Our more compact version for the encoderless Lean motor. The compact stand-alone SC6 drive controller allows for sensorless control of STOBER LM series Lean motors. These motors provide energy efficiency at the performance level of a synchronous servo motor. They also guarantee high investment protection, thanks to energy efficiency class IE5 and the corresponding higher efficiency compared to IE4 asynchronous motors. However, the SC6 can also be used in combination with asynchronous motors or synchronous servo motors with encoders (e.g. the STOBER EZ series). The SC6 drive controller is available in three sizes up to 19 A: sizes 0 and 1 as a double-axis controller, size 2 as a single-axis controller. Various safety options are also available.
