Direct motors

Engine construction with passion

As a motor manufacturer, AS accompanies every step of the design process for a drive unit – whether for modernisation or for a new-build. Starting with an analysis of the drive requirements, production of a requirement specification and design on the CAD system through to simulation of the drive and integration of it in commonly used control systems

The engine manufactory

The complete production of these machines takes place at AS. Sheet metal packages, winding systems and the rotors are extensively tested in the final assembly of the drive and the final test run of the quality assurance. In order to withstand the unavoidable overvoltage peaks of modern frequency converters even at high temperatures, AS uses a particularly stable and highly resilient insulation system. While all machines meet at least the requirements of the thermal class H=180°C, all motors can be approved for operation on 690VAC converters with 1000VDC DC link. The direct motors from AS are characterised by extreme durability (even on modern, particularly fast-switching frequency converters).

Variants

The mechanical connection of the machines is either via solid or hollow shafts and can also be adapted to customer-specific dimensions. All FlexoDirect® motors can be supplied as foot or slip-on versions. With this direct drive technology, efficiencies of over 97% can be achieved. In contrast to IEC motors, these values are achieved over a much wider speed range. The synchronous machine offers significant advantages here as a low-speed, high-pole machine.

Application examples in the paper industry

AS offers direct drives for the entire paper production process
