These are designed to allow the flexibility to iterate designs with the eventual certainty required for production parts. Precision Microdrives Capabilities and Competences Precision Motor Testing and Motor Testing Services When we started PMD there were no commercial testing machines available, so we built our own. Ever since we’ve continued to develop new motor testing machines & procedures each year. Fast forward to today and we now have the most extensive testing facilities in the world for sub 40mm diameter motors, gear motors and vibration motors. These are used to validate motors through specification stages and during manufacturing. We also test motors as a service, provide easy to read reports and assist customers with their interpretation. Motor Customisation, Design, and Manufacturing To be useful motors need to be integrated with other parts, such as housings or couplings . We routinely develop and produce complete assemblies, from motors with customised leads or connectors to complete electromechanical mechanisms and integrated control electronics. We will support and guide you through the specification stages from prototype to signing-off for mass production. Competent and Dependable Supply Chains for Production Most of the worlds miniature motors are made in Asia, and you need engineers on the factory floor who can maintain the Western values of “doing things right” whilst supporting the Asian values of “getting things done”. As a customer you are supported by expert eyes, right at the heart of the manufacturing process where it is needed: On the ground in the UK, Hong Kong, and China. Quality Engineers on the Ground and Local Engineering Teams The nature of our business is to confidently produce and supply motors ‘On time & To spec’. Our customers benefit from our certified ISO 9001 quality systems, reliable motor production infrastructure, and experience. We have a core competence in helping customers design out over-specified and expensive European drives, with more cost-effective, adequately specified, and verified Asian alternatives.
