SKF has signed a Memorandum of Understanding (MOU) with Proteus Marine Renewables (PMR) and GE Vernova’s Power Conversion business. The MOU sets out a framework for a potential alliance to supply tidal turbine generation systems (TTGS) to developers of tidal arrays for commercial, multi-megawatt tidal stream projects. An initial focus will be the supply of a minimum 59MW to MeyGen PLC (MeyGen) at its site in Scotland, the largest tidal stream facility in the world. 

Rotork Controls has established a global reputation for robust and reliable valve actuators, operating in some of the world’s most demanding and critical applications. Thorough testing of the motors used in the actuators is one of the keys to this assured performance, with TorqSense transducers from Sensor Technology playing a vital role in the test process.

I think I spend more time talking about ball bearings today than at any other time in my career. Ball bearings have always had a large place in automotive, but not typically in high demand positions—other than a few niche areas. High demand positions, such as axles and planetaries, were typically reserved for tapers, needles and cylindricals. The landscape is changing quickly.

Heat is also generated in an e-motor, sometimes quite a bit. In demanding applications, the motor electronics cause the power to be throttled or even shut down completely. But there is another clever way to protect an electric motor from overheating without losing power: using a thermally conductive casting resin as a heat transfer medium. The principle can also be called a static solid cooling system.
