Massive changes in the field of Electrical Drive Systems

Bitflux - Advanced drive control without position sensorThe increasing meaning of energy costs as well as greenhouse gas emissions and the accompanying implementation of comlulsory efficiency standards lead to a perspectively conversion from inefficiently run asynchronous machines to inverter-fed synchronous machines. To achieve an efficient control of synchronous machines, however, this change requires the use of a positon sensor to determine the rotor position.

Advantages

The elimination of the positon sensor used for control of synchronous machines would indeedoffer advantages for almoust all applications, either concerning the reduction of cost and space, the lower failure probability, or an increase of robustness. Especially, it would be useful to dispense with this expensive and vulnerable mechanical sensor technology in case of cost sensitive and security-critical applications.

Problems of sensorless control schemes

However, common sensorless control schemes lead to high development costs and risks due to their technological requirements, and show some disadvantages compared with control schemes using a position sensor. Examples include the necessary reduction of dynamic, the emission of noise at standstill, parameter dependencey, problems affecting the transition between low and high speed and the lack of suitability for machines with concentrated winding.

We have the solution

We render drives more cost effective, compact, robust, reliable.

In the course of our research we have succeeded in realising applications with enhanced demands for efficiency and performance without positon sensor and in reducing system costs as well as the failure probability as a result.

Hence, Bitflux today enables sensorless applications, which so far could only be realised using a position sensor. Our software bundle dynAIMx® can be installed as add-on library to the existing controller and normally causes no additional hardware costs.

The Bitflux company has its roots in a team of scientists of the Technical University of Munich. The Federal Ministry For Economics and Energy has been funding the research project on sensorless control of synchronous machines within the scope of the EXIST funding programme from mid-2015 until mid-2018. The founding of Bitflux GmbH took place at the beginning of 2016 as a spin-off of the Technical University of Munich.

 

The Bitflux expertise is based on 20 man-years of research and development in the field of sensorless control, in which significant improvements were achieved throughout further in-house development beyond the validation of all methods known in literature.
