Eurocircuits TV visited idastroem @ew2020
Our customer idastroem has developed an evaluation kit with which the sensorless control of BLDC motors can be tested without lengthy calibration and measurement runs. Eurocircuits was not only allowed to manufacture the printed circuit boards for the motor output stage and the adapter board, but also populated them, which impressed the embedded developer Markus Kräutner in terms of quality and adherence to delivery dates.
The idastroem controller monitors the motor's reaction to the control signals and uses a mathematical model to calculate the current rotor position and rotational speed. The calculation is based on a computer module from DH Electronics.
DH Electronics and idastroem demonstrate the solution in practice on a wheel of fortune.
