BRUSH ELECTRICAL Product Lines We Repair
Our engineers are trained on the full BRUSH ELECTRICAL product range. Below are the major product families we service.
Brush DC Motor Series
Industrial-grade direct current motors ranging from fractional HP to several hundred kW, used in rolling mills, crushers, and process machinery. Common repairs involve brush wear, commutator damage, armature winding faults, and bearing degradation.
Brush AC Induction Motors
Three-phase AC motors for factory, pump, compressor, and conveyor drives. Brush AC motors are engineered for Indian ambient conditions and industrial voltage fluctuations. Repair issues include stator winding insulation breakdown, rotor bar cracking, and bearing failures.
Brush Servo Drive Systems
Precision motor control electronics for closed-loop servo positioning, velocity feedback, and torque regulation in textile machinery, packaging lines, and automation. Servo drive failures stem from power module burnout, encoder signal loss, and control board capacitor degradation.
Brush Wound-Rotor Motors
Slip-ring motors with external rotor resistance control for soft-starting and speed variation in crushers, pumps, and mills across Indian quarries and mineral processing plants. Typical faults include slip-ring wear, brush track corrosion, and rotor winding short circuits.
Brush Generator and Excitation Systems
DC and AC generators with voltage regulation and excitation control for standby power, wind turbine systems, and hydro applications. Generator repairs address field winding faults, voltage regulator malfunction, and brush-gear deterioration.
Brush Motor Control Panels and Starters
Integrated motor control units including contactor banks, soft-starters, and overload protection for factory automation and Indian industrial switchgear installations. Panel repairs involve PCB component replacement, relay calibration, and thermal sensor diagnostics.

Common BRUSH ELECTRICAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRUSH ELECTRICAL equipment arriving at our workshop.
- ✓Brush wear and commutator pitting in DC motors — Brush Electrical DC machines operate under heavy industrial load in Indian plants. Continuous arcing at the commutator surface erodes brush material and creates surface irregularities, causing intermittent electrical contact and sparking.
- ✓Stator winding insulation breakdown and phase-to-phase shorts — Brush Electrical AC motors in Indian plants face thermal stress from ambient temperatures exceeding 45°C, moisture ingress, and voltage spikes. Insulation degradation leads to phase faults, earth faults, and complete motor burnout if unrepaired.
- ✓Encoder signal loss in Brush servo drive systems — Brush servo motors with incremental or absolute encoders lose position feedback due to connector corrosion, cable flexing damage, or encoder bearing wear. This causes servo loop instability, fault codes, and uncontrolled motor motion in packaging and textile machinery.
- ✓Power module and IGBT failure in Brush servo controllers — Brush Electrical IGBT-based servo drives degrade when exposed to high ambient temperatures, dust accumulation on heatsinks, or supply voltage spikes. Power modules short internally, causing DC link collapse and loss of motor control output.
- ✓Slip-ring and brush track corrosion in wound-rotor motors — Brush Electrical wound-rotor motors in Indian mills and crushers experience slip-ring surface oxidation and brush track buildup from copper dust and contamination. High contact resistance develops, reducing external rotor resistance effectiveness and causing overheating.
- ✓Voltage regulator drift and excitation failure in Brush generators — Brush Electrical generator voltage regulators drift out of calibration due to component aging, temperature variation across Indian seasons, or transient voltage spikes. Output voltage becomes unstable, damaging connected equipment and causing load-shedding.

Absolutely. Our 180+ engineers specialise in rewinding Brush Electrical stators and rotors to factory specifications using heritage winding diagrams and OEM insulation systems. We perform vacuum-pressure impregnation, high-pot testing to 2.5 kV, and dynamometer testing to verify performance before dispatch. Indian manufacturing plants trust our Brush Electrical rewind quality for critical machines.
What is the typical repair cost and timeline for a Brush servo drive controller?+
Brush servo controller repair costs range from Rs 8,000 to Rs 35,000 depending on fault severity — power module replacement, PCB repair, firmware reload, or full recalibration. Turnaround is 5-7 working days for most faults. Synchronics offers a 6-month warranty on servo drive repairs and can supply loaner controllers to minimise your production loss.
Do you repair Brush slip-ring motors used in Indian crushers and mills?+
Yes. Synchronics has extensive experience repairing Brush wound-rotor and slip-ring motors used in quarries, mineral processing plants, sugar mills, and cement factories across India. We clean and polish slip-rings, replace brushes and brush-gear, repair rotor resistance grids, and test insulation to ground. Our commutator lathe can resurface rings up to 1.5 metre diameter.
What warranty does Synchronics offer on Brush Electrical motor repairs?+
All Brush Electrical motor rewinding and repairs come with a 12-month performance warranty covering material and workmanship. We warrant that motors will perform to OEM specifications under normal operating conditions. Servo drive repairs carry a 6-month parts and labour warranty. Warranty excludes misuse, overload, and external damage. Terms and conditions apply.
How do I send my BRUSH ELECTRICAL unit for repair?+

What is the cost of repairing a BRUSH ELECTRICAL 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 ELECTRICAL 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 ELECTRICAL 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.
