Purpose and goal

The goal of the project was to demonstrate the feasibility of the “Smart current sensor” circuit board concept. The general purpose was to measure the current in an electric drive at a high-frequency rate, enabling innovative self-diagnostic techniques. Moreover, the board should be capable to process the high-frequency rate data measurements and communicating it to the network of electric drives. The project result is a joint of custom-made and custom-made and market-available hardware, which satisfies all the project purposes.

Expected results and effects

The successful results of the performed feasibility study allow the project’s parts to continue implementing the “Smart current sensor” circuit board concept in an experimental setup. This consists of an electric motor supplied by a frequency converter that contains self-diagnostic techniques enables by the obtained project results. Subsequently, the electric drive can be connected to a network allowing the exchange and the possible further processing of the high-frequency measured data.

Planned approach and implementation

The project was fruitfully run thanks to the expertise coming from all project’s parts. With this approach it was possible to determine the best solution for all the hardware components of the “Smart current sensor” circuit board concept and to properly design the custom-made parts. Additionally, the project risks were mitigated with the help of the industrial expertise of ABB.
