Is an asynchronous motor too big and not efficient enough for you? Or are you looking for an inexpensive and rugged alternative to the synchronous servo motor? Based on the "Bridge the Gap" principle, STOBER has brought a new motor class to market. The consistently encoderless Lean motors are strong and rugged like asynchronous drives and precise and compact like synchronous servo motors. For example, the motors can be used for automation tasks in harsh production environments.
