Torsional vibration

The measurement and analysis of torsional vibrations is of paramount importance in the development of powertrains of all kinds (ICE, hybrid, EV, hydrogen). Our complete solution for torsional vibration analysis in the automotive, motorsport and heavy-duty sectors includes speed sensors, data acquisition and evaluation as well as engineering services. Typical applications include the analysis of clutches, belt systems, chain drives, transmissions and dynamic investigations of drivetrains.

Valve dynamics

The investigation of valve systems with the Rotec measurement and analysis solution has been a proven means of optimizing valve trains for many years. In addition to conventional measurement on cylinder heads that have been dragged, measurement on fired engines in particular offers in-depth analysis options using MR sensor technology and helps with optimization, especially in applications with the highest demands on performance and emissions.

Transmission error (TE)

Analyzing the transmission error of transmissions in a wide range of applications such as classic car and truck transmissions, electric axle drives, reduction and transfer gearboxes as well as planetary gearboxes in the wind energy sector has been a focus of Rotec's measurement technology solution for many years. The high-precision recording of angular positions and the precise analysis of the data through to automated reporting form the basis for investigations in the R&D area as well as for the end-of-line inspection of gear pairs and complete gearboxes.

Continuous monitoring

In addition to classic R&D applications, angle-based speed measurement and evaluation in the order and time range also form the basis for continuous monitoring of components, drive trains and turbines. Rotec monitoring solutions are used for continuous monitoring of steam turbines, as well as for increasing the efficiency of diesel generators in the marine and heavy-duty sectors and for stationary generators. Early detection of critical system conditions enables efficiency increases, reduces operating risks and also forms the basis for predictive maintenance.

Modular measuring system

With its own speed sensors, signal conditioning, modular RASdelta front end (DAQ), measurement and analysis software and engineering services, ROTEC offers a complete solution for analyzing rotating components.

Market-leading measuring principle

The ROTEC measuring method is based on the acquisition of angle-equidistant speed signals using a high-precision 12.3GHz counter card. Additional analog, CAN, strain gauge and temperature inputs allow the analysis of complex systems.

Comprehensive analyses

The ROTEC analysis software enables comprehensive analyses of rotating components and offers specialized modules for the analysis of valve systems and gearboxes (transmission error / TE and single flank rolling test).

Expert know-how

ROTEC products and services are the result of expert knowledge and over 35 years of experience in measurement technology. Our developers and our support team know the requirements from practical experience and are happy to help with new measurement tasks.

Competent solutions

Individual measurement technology solutions and the handling of complete and partial projects by ROTEC ENGINEERING enable high flexibility with short lead times. This includes CAD design, sensor application, mechanical processing and the execution of measurements including reports.

Global presence

A global sales and support network supports ROTEC customers in all relevant markets. Customer training and ROTEC ENGINEERING services can be implemented globally.

What does the ROTEC solution for rotation analysis look like and what does RAS mean?

The ROTEC Rotational Analysis System (RAS) has been used for more than 30 years by users in the mechanical engineering, automotive, power generation and motorsport industries for the comprehensive analysis of rotating components.

With its unique measurement method using a 12.3 GHz counter card and a strictly angle-based approach to rotational speed detection and analysis, the RAS system offers users an unparalleled advantage.

ROTEC offers not only optical and magnetic speed sensors including signal conditioning adapters, but also the modular measuring system RASdelta as well as specialized and user-friendly software for measurement and analysis. This enables a complete solution from a single source. The ROTEC measurement technology products are perfectly matched to each other and deliver meaningful results within a very short time after the uncomplicated setup of the measurement chain.

Thanks to the angle-based approach to speed measurement, problems such as sensor vibrations can be detected after the first measurement and rectified immediately. This effectively prevents costly incorrect measurements.

Our team of experts at ROTEC ENGINEERING, consisting of long-standing users, will be happy to assist you with challenging tasks.

Are there options for customizing the measurement systems and software?

The ROTEC RASdelta front end is a versatile modular measurement system that can be individually configured with 8 or 16 measurement cards to meet your specific measurement requirements.

Our RAS software offers you a comprehensive modular system for analyzing rotating components and complex systems. It is an effective tool for machine builders and requires no programming knowledge to carry out measurements or perform evaluations.

If you have specific metrological questions, our experienced ROTEC ENGINEERING consulting team will be happy to support you.

Does ROTEC offer other services in addition to the measuring systems, e.g. individual consulting or project support?

ROTEC offers not only speed sensors, signal conditioning, measurement systems (DAQ) and measurement and evaluation software, but also engineering and consulting services.

Our services include the design of measuring points in CAD, the mechanical processing of components, the application and calibration of sensors, the execution of measurement tasks and the evaluation of measurements in accordance with our customers' requirements, including the presentation of the results. The ROTEC ENGINEERING team can also implement sub-projects as part of project support.

Is there training or technical support for commissioning and integrating the measuring systems?

In addition to our annual ROTEC Training Week, which is held in both German and English, we also offer customized training courses for users. These training courses are specially tailored to your individual application of the ROTEC measuring system and include not only the theoretical basics and a detailed presentation of the software, but also practical demo measurements in your environment. This ensures that future users are optimally prepared for your specific application.

Furthermore, we are happy to support you in the commissioning of new measuring systems to enable you to become familiar with the settings and possibilities of the RAS software as quickly as possible.

How is support ensured and are there self-help options?

In addition to our sales and support team in Munich, which serves the Central European market directly from here, ROTEC also cooperates with local partners in many global markets. These partners support local users with trained personnel for all matters relating to ROTEC measurement technology, first-level support and sales inquiries.

Our customers around the world appreciate the proximity of our sales and support teams, as this enables us to guarantee effective support even for short-term questions.

In addition to personal contact, ROTEC also offers an extensive knowledge database for self-help. Please register for our knowledge database to obtain detailed information on measuring and evaluating torsional vibrations, transmission errors and valve systems, among other things.
