TMEIC Equipment We Repair — By Category
TMEIC Product Lines We Repair
Our engineers are trained on the full TMEIC product range. Below are the major product families we service.
TMEIC Medium-Voltage Drives (3.3kV-11kV)
Load commutated inverter (LCI) and synchronous reluctance drives for kiln drives, ball mills, and compressors. Common faults include thyristor gate unit failures, control circuit board degradation, and line-side converter issues causing phase loss or commutation failures.
TMEIC Cycloconverters
Fixed-frequency and variable-frequency cycloconverters for variable-speed mill drives and large synchronous motor applications. Prone to thyristor stack failures, gate signal isolation breakdown, and output transformer core saturation causing temperature rise and efficiency loss.
TMEIC Control & Gate Driver Units
Advanced gate drive modules, firing control boards, and power circuit boards for TMEIC drive systems. Typical failures include optocoupler deterioration, power supply ripple generation, and control signal timing drift under thermal stress.
TMEIC Input Line Reactors & Filters
12-pulse and 24-pulse line-side reactor assemblies that protect medium-voltage grids from harmonic distortion. Failure modes include core winding insulation breakdown, thermal hotspots, and oil degradation in enclosed reactor units.
TMEIC Synchronous Reluctance Motor Controllers
Specialized drives for high-torque, low-speed synchronous reluctance motors in mining and cement industries. Common issues include magnetic flux linkage estimation errors, rotor position sensor failures, and current loop instability causing speed oscillations.
TMEIC Power Modules & Capacitor Banks
DC link capacitor assemblies, snubber networks, and power semiconductor mounting systems for TMEIC inverter bridges. Failure mechanisms include capacitor dry-out, solder joint cracking under vibration, and semiconductor thermal cycling fatigue.

Common TMEIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TMEIC equipment arriving at our workshop.
- ✓Thyristor gate unit open-circuit failure — TMEIC medium-voltage drives employ phase-shifted thyristor bridges controlled by gate drivers that degrade under sustained thermal cycling. Gate driver optocouplers and power supply capacitors in the GDU-5000 and CCV control boards frequently fail after 8-12 years of continuous operation, especially in high-ambient-temperature Indian mill environments.
- ✓Line reactor core saturation and temperature rise — TMEIC 12-pulse and 24-pulse line reactors (LR-12P-6.6kV, LR-24P-11kV) experience core saturation when grid impedance drops or harmonic injection increases from nearby frequency converters. Oil insulation deteriorates, winding hotspots develop, and core laminations may separate.
- ✓Synchronous reluctance motor rotor position sensor failure — TMEIC SRM controllers rely on incremental encoders or resolver feedback to track rotor angle and maintain flux linkage. Sensors fail due to bearing wear, connector corrosion from cement dust or mining moisture, or resolver winding insulation breakdown after 6-8 years of unfiltered industrial operation.
- ✓DC link capacitor bank dry-out and ripple voltage rise — TMEIC power modules use electrolytic capacitor banks (DCL-Cap-Bank-MV series) that lose capacitance as internal electrolyte evaporates under sustained 50-60 deg C ambient heat and high ripple current stress common in Indian steel mills and power plants. ESR increases, causing voltage ripple to spike above 15% design margin.
- ✓Control circuit board solder joint fatigue cracking — TMEIC GDU and PDU circuit boards experience mechanical vibration from attached heatsinks, motor frame coupling, or transport shock that induces thermal cycling fatigue in PCB solder joints. Micro-cracks develop at component leads and via connections, causing intermittent signal loss and erratic gate firing patterns.
- ✓Cycloconverter commutation failure and output voltage collapse — TMEIC CCV-Series cycloconverters depend on precise thyristor commutation timing synchronized to the input line voltage. Grid voltage sags, phase unbalance exceeding 5%, or reactive power surge from nearby induction motors cause commutation angle collapse, forcing simultaneous thyristor conduction and DC link short-circuit trips.

Frequently Asked Questions — TMEIC Repairs
Do you repair TMEIC equipment anywhere in India?+
Yes. Synchronics repairs the full TMEIC product range — medium-voltage drives, cycloconverters, gate driver units, line reactors, and synchronous reluctance controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other industrial cities. Single facility in Vadodara, Gujarat with factory-certified TMEIC repair expertise.
What is the typical turnaround time for TMEIC medium-voltage drive repair?+
Standard TMEIC drive repair (GDU replacement, control board rework, capacitor bank refurbishment) takes 10-14 working days from receipt to bench testing completion. Complex failures requiring thyristor stack replacement, cycloconverter coil rewinding, or power module redesign may require 18-25 days. We offer priority repair with 5-7 day turnaround for critical mill drive outages if parts availability permits.
How do I know if my TMEIC drive has a gate driver failure versus a thyristor stack problem?+
Synchronics performs non-destructive diagnostic testing without opening the drive enclosure. We capture gate pulse waveforms, measure thyristor leakage current, and monitor commutation voltage signatures under no-load conditions. Gate driver failures show absent or distorted gate signals; thyristor faults show voltage spikes or current loss. This 2-4 hour diagnostic typically costs Rs 2,500-4,000 and directs the most cost-effective repair path.
Do you stock spare parts for TMEIC drives, or must I source them separately?+
Synchronics maintains strategic inventory of high-failure TMEIC components — optocouplers, power supply modules, capacitor banks, and gate driver ICs — for most GDU-5000, PDU-Series, and CCV control boards. We also have relationships with authorized TMEIC distributors in India for long-lead items like thyristor modules or custom reactor coils. Lead times range from same-day (stock items) to 6-8 weeks (custom power assemblies).
Can Synchronics retrofit my older TMEIC LCI drive with modern firmware or Ethernet connectivity?+
Yes, within limits. Synchronics can upgrade GDU and PDU control boards with modern microcontroller firmware that preserves original thyristor commutation logic while adding real-time diagnostics and email alerting for fault conditions. However, retrofitting legacy 1990s TMEIC drives with Ethernet requires integration of new Modbus/TCP gateway modules that must be validated in your specific motor and grid environment. Contact us for a technical feasibility assessment.
How do I send my TMEIC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a TMEIC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on TMEIC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your TMEIC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
