DYMOTRON Product Lines We Repair
Our engineers are trained on the full DYMOTRON product range. Below are the major product families we service.
DYMOTRON DC Drive Series
Thyristor-controlled and transformer-based DC power supplies for legacy and modern DC motor applications. Common faults include thyristor firing circuit failures, control board component degradation, and thermal management issues in high-duty-cycle environments.
DYMOTRON AC Vector Control Drives
Advanced frequency converters and vector drives for three-phase induction motors with integrated PLC and diagnostic interfaces. Typical repair scenarios involve IGBT module failure, encoder signal losses, and firmware communication breakdowns.
DYMOTRON Servo Drive Systems
High-precision servo amplifiers for synchronous and brushless motor control in positioning and automation applications. Common failures include current sensor faults, resolver/encoder interface degradation, and closed-loop stability issues under sudden load transients.
DYMOTRON Control Interface Modules
Programmable logic controllers and human-machine interfaces for industrial motor and drive coordination. Repair demands center on analog input/output circuit failures, communication port degradation, and firmware recovery after supply surge events.
DYMOTRON Power Factor Correction Units
Static capacitor banks and active harmonic filters designed to improve power quality in motor-driven plants. Frequent issues include capacitor element breakdown, thyristor gate-drive circuit failures, and reactive power regulation circuit malfunctions.
DYMOTRON Regenerative Braking Modules
Bidirectional energy recovery systems for overhauling loads and crane duty cycles. Typical repairs address freewheeling diode failures, dynamic braking resistor circuit faults, and voltage regulation instability during rapid deceleration.

Common DYMOTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYMOTRON equipment arriving at our workshop.
- ✓IGBT module thermal runaway and junction failure — DYMOTRON AC vector drives expose IGBT modules to thermal stress under continuous overload or in poorly ventilated control cabinets. Moisture ingress and inadequate thermal paste reapplication during field maintenance accelerates junction degradation and gate-oxide wear.
- ✓Thyristor commutation circuit instability and misfiring — DYMOTRON DC drive thyristor circuits require precise gate pulse timing and synchronized commutation sequencing. Component drift in timing capacitors, isolation transformer core saturation, and snubber circuit degradation cause phase-angle distortion and erratic motor acceleration.
- ✓Encoder signal loss and resolver interface noise corruption — DYMOTRON servo drives rely on high-resolution feedback from incremental encoders or sine-cosine resolvers. Industrial EMI, cable shield deterioration, connector pin corrosion, and resolver winding insulation breakdown introduce noise that closes servo feedback loops and triggers fault codes.
- ✓Control board analog-to-digital converter offset drift and quantization errors — DYMOTRON control interface modules employ precision 12-16 bit ADCs for current sensing, voltage feedback, and process variable monitoring. Thermal aging, reference voltage drift, and printed circuit board trace capacitive coupling introduce systematic measurement errors that degrade control loop accuracy and trigger false alarm conditions.
- ✓Firmware corruption and communication protocol timeouts — DYMOTRON drives and controllers store operating firmware in on-board flash memory and EEPROM. Power supply interruptions during programming, lightning surge transients, and watchdog timer resets corrupt firmware images and cause repeating boot loops, serial port timeouts, and loss of parameter persistence.
- ✓Power capacitor element degradation and reactive power instability — DYMOTRON power factor correction and harmonic filter units contain large electrolytic or film capacitor banks exposed to continuous line voltage stress and harmonic current distortion. Aluminum electrolytic capacitors age under ripple current heating; film capacitors develop micro-cracks under dielectric stress, leading to progressive capacitance loss and ESR increase.

We offer PAN India door-to-door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major manufacturing hubs. All repairs are processed at our Vadodara, Gujarat facility with turnaround times of 5-7 business days for component-level work.
What is the typical repair turnaround time for DYMOTRON AC vector drives?+
DYMOTRON AC vector drives typically require 5-7 business days for full diagnostic, component replacement, and load testing. Emergency 48-hour repair options are available for critical production downtime situations. Our engineers perform in-circuit IGBT module testing, gate-drive signal verification, and encoder interface noise analysis before closure. We provide detailed technical reports documenting all faults and corrective actions.
Can Synchronics repair DYMOTRON servo drive resolver interface failures?+
Yes, Synchronics has specialized expertise in DYMOTRON servo drive resolver circuits. We test sine-cosine resolver output signals with precision phase analyzers, replace resolver output conditioning boards, recalibrate feedback gain and offset trimmers, and validate closed-loop stability across full motor speed range. Incremental encoder preamplifier circuits are also serviced with noise filtering optimization and signal integrity restoration.
Do you stock genuine DYMOTRON replacement parts and components?+
Synchronics maintains a curated inventory of DYMOTRON power semiconductors, capacitor banks, gate-drive modules, and control board components. For spare parts not in stock, we leverage our 30-year vendor relationships to source genuine DYMOTRON components within 2-3 business days. We can also specify equivalent industrial-grade components from Siemens, ABB, and Danfoss where direct DYMOTRON parts are obsolete, with full cross-reference documentation.
How do you diagnose DYMOTRON firmware corruption and communication faults?+
Synchronics uses industry-standard programming equipment and DYMOTRON software tools to extract flash memory contents, identify corrupted sectors, and perform in-circuit reprogramming. We test serial, Ethernet, and Profibus communication interfaces with precision protocol analyzers. Parameter configuration is recovered from backup files or reset to factory defaults with documentation. All firmware updates are logged and verified with functional testing under simulated load conditions.
How do I send my DYMOTRON 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 DYMOTRON 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 DYMOTRON 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 DYMOTRON 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.
