Active magnetic bearings for high-speed motors This post presents some basic information about active magnetic bearing technology in modern variable speed drive systems. Two principal solutions for electrically driven turbomachinery Electric drives for turbomachinery can be realized in two ways: Conventional drives with medium-speed motor and a speed-increasing gear High-speed Read more
High-speed drives:Introduction Since a long time we wanted to write more about high-speed drives, their theory, design, application etc. Finally we manage to publish this short post providing an introduction into high-speed drives. In line with our blog, the focus will be on medium voltage and medium/high-power drives. Introduction Variable Read more
To Gear or not to Gear? “To Gear or not to Gear: That is the question!” Dear readers, it is April 1, the Fool Day. However, we are not going to fool you. Instead, we have just allowed ourselves to paraphrase the famous quote by Shakespeare from Hamlet, Act 3 Read more
What efficiency can you expect from your drive system? In general, the efficiency of a drive system utilizing VFD is high. The differences come from the VFD topology, dimensioning and technical solution. As discussed in our previous post, the user shall always compare total efficiency of a complete drive system. Read more
