COILTEK Product Lines We Repair
Our engineers are trained on the full COILTEK product range. Below are the major product families we service.
COILTEK Solenoid Coils
Direct-acting and pilot-operated solenoid coils for pneumatic and hydraulic valves. Common issues include winding insulation breakdown, coil bobbin cracks, and open-circuit failures due to moisture ingress or thermal cycling in high-temperature industrial environments.
COILTEK Voice Coil Assemblies
Linear voice coil motors and electromagnetic actuators used in positioning systems, medical devices, and precision automation. Faults include coil detachment, magnet misalignment, and voice coil wire breakage from mechanical fatigue or electromagnetic stress.
COILTEK Inductor Assemblies
Power inductors, choke coils, and filter inductors for variable frequency drives, UPS systems, and harmonic mitigation. Repair focus includes burnt windings, saturation-induced heating, and core lamination separation caused by high-frequency switching stress.
COILTEK Custom Coil Windings
Application-specific wound coils for transformers, relays, and electromagnetic devices. Common failures stem from insulation degradation under thermal stress, coil turn-to-turn shorts, and mechanical damage during installation or transport in Indian manufacturing plants.
COILTEK Relay Coils
Electromagnetic coils for control relays, contactor coils, and latching relay systems used in motor control centers and switchgear. Faults include coil open circuits, burnt contacts, insulation charring, and mechanical armature stiction.

Common COILTEK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COILTEK equipment arriving at our workshop.
- ✓COILTEK solenoid coil open-circuit failure — Winding insulation breakdown due to sustained moisture ingress in humid Indian factory environments or thermal cycling from valve operation. Coil bobbin micro-cracks expose copper wire to oxidation and short circuits.
- ✓COILTEK voice coil wire fracture and voice coil detachment — Mechanical vibration fatigue from continuous positioning duty or electromagnetic coil misalignment causing uneven stress distribution. Wire fatigue cracks propagate under alternating current and thermal cycling.
- ✓COILTEK inductor saturation and coil overheating — Excessive DC bias current or harmonic loading on VFD filter inductors causes core saturation, dramatically increasing core loss and winding temperature. Common in Indian power-quality-challenged plants with high harmonic distortion.
- ✓COILTEK relay coil contact pitting and chatter — Switching transient spikes, inductive load kickback, or insufficient contact suppression cause arc erosion. Control relay coils designed for clean DC loads often fail prematurely in motor control applications with high inrush current.
- ✓COILTEK custom coil turn-to-turn short and insulation tracking — Partial discharge and corona discharge in high-voltage custom coil windings; arcing between adjacent turns due to insulation degradation from age, humidity, or manufacturing defects. Tracking follows moisture paths through coil structure.
- ✓COILTEK solenoid stiction and sluggish valve response — Coil magnetic field weakening from partial winding degradation, or mechanical stiction caused by armature pitting, corrosion, or foreign material lodged between armature and pole piece.

Frequently Asked Questions — COILTEK Repairs
Do you repair COILTEK equipment anywhere in India?+
Yes. Synchronics repairs the complete COILTEK product range — solenoid coils, voice coil motors, inductors, relay coils, and custom windings. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bengaluru, and all other cities. All repairs handled at our ISO-certified facility in Vadodara, Gujarat. Turnaround is typically 5-7 days.
Can you rewind burnt or open-circuit COILTEK solenoid coils?+
Absolutely. Synchronics specializes in rewinding burnt solenoid coils to original COILTEK specifications. We measure the original coil OD, bobbin pitch, wire gauge, and insulation system, then rewind using polyester or polyimide enamel wire matched to the operating voltage and frequency. Complete impregnation restores moisture resistance and dielectric strength — critical for humid Indian manufacturing plants.
What is a COILTEK voice coil motor and why do they fail?+
COILTEK voice coil motors are linear electromagnetic actuators widely used in precision positioning, medical automation, and semiconductor equipment in India. They fail due to wire fatigue from vibration, coil detachment from mechanical shock, and magnet misalignment. Synchronics inspects magnetic gap uniformity, tests wire integrity with continuity testing, and re-potencies coils with precision fixtures to restore performance.
How do you test COILTEK inductors before returning them?+
We perform DC resistance measurement, AC inductance sweep across 50-60 Hz, insulation resistance testing at 500 VDC, and temperature-rise testing under rated current. Custom inductors are loaded into test jigs simulating actual VFD or filter circuit conditions. Full test reports provided with every inductor repair.
What is the typical cost to repair a COILTEK solenoid coil versus replacement?+
COILTEK solenoid coil rewinding typically costs 30-50% of replacement price, depending on coil size and complexity. Synchronics provides a free diagnostic quote within 24 hours. For high-volume users, we offer preventive maintenance contracts with discounted rewinding rates — contact our sales team for custom industrial pricing.
How do I send my COILTEK 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 COILTEK 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 COILTEK 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 COILTEK 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.
