietly and efficiently in an urban environment, or, more specifically, at the point of power usage.

Conventional wind turbines are generally unsuitable for urban locations, if for no other reason than the noise they produce while operating.

Quiet Revolution’s turbines can be located on rooftops, car parks, near classrooms, homes and other noise sensitive locations.

In order to meet Quiet Revolution’s specifications, an SKA DDR direct drive motor was redesigned with a special electrical winding that could be combined with the electronic control and would eliminate any mechanical noise during operation.

Another key factor was keeping maintenance to a minimum; so the bearings, lubricant and lubrication techniques were chosen on the basis of thorough research and testing.

Additionally, the servomotors were designed to have a lifetime of 25 years, despite the fact that mechanical protection had to be limited in order to avoid aggravating the inertia of the system.

The SKA DDR motor with its hollow passing shaft is integrated directly below the vertical triple-blade propeller.

Its job is to act as a current generator driven by the blades that are turned by the power of the wind.

The motor also drives the turbine during start up when it is said to be ‘catching’ the wind.

Motor Technology

For over 25 years Motor Technology has supplied servo and automation components, including motion controllers, servo drives and motors, feedback devices, precision gearboxes and couplings, all backed by our sales and technical support.

Our in-house design team has worked with some of the biggest names in industry to design and install drive and control systems, and provide solutions for everything from the relatively simple right the way through to the most complex and demanding of applications.

Catering to maintenance engineers we also offer a spare parts and in-house repair service. Whether you are looking for a replacement product or require an equivalent component, we are here to assist you. Drawing on our experience and knowledge of the servo and motion control market we can also source products from outside our standard range. Very often we can even replace out-of-date components by sourcing compatible products manufactured under license.
