Stannah Head Office

Our client, Stannah, spends a good deal of their time on fostering innovation and continuous improvement to deliver the best quality products, flexible solutions and superior service, helping over 600,000 people rediscover their independence at home, saving energy for more enjoyable things, like socialising with their children and grandchildren.

To meet the most stringent requirements in the industry and exceed them, Stannah is testing third-party motor/gearbox units to be able to understand their performance, like torque, speed, thermal characteristics, current and voltage, etc.

Previously, they were using a torque arm, suspending various weights to apply the required torque to the motor being tested. However, this method proved to be imprecise and they needed a more accurate solution. Better accuracy would not only provide them with a big advantage when discussing test results with third parties but significant improvement of the stairlift efficiency. As an alternative, the team decided to build a dynamometer, to enable testing of every parameter of motor performance. One of the team members suggested using a rotary torque sensor, to give the critical accuracy they needed and suggested using a Datum Electronics product due to favourable previous experiences.

After researching various purchasing routes, Stannah’s team felt that personal recommendation was the most compelling reason to buy one of our units as they also wanted to have support from a local company, in the event they required assistance in setting up and using the torque sensor. Therefore, they made a final choice in favour of our Datum M425 rotary torque sensor and began much-anticipated testing.


Using the right motor/ gearbox for the stairlifts is crucially important to improve their efficiency, enhance their performance and make them the best value for money. Highly accurate test results have led to increased productivity, which has a positive impact on employees, customers, suppliers, the environment and the local communities in which the business lives. And it’s truly difficult to put a price on it.
