Stellar series

The Stellar series is especially designed for high speed rotating motor applications.

The Stellar series consist of the S3-400/70, S3-400/100 and the S3-400/120 drives for high speed motor applications. They are designed according to automotive standards, resulting in a cost optimized, compact and liquid cooled drive for motor speeds exceeding 100.000rpm. Moreover, the drive allows for sensorless control and highly dynamic loads. The drive-motor combination is typically used for compressor applications such as hydrogen fuel cells, stationary power generation and range extenders.
