maxon motor uk ltd is launching a new DC servo-motor to coincide with the Drives and Controls 2000 Exhibition - Featuring maxon's ironless winding system, the RE40 motor provides outstanding value in terms of performance, dynamics and installation size and forms part of a modular system that includes planetary gearheads and encoders.

The 150 Watt RE40 DC motor - which has an external diameter of 40mm and is 71mm long - is fitted with a strong Neodymium magnet and maxon's ironless rotor system made famous in successful space missions (see Plate 2).

The RE40 is exceptionally durable for a mechanically commutated motor thanks to the very low inductance of maxon's ironless winding. Other major benefits are maximum efficiency of up to 90 per cent, detent free operation, very low starting time constants of 4ms and high overload capacity. Three different windings are already available so that the best match can be found for any particular application.

Preparations are under way to combine the RE40 with a brake and to offer an "industrial version" where all electrical terminals with cable screw connections are fed into a terminal box, allowing the unit to meet the requirements of protection class IP54. These servo-drives are used widely in automation systems, aviation, medical technology and mechanical engineering.

Keith Ellenden, chief executive of maxon motor uk ltd said:

We recognise that Drives and Controls 2000 is one of the premier events in the industrial calendar which is why we always aim to unveil something a bit special. We believe that, with its outstanding performance and innovative design features, the RE40 will attract the interest of many designers and production engineers.
