High-speed drives: VFD perspective In the introduction to high-speed drives [1] we have briefly described the design variants of semi high-speed and high-speed motors. The impact on construction of the motor is significant. High-speed motors can be quite different compared to the conventional machines. But how about the VFD? What 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
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
