BRUSH Product Lines We Repair
Our engineers are trained on the full BRUSH product range. Below are the major product families we service.
Brush DC Motors and Generators
Industrial-grade DC machines for rolling mills, hoists, and cranes. Common issues include brush wear, commutator pitting, field winding insulation breakdown, and bearing degradation under high thermal stress.
Brush AC Alternators and Synchronous Motors
High-capacity alternators for captive power generation and synchronous motors for process industries. Repair challenges include rotor winding shorts, stator core insulation failure, AVR circuit faults, and bearing heating.
Brush Wound-Rotor Motors and Slip-Ring Systems
Slip-ring induction motors used in high-torque applications like crushers and compressors. Typical faults: slip-ring arcing, brush jamming, rotor winding insulation degradation, and secondary circuit intermittency.
Brush Power Rectifiers and Converters
Solid-state rectification and DC conversion systems for mill drive and electroplating applications. Common failures: thyristor gate circuit faults, transformer core saturation, cooling fan malfunction, and control card burnout.
Brush Motor Control Cabinets and Starters
Custom electrical control systems integrating contactors, overload relays, and soft-start logic for Brush-driven equipment. Issues include relay chatter, contactor pitting, thermal sensor drift, and logic circuit PCB dry-joints.
Brush Cooling and Ventilation Systems
Integral and external forced-air and liquid-cooled systems for high-power machines. Repair needs: fan blade fracture, bearing wear, thermal switch failure, coolant pump cavitation, and thermostat malfunction.

Common BRUSH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRUSH equipment arriving at our workshop.
- ✓Brush arcing and commutator surface pitting — Brush wear, incorrect brush pressure, or commutator eccentricity common in Brush DC machines after sustained high-current operation. Indian textile mills and rolling mills often run Brush motors 18-20 hours daily, accelerating mechanical wear.
- ✓Field winding insulation breakdown and ground faults — Thermal stress, moisture ingress, and vibration in high-ambient Indian mill environments degrade Brush motor field winding insulation. Cement and sugar mill dust infiltration accelerates winding degradation in unprotected machines.
- ✓Alternator slip-ring arcing and collector ring carbon transfer — Brush slip degradation, moisture on slip-ring surface, and voltage spikes in Brush synchronous alternators used in captive power plants. Inadequate slip-ring spacing or brush stagger causes collector ring wear in Indian power-generation duty.
- ✓Rotor winding shorted turns and core lamination hotspots — Transient overvoltages, phase imbalances, or mechanical rotor rub in Brush alternators cause rotor winding insulation failure. Indian power supply fluctuations (220V to 290V swings) accelerate rotor heating in heavy-duty alternators.
- ✓Bearing cage fracture and roller misalignment in high-load mills — Brush machines in Indian steel and cement mills experience shock loads and sustained high-speed operation. Bearing preload drift and debris ingestion cause cage wear, leading to catastrophic bearing failure and rotor contact.
- ✓Soft-starter IGBT module thermal failure and gate-drive circuit burnout — Brush soft-starter units in Indian mills suffer from dust-choked heatsinks, inadequate cooling airflow, and gate-drive PCB component degradation from moisture and thermal cycling. Faulty snubber capacitors fail under repetitive inrush current.

Frequently Asked Questions — BRUSH Repairs
Do you repair Brush electrical machines and alternators anywhere in India?+
Yes. Synchronics maintains a full Brush repair capability at our Vadodara headquarters and offers pan-India pickup service. We repair DC and AC motors, alternators, slip-ring machines, rectifiers, and control cabinets across all Indian cities — Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Kolkata, and beyond. Damaged equipment is transported securely, repaired in our facility, tested on our dynamometer, and returned promptly.
What is the typical turnaround time for a Brush DC motor repair at Synchronics?+
Standard Brush motor repairs (brush replacement, commutator dressing, bearing swap) complete in 5-7 working days. Complex rewinds require 12-15 days. Critical downtime situations receive priority handling — we maintain stock of common Brush motor components (brushes, bearings, terminal boxes) and can expedite repairs within 2-3 days. We also offer loaner motors for Indian mills requiring zero production downtime.
How do you test and certify a repaired Brush alternator before returning to the customer?+
Synchronics performs full factory-acceptance testing on every repaired Brush alternator: no-load voltage and frequency check, loaded resistive and reactive load testing on our dynamometer-coupled test stand, insulation resistance testing (megger) at 500V and 1000V, high-potential testing (hipot) at 2x rated voltage for 1 minute, and thermographic imaging to confirm even heating. We provide detailed test reports with all measurements certified by our senior technicians.
Can Synchronics provide spare brushes, bearings, and commutator segments for Brush machines to Indian plants?+
Yes. Synchronics stocks genuine and OEM-equivalent replacement parts for Brush DC and AC machines — carbon brushes (various grades), ball and roller bearings (SKF, FAG), commutator segments, slip-ring brush assemblies, field and armature coils, terminal boxes, and cable glands. We maintain supply relationships with Brush authorized distributors and verified international suppliers. We can source and deliver parts within 3-5 working days across India, with competitive pricing for bulk mill orders.
What training and on-site support does Synchronics provide for Brush equipment maintenance in Indian mills?+
Synchronics offers on-site technical training to plant maintenance staff on Brush motor inspection, preventive maintenance schedules, commutator cleaning, brush pressure setting, and thermal monitoring. We also provide emergency breakdown support — our field engineers have traveled to mills across Gujarat, Maharashtra, and Madhya Pradesh to troubleshoot and perform interim repairs, minimizing production loss. We prepare customized preventive maintenance schedules aligned with your mill's operating hours and duty cycle.
How do I send my BRUSH 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 BRUSH 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 BRUSH 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 BRUSH 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.
