CPL Product Lines We Repair
Our engineers are trained on the full CPL product range. Below are the major product families we service.
Spring-Applied Brakes (Power-Off Brakes)
CPL spring-applied brakes are fail-safe electromagnetic brakes used on crane hoists, conveyor drives, and press machines. Common failures include coil burnout, weak spring return, armature chatter, and control relay stiction in high-temperature foundry and heat-treatment environments.
Power-On Brakes (Electromagnetic Holding Brakes)
Used in vertical lifting applications and load-holding in textile dyeing machines and printing presses. Repair issues include energised coil failure, armature seizure due to coolant contamination, and control circuit voltage drop affecting brake release.
Brake Control Electronics
CPL 24V and 230V AC control cards, DC solenoid drivers, and thermal overload units. Failures include capacitor degradation in humid mill environments, relay contact welding, and PWM circuit damage from transient surges on unshielded wiring.
Electromagnetic Clutches
CPL friction and eddy-current clutches used in winding drives, printing tension control, and gearbox soft-start applications. Common wear includes friction material glazing, coil insulation breakdown, and bearing deterioration under continuous duty.
Load Brake Kits for Sugar Industry
Specialized CPL brake assemblies for sugar mill roller presses and bagasse conveyor safety systems. Faults include cement dust ingress causing armature wear, spring fatigue after 5-7 years of continuous start-stop cycling, and coil overheating in poorly ventilated plant rooms.

Common CPL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CPL equipment arriving at our workshop.
- ✓Brake coil open-circuit or high resistance — CPL brake coils fail due to thermal cycling in hot mill environments, moisture ingress through damaged terminal blocks, and loose wire-to-coil connections in vibration-prone machinery. Resistance rises above 50% nominal, preventing full energisation and causing brake slip.
- ✓Armature chatter or intermittent engagement — CPL electromagnetic brakes develop armature chatter when control voltage is borderline (below 85% nominal), spring preload weakens, or air gap increases due to mechanical wear. Common in press machines with worn pivot pins and in conveyor brakes after 6+ years of service.
- ✓Brake will not release or sticks in engaged position — CPL power-on brakes stick when armature faces oxidise or seize due to corrosion, rust particles lodge in air gap, or coil insulation failure causes phase-to-frame short heating the brake. Spring-applied brakes stick if springs lose tension or armature bearing binds from coolant contamination.
- ✓Control relay failure or no brake response to command — CPL brake control cards fail when relay contacts weld or pit from inductive load switching without proper snubbing, capacitors dry out in hot plant environments, or transistor drivers fail from transient overvoltage on unshielded coil leads. Weak 24V supply or corroded terminal blocks also prevent relay activation.
- ✓Spring-applied brake loses holding force gradually — CPL spring-applied brakes weaken over 5-8 years as Belleville springs relax, friction material wears, and spring preload creeps. In sugar mills, cement and bagasse dust accelerate armature wear. Humidity causes rust on friction surfaces, increasing drag and reducing holding capacity.
- ✓Clutch slips or will not transmit full torque — CPL friction and eddy-current clutches slip when friction material glazes under continuous slip-speed operation, bearing preload loosens from vibration, or coil shorts develop reducing magnetic field strength. In winding and printing drives, oil splatter glazes friction surfaces in 3-4 months of duty.

Frequently Asked Questions — CPL Repairs
Do you repair CPL brakes and clutches across India?+
Yes. Synchronics maintains a 180-person engineering team at our Vadodara facility and offer same-day PAN India pickup from all major industrial cities — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. CPL brake assemblies, control electronics, and clutch units are repaired in-house with OEM-equivalent quality. Most CPL units return to service within 3-5 working days.
What is the typical turnaround time for CPL brake repair?+
Standard CPL brake repairs take 3-5 working days including diagnostics, parts procurement, rebuild, and test-run. Emergency rush repairs (coil replacement, armature resurfacing, control card replacement) are completed within 24 hours if parts are in stock. We stock common CPL coils, springs, friction material, and control relays at our Vadodara facility. Urgent repairs can be picked up same-day if reported before 2 PM IST.
Can you rewind and test CPL brake coils for Indian mill environments?+
Yes. Synchronics has in-house coil winding equipment and can rewind damaged CPL brake coils to exact factory specifications. We test all rewound coils for resistance, insulation breakdown, and thermal performance before fitting. For critical sugar, textile, and steel mill applications, we apply additional conformal coating and seal terminal blocks to withstand high humidity, dust, and temperature swings typical of Indian manufacturing plants.
How do I know if my CPL brake coil has failed?+
Signs of CPL brake coil failure include: (1) brake does not engage fully or slips under load, (2) coil gets unusually hot or smells of burnt insulation, (3) brake is slow to release, (4) multimeter reads high resistance (>20 ohms above nameplate) or infinite resistance (open circuit), and (5) control voltage at brake terminals is normal but brake does not respond. Contact Synchronics for free remote diagnostic advice — we can guide you through simple resistance tests to confirm failure.
What is your warranty on CPL brake and clutch repairs?+
All CPL repairs carry 12 months parts and labour warranty covering manufacturing defects, coil burnout, control circuit failure, and mechanical wear under normal operation. We do not warranty external damage, mechanical abuse, or undersized equipment (e.g. motor with insufficient torque for brake duty). Extended 24-month warranties are available on critical production equipment. All warranty claims are processed within 7 days.
How do I send my CPL 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 CPL 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 CPL 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 CPL 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.
