RotorProtek® is a controller capable of calculating motor speed and torque by measuring only instantaneous rotor currents without the need for additional sensors, enabling the integration of advanced control and protection features. Motor starts are no longer dependent on load, electrolyte temperature or grid conditions. Start your motor according to a configured curve. Protect the slip ring chamber and gearbox using torque control and conditioning monitoring techniques. Analyze starts and decide how do you want to start your motor. All this information connected to your SCADA system and accessible from your smartphone without the need for cables or additional sotfware.
RotorProtek® offers an intuitive method of communications, allowing the user to set up, monitor or service the starter with just a smartphone, tablet or computer. No additional apps or sotiware is required; simply connect to the device with your preferred web browser to access all available features. Communication is possible without the need for internet access and at a distance of up to 20 meters with the starter panels closed.
