Asynchronous vs Synchronous motor drives
Two basic AC motor types serve the industries today: asynchronous and synchronous motors. Which one fits better for variable speed drive applications? As you probably guess, the answer is not black and white. In this webinar you will learn how the selection of motor type impacts some aspects of a drive system, such as:
- Capability of drive system
- System dimensioning
- Motor control
- Efficiency and losses
- Performance
- Investment cost

LCI vs VSI
If you work with medium voltage variable frequency drives then those two abbreviations are certainly well-known to you: Load-Commutated Inverter (LCI) and Voltage Source Inverter (VSI). How do they compare? What do they have in common and where are the major differences?
In this webinar we cover various aspects such as history of both platforms, references, type of semiconductor, performance, output waveforms, control philosophy, power rating, scalability, compatibility with motors and more.
LCI vs VSI webinar is over. If you want to attend this webinar, contact us and schedule an individual date for replay.
