COLTER AND PETERSON Product Lines We Repair
Our engineers are trained on the full COLTER AND PETERSON product range. Below are the major product families we service.
Drum Controllers & Reversers
Mechanical drum contactors used for motor speed and direction control in heavy industrial applications. Common failures include worn brush contacts, shaft bearing seizure, and synchronization issues between multi-stage drums. Synchronics restores drum controller function through precision rewinding and contact resurfacing.
Motor Control Centres (MCC)
Integrated panel solutions for managing multiple motor circuits with overload protection, soft-start capability, and thermal management. Faults typically involve tripped contactors, damaged starter coils, and blown control transformers. Synchronics rebuilds MCCs to original specifications with upgraded components where applicable.
Industrial Relays & Contactors
Electromagnetic relays and AC/DC contactors for switching, interlocking, and control circuits in mills, crushers, and compressor applications. Typical issues include burned contact surfaces, stuck armatures, and coil insulation breakdown under high ambient temperatures. Synchronics has stock of replacement contacts and provides full relay rehabilitation.
Automation Control Panels
Modular panel systems integrating relays, timers, and limit switches for sequence control in conveyor systems, textile machinery, and process lines. Failures stem from corroded terminals, failed timer mechanisms, and loose internal wiring due to vibration. Synchronics re-engineers panels with modern terminal blocks and vibration-resistant harnesses.
Soft Starters & Reduced-Voltage Starters
Electromechanical devices for limiting inrush current during motor start-up, reducing mechanical stress on gearboxes and couplings. Common failures include sticking star-delta switch contacts, failed resistor banks, and timing relay drift. Synchronics calibrates and restores soft starter timing and contact integrity.
Field Wiring & Terminal Systems
Industrial-grade terminal blocks, cable lugs, and distribution systems designed for high-vibration and high-temperature environments. Degradation occurs through oxidation of aluminum busses, loosening of screw connections, and insulation cracking. Synchronics cleans, re-crimps, and pressure-tests all connections to mil-spec standards.

Common COLTER AND PETERSON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COLTER AND PETERSON equipment arriving at our workshop.
- ✓Drum controller contacts worn or pitted — Colter and Peterson drum controllers operate in switching frequencies of 5-20 times per shift in steel mills and foundries. Contact arcing over years leads to material transfer, pitting, and eventual loss of electrical contact integrity, causing erratic motor speed or complete failure to engage.
- ✓MCC starter coil burned or open-circuit — In Indian textile mills and paper plants, sustained ambient temperatures of 45-50°C combined with high switching duty cycles cause insulation degradation in Colter and Peterson electromagnet coils. Additionally, voltage surges from aging generator sets and poor power quality accelerate winding breakdown.
- ✓Control transformer secondary fuse blown repeatedly — Colter and Peterson MCCs use 115V or 230V control transformers rated for specific load capacity. Oversized contactor banks or addition of extra limit switches increases inrush current beyond transformer rating. Sustained fuse blowing indicates either a short-circuit in the secondary circuit or transformer core saturation from loose laminations.
- ✓Reversing drum fails to reverse or reverses slowly — Colter and Peterson reversing drums (RDC series) have two overlapping contact sets driven by a single rotating cam. Inadequate lubrication of the worm gear, worn synchronization bearings, or bent cam shaft causes the contact sets to shift out of phase, delaying or preventing reversal sequence.
- ✓Thermal overload relay does not trip at rated current — Colter and Peterson TOR series relays use a bimetallic strip calibrated to bend at a specific temperature rise. Over-current heating should trigger a mechanical latch within 10-60 seconds depending on overload severity. Calibration drift occurs due to thermal cycling, corrosion of the bimetallic element, or a stuck mechanical catch.
- ✓Soft starter resistor bank failed or shows high resistance — Colter and Peterson soft starters employ wirewound resistors to limit motor inrush current. In sugar mills, cement plants, and foundries with high dust ingress, moisture and conductive dust bridge resistor connections, causing short-circuits or partial shorts that generate heat and open the resistor element.

Frequently Asked Questions — COLTER AND PETERSON Repairs
Do you repair Colter and Peterson equipment anywhere in India?+
Yes. Synchronics repairs the complete Colter and Peterson product range including drum controllers, motor control centres, relays, soft starters, and control panels. We operate pan-India pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major industrial cities. All repairs are performed in our 10,000 sq ft facility in Vadodara, Gujarat, and turnaround time is typically 5-7 business days for standard repairs.
What is the typical repair cost for a Colter and Peterson drum controller?+
Drum controller repair costs depend on the extent of damage. Contact resurfacing and bearing replacement typically costs INR 8,000-15,000. Full drum assembly replacement or shaft straightening may run INR 20,000-35,000. We provide a free diagnostic assessment and written quotation before undertaking any repair. Many customers prefer refurbishment as it is 40-50% cheaper than original replacement units and extends equipment life by another 10-15 years.
Can Synchronics supply spare parts for Colter and Peterson equipment?+
Yes. We stock commonly replaced components such as contacts, coils, thermal elements, resistor banks, and relay kits for Colter and Peterson drum controllers, MCCs, and soft starters. For discontin disallowed or obsolete parts, Synchronics can often engineer cross-compatible modern alternatives or recommend upgrades that improve reliability. Lead times are typically 7-14 days for in-stock items and 3-4 weeks for special-order components from our USA and European supplier network.
Is it worth repairing a 20-year-old Colter and Peterson MCC or should we replace it?+
Colter and Peterson equipment is built for durability and 20-year-old MCCs can deliver another 10-15 years of service with proper maintenance. Repair is almost always more cost-effective than replacement. However, if the MCC has suffered multiple coil failures, transformer issues, or wiring degradation, it may be due for modernization with upgraded contactors and soft-start technology. Synchronics can advise on a phased retrofit approach that spreads costs while improving energy efficiency and operator safety.
How do I know if my Colter and Peterson drum controller needs urgent repair?+
Warning signs include jerky or hesitant motor speed changes, audible grinding noises from the drum mechanism, inability to reverse direction, and visible arcing at the contact points. If you notice any of these issues, stop operation and contact Synchronics immediately. Continued operation risks motor winding damage, gearbox failure, or operator safety hazards. We offer emergency same-day diagnostics and expedited repair for critical breakdowns affecting production lines across Indian manufacturing sectors.
How do I send my COLTER AND PETERSON 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 COLTER AND PETERSON 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 COLTER AND PETERSON 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 COLTER AND PETERSON 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.
