Servo motors - Import export

Servo motors in hydropower plants normally operate water hydraulically. These servo motors perform the functions of opening, closing and control of shutoff and regulating devices and must be able to maintain the setting position at any prevailing pressure.

2-phase stepper motors Our 2-phase stepper motors are reliable and low-cost drives with a long service life. They are available in different sizes and types of power output, are continuously developed and are thus suitable for a variety of applications. AC servo motors The AC servo motors meet the highest demands regarding dynamics and accuracy and are used if dynamic, exact positioning or smooth running characteristics are required. The different types of power output and sizes cover the most diverse requirements. The benefits at a glance Highly dynamic High efficiency Long service life

The spring-applied single-disc brakes in the Servo Line series are designed to operate dry. They can be mounted to the A-face or B-face end shield inside the servo motor. The braking action generated by the compression springs is neutralized by applying the electromagnetic principle involving generation of a magnetic field. The brakes engage in unpowered condition and release when DC voltage is applied. The brakes are equipped with a flange and firmly fastened with screws. Thanks to a specially developed and patented manufacturing method, the rated air gap tolerance can be reduced to a few hundredths of a millimetre, providing enhanced power. Moreover, the brakes have a toothed hub/friction disc connection with minimal circumferential backlash. Standard version is suitable for flange mounting and face mounting.

The PM Line includes permanent magnet brakes in which the braking force is generated by a permanent magnetic field. The brake thus works in a de-energized condition and fulfill the following functions: Holding, positioning and emergency stop. The neutralization of the braking force is effected by the counteracting electric field, granting a high degree of security, even in the case of power failure. Permanent magnet brakes are characterized by a secure, residual-moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Therefore, they are ideal for servo motor applications.

This series comprises valves with two connections that are operated by an electric motor. They are characterized by the fact that the valve stroke can be adjusted steplessly and held in place by a motor using a setpoint signal (420 mA or 010 V). This makes this series particularly suitable for precise dosing applications, as the servo motor reliably processes setpoint deviations of 1%.
