The course has been significantly updated in June 2025. The motor drive course has been divided into a basic part, one for troubleshooting, and one for grid connection requirements. The courses have been expanded to be more in-depth, with an emphasis on clear explanations and animations.
The motor drive and the conditions surrounding it are described to achieve an understanding of the necessary electrical technical conditions for correct operation and to avoid emitting unwanted noise. The basic structure is examined, providing a background for troubleshooting the installation, for example. This includes looking at single-phase and three-phase motor drives, as well as two-pulse and six-pulse couplings.
PWM (Pulse Width Modulation) and leakage current issues from frequency converters, including motor cables, are briefly highlighted.
Biggest source of errors in Industrial Installation
Noise, imbalance and DC on the grid
Rohde Consulting's experience from troubleshooting industrial plants is that frequency converters are the most frequent source of errors. It could be a faulty inverter, too high grid impedance (too low Ik,min) or incorrect installation technique. Typically, the current draw to the motor controller is looked at using different load levels. Take the motor drive course and the harmonic currents course is also recommended.
