DREHMO Equipment We Repair — By Category
DREHMO Product Lines We Repair
Our engineers are trained on the full DREHMO product range. Below are the major product families we service.
DREHMO Electromagnetic Clutches
AC and DC electromagnetic clutches for instant torque engagement and disengagement. Common faults include solenoid coil burnout, air gap misalignment, and friction surface wear. Synchronics rebuilds clutch assemblies with precision air gap calibration.
DREHMO Torque Limiters (Spring Type)
Spring-loaded torque limiters protecting machinery from overload conditions. Failures stem from spring relaxation, friction ring degradation, and calibration drift. Our technicians reset spring preload and replace wear components to factory specifications.
DREHMO Friction Couplers
Slip-ring friction couplers for shock absorption and vibration damping in conveyor and pump drives. Issues include friction lining separation, bore corrosion, and hub slippage. Synchronics relines friction rings and restores bore geometry.
DREHMO Modular Coupling Systems
Flexible multi-element couplings for textile spindle drives and paper mill rollers. Common wear: elastomer element cracking, bolt thread damage, and runout issues. Full element replacement and shaft alignment performed in-house.
DREHMO Slip-Ring Assemblies
Carbon brush and slip-ring subassemblies for rotating contactors in sugar centrifugals and spinning frames. Faults: brush arcing, ring oxidation, and intermittent contact. Synchronics reconditions rings and fits premium brushes.
DREHMO Safety Torque Limiters
Precision safety-rated torque limiters (SIL 2/3 compatible) for press and injection molding equipment. Issues include calibration drift, micro-slip wear, and release mechanism stiction. Synchronics recalibrates and validates load cells.

Common DREHMO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DREHMO equipment arriving at our workshop.
- ✓Electromagnetic clutch solenoid coil burnout — Extended duty cycle without adequate thermal dissipation, or sustained low-voltage condition damaging insulation. DREHMO clutches rated for 40% duty cycle often fail when run continuously in Indian textile mills during high-season production.
- ✓Torque limiter spring preload relaxation and slippage — Fatigue stress cycling and loss of spring tension over 5-8 years of operation. Sugar mills and cement plants experience this after extended monsoon storage or temperature fluctuations in uncontrolled warehouses.
- ✓Friction ring surface glazing and low torque transmission — Friction material breakdown due to insufficient lubrication, contamination by mill dust, or repeated thermal cycling. DREHMO couplers operating in unenclosed textile spinning frames are highly susceptible.
- ✓Slip-ring brush arcing and intermittent electrical contact — Carbon brush wear, ring oxidation or eccentricity, and spring pressure loss. Common in sugar centrifugal discharge clutches exposed to vibration and moisture-rich environments.
- ✓Coupling hub bore stress cracking and radial play — Over-torque transients, misalignment stress, or improper installation causing hoop stress concentration. Beverage bottling lines and conveyor systems under intermittent shock loads fail prematurely.
- ✓Safety torque limiter load cell drift and false release — Strain gauge signal degradation due to mechanical hysteresis, creep, or corrosion on load cell sensing elements. Affects press safety circuits in automotive parts suppliers across Gujarat and Maharashtra.

Frequently Asked Questions — DREHMO Repairs
Do you repair DREHMO equipment anywhere in India?+
Yes, Synchronics repairs the full DREHMO product range — electromagnetic clutches, torque limiters, friction couplers, slip-ring assemblies, and safety limiters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and 50+ other cities. All repairs completed at our Vadodara, Gujarat facility with guaranteed 48-hour turnaround for standard clutches.
What is the typical repair cost for a DREHMO electromagnetic clutch?+
DREHMO electromagnetic clutch repair costs INR 8,000 to 25,000 depending on model size and coil damage extent. Solenoid rewinding costs INR 5,000–12,000. Synchronics provides free diagnostic and written quote within 4 hours of receipt. Many repairs are 40% cheaper than replacement, especially for EK-100 and EK-160 units common in Indian textile mills.
Can Synchronics recalibrate DREHMO safety torque limiters to SIL 2 standards?+
Yes. Synchronics recalibrates DREHMO STL series limiters using traceable deadweight test rigs and certified calibration blocks. We validate release accuracy to ±3% of setpoint and issue SIL 2 compliance certificates recognized by Indian automotive and press safety auditors. Typical recalibration turnaround is 5 working days.
Do you stock genuine DREHMO spare parts and friction linings?+
Yes. Synchronics maintains stock of genuine DREHMO friction rings, spring assemblies, carbon brushes, and solenoid coils for EK, TL, FC, and STL series. We also supply OEM-equivalent friction material bonded to DREHMO original specifications. Custom friction linings cut to bore size are available within 3 days.
How do I know if my DREHMO torque limiter needs recalibration?+
Warning signs include intermittent slippage at rated torque, inability to achieve full engagement, or inconsistent release torque across repeated cycles. Sugar mills and textile plants should recalibrate DREHMO limiters every 3-4 years or after major shock events. Synchronics field audits are available for on-site diagnosis — contact our Vadodara office to arrange.
How do I send my DREHMO 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 DREHMO 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 DREHMO 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 DREHMO 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.
