When the motor experiences overloading (current), underloading (current), phase failure, stalling, short circuit, leakage, unbalanced three phases, overheating, overvoltage, undervoltage, grounding, power, energy consumption analysis, winding insulation degradation, bearing wear, rotor eccentricity, winding aging, and voltage fluctuations, it triggers an alarm. The subsequent control action provides protection, and it comes with a 4-20mA output, RS485 network communication, analysis of motor lifespan, ensuring safe production, cost savings, and efficient production output.
