LTN Slip Rings

LTN Slip Rings supplier

Operating principle of a slip ring

Slip rings are electromechanical components which allow electrical power or signals to be transmitted between stationary and rotating systems, or between two counter-rotating components, via a sliding contact (brush). Aside from core requirements like wear resistance and contact quality, slip ring systems vary depending on the actual conditions of use and the specified transmission power. Our slip ring systems withstand harsh environmental influences such as corrosive, salty air or severe vibration. They thus ensure the reliable functionality of entire machine systems. In addition, we offer contactless fibre-optic rotary joints for contactless transmission at high data rates. Slip ring systems are found in many electrical machines. The spectrum ranges from just a few mV or mA to 200 A and 1500 V.

Typical applications:

Surveillance systems (e.g. radar), Medical technology (e.g. support arm lamps), Renewable energy (e.g. wind turbines), Radio frequency technology, Digital data transmission, IT networks

LTN Resolver

LTN Resolver supplier

Operating principle of a resolver

After optical rotary encoders, resolvers are the most commonly used type of displacement and angle sensor. They convert the angular position of a rotor to two voltages. The absolute position can be represented clearly in this way. Modern resolvers are usually brushless and the information is transmitted through induction. Unlike rotary or incremental encoders, resolvers provide an absolute signal within a single revolution and therefore do not have to be calibrated after switching on.

Resolvers are used for open and closed-loop control tasks such as electric servo drives, positioning drives and machines with interdependent motors. The robustness and availability of the systems are of central importance. Our brushless resolvers operate without wear and are fail-safe – even in the harshest environmental conditions (e.g. extreme temperatures).

LTN Rotatry Encoders

LTN Encoders supplier

Operating principle of a rotary encoder

For many years, LTN Servotechnik has been developing and manufacturing customised rotary encoder solutions for extreme environments to enable precise measurement of movements and positions. Rotary encoders (or angular position encoders) are optical, magnetic or mechanical sensors which form signals from movements. They detect the current position of a shaft and convert even fractions of an angle degree to an electrical signal.

The digital output signals of a rotary encoder are the starting point for modern, high-precision position control systems. Thus, a drive unit can perform reproducible movements and return to the home or reference position after a work process.
