Induction motors are the workhorses of manufacturing, powering crushers, pumps, extruders, conveyor systems, and fans. When a motor trips on thermal overload during full-scale production, the entire manufacturing line grinds to a halt. In severe cases, prolonged overloading burns through the stator insulation, requiring an emergency rewind or motor replacement that results in tens of hours of unplanned downtime and hundreds of thousands of rupees in lost production.
Conventional bi-metallic thermal overload relays only react after winding heat has reached critical limits, abruptly tripping the contactor without prior warning to operators. They cannot warn operators that a mechanical jam, conveyor overload, or bearing drag is gradually pushing motor current from 80% to 110% of Full Load Amps (FLA).
Catching motor overloads before tripping occurs requires continuous high-speed analog sampling of current and thermal capacity registers, real-time comparison against motor service factors, multi-stage warning thresholds, and immediate mobile dispatch to electrical maintenance teams.
Our platform integrates directly with smart motor protection relays (Siemens Simocode, Schneider TeSys T, Rockwell E300) and VFDs over Profinet, Modbus TCP, and Ethernet/IP. It continuously monitors 3-phase current (RMS), thermal capacity used (%), stator winding RTD temperatures, and ground fault currents. By implementing a two-stage alert system (Warning at 90% FLA, Alarm at 105% FLA), operators can clear mechanical jams or reduce feed rates before the protective relay trips.

Transforms reactive motor protection into proactive mechanical and electrical maintenance, preventing costly production halts and extending motor operational life.
Built for high-speed industrial environments where downtime is measured in seconds.
Configures early warning alerts when motor current exceeds 90% FLA for longer than 30 seconds, allowing operators to throttle material feed before the protective relay trips at 105% FLA.
Monitors the electronic thermal model in smart relays (% thermal capacity used). Alerts engineers when heat accumulation indicates insufficient motor cooling or excessive start-stop cycling.
Detects phase current imbalances exceeding 5%, alerting maintenance before unbalance causes localized stator hot spots and premature insulation breakdown.
Detects instantaneous current spikes reaching 500% to 600% FLA upon starting or during operation, instantly notifying operators of mechanical seizure.
Records and visualizes inrush current curves and acceleration times for every motor start, alerting teams when starting times lengthen due to mechanical resistance.
Direct compatibility with leading global industrial automation and ERP ecosystems.
How data seamlessly flows from top-floor enterprise orders to shop-floor machine feedback.
The system continuously polls smart motor relays, drives, and PLC analog input cards, sampling instantaneous phase currents (Ia, Ib, Ic), line voltages, and winding temperatures.
Telemetry is normalized against motor nameplate Full Load Amps (FLA) and service factor ratings stored in the central asset asset database.
If motor load exceeds Stage 1 threshold (90% FLA) for a sustained duration, the system logs an operational warning and alerts the line operator console.
Upon reaching Stage 2 threshold (105% FLA) or rapid thermal capacity exhaustion, urgent alerts are dispatched via SMS and WhatsApp to the electrical maintenance technician on duty.
Trips and overload events automatically trigger maintenance notifications in SAP PM or the facility CMMS, complete with pre-trip current graphs and thermal traces.
