maxon motor launches innovative 040 mm,150 watt high power DC motor

Keywords maxon motor uk ltd, Servo-motors

maxon motor uk ltd launched a new DC servo-motor to coincide with the Drives and Controls 2000 Exhibition. Featuring maxon's ironless winding system, the RE40 motor is thought to provide outstanding values 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.

The RE40 is said to be exceptionally durable for a mechanically commutated motor thanks to the very low inductance of maxon's ironless winding. Other major benefits claimed 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.
