Spetec - Model SM04 -Stepper Motor Controller

The optionally available Spetec stepper motor controller SM04 is an in-house development that can be fixed directly to the pump. It has been designed for the operation of 2-phase stepper motors with step angles of 1.8° and 0.9°. Using the Spetec SM04, a single full step can be subdivided into 64 microsteps. This corresponds to 12,800 steps per revolution. This ensures that the equipment runs extremely smoothly and silently.
