EEAB Product Lines We Repair
Our engineers are trained on the full EEAB product range. Below are the major product families we service.
EEAB Standard Asynchronous Motors
Three-phase induction motors (IE1 to IE4 efficiency classes) in frame sizes 71-280, 50/60Hz dual voltage. Common issues include winding insulation breakdown, bearing wear, and rotor bar fractures from thermal stress or load shock.
EEAB High-Efficiency IE3/IE4 Motors
Premium efficiency motors with reduced copper losses and advanced cooling for energy-critical applications. Prone to capacitive voltage rise, PWM stress on windings when driven by VFDs, and thermal management issues in tropical Indian climates.
EEAB Wound-Rotor (Slip-Ring) Motors
Double-cage and wound-rotor designs for high starting torque applications in crushers, mills, and hoists. Repair challenges include slip-ring carbon tracking, brush wear, rotor winding faults, and control rheostat maintenance.
EEAB Synchronous Generators
AC generators for captive power, backup systems, and renewable integration in Indian industrial estates. Common faults: excitation system failure, stator winding ground faults, bearing lubrication loss, and rotor field winding insulation degradation.
EEAB Compact Flange-Mounted Motors
Direct-coupled motors for pumps, fans, compressors with SAE or metric flanges. Failure modes include mechanical seal wear, misalignment-induced bearing failure, and thermal overload in cooling tower applications.
EEAB Premium Moisture-Resistant Motors
Sealed and tropical-rated motors for sugar mills, paper plants, and chemical industries. Typical issues: ingress of moisture and corrosive gases into winding insulation, bearing corrosion, and thermal class degradation in humid environments.

Common EEAB Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EEAB equipment arriving at our workshop.
- ✓Stator winding insulation breakdown and phase-to-earth faults — EEAB motors in Indian mills and crushers experience prolonged thermal stress from overload, inadequate ventilation, and moisture ingress in coastal/humid regions. Insulation aging is accelerated by tropical ambient temperatures and industrial dust contamination.
- ✓Rotor bar fractures and end-ring failures — High starting current transients, locked-rotor conditions during jams (common in sugar mills and stone crushers), and thermal cycling cause micro-cracks in aluminium rotor bars. End-ring joints fail under mechanical stress, causing phase imbalance and severe vibration.
- ✓Bearing seizure and lubrication failure — Contaminated lubricant (water ingress, dust from unguarded bearings), inadequate grease re-lubrication intervals, and bearing wear on EEAB motors in textile spindles and pump applications lead to raceway spalling and seizure.
- ✓VFD-induced winding stress and partial discharge — EEAB IE3/IE4 motors retrofitted with modern PWM drives (Danfoss, ABB, Schneider) experience dv/dt transients and high-frequency overvoltage spikes. Insulation stress accumulates rapidly in tropical climates, causing corona discharge and tracking.
- ✓Slip-ring carbon tracking and brush wear on wound-rotor motors — EEAB wound-rotor motors in mill cranes and hoist duty cycles experience repetitive arcing at slip-rings due to brush chatter, moisture-induced resistance variation, and improper brush spring tension. Carbon brush dust accelerates tracking on the ring surface.
- ✓Generator excitation system failure and loss of field condition — EEAB synchronous generators in Indian industrial captive plants experience exciter winding open circuits, failed voltage regulators (often from power surges), and loss of permanent magnet in brushless exciters during grid faults or improper paralleling.

Frequently Asked Questions — EEAB Repairs
Do you repair EEAB equipment anywhere in India?+
Yes. Synchronics repairs the complete EEAB product range—asynchronous motors (IE1 to IE4), wound-rotor motors, synchronous generators, and compact flange-mounted units. We offer pan-India door-to-door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other industrial cities, with centralized repair at our state-of-the-art facility in Vadodara, Gujarat.
How do you test EEAB motors for hidden faults before rewinding?+
Synchronics employs multi-stage diagnostics for EEAB motors: (1) Megohmmeter insulation resistance testing at 500V/1000V DC, (2) Very Low Frequency (VLF) partial discharge analysis to detect insulation degradation, (3) Thermal imaging to identify hot-spot winding areas, (4) Vibration signature analysis on bearings, and (5) Rotor bar integrity testing via thermal camera during locked-rotor condition. This ensures we identify root causes and prevent recurrence.
What is your turnaround time for EEAB motor repair in India?+
Standard EEAB motor repair (bearing replacement, cleaning, and test) takes 5-7 working days. Complete rewinding of stator or rotor requires 12-15 days including cure time for varnish and thermal cycling validation. Synchronous generators and wound-rotor motors may require 18-20 days due to exciter and slip-ring work. We provide daily status updates and offer express service for critical production runs at a premium.
Do you stock EEAB spare parts and replacement motors in India?+
Synchronics maintains a curated inventory of high-turnover EEAB spares: sealed bearings (SKF/FAG equivalents), carbon brushes, slip-rings, exciter components, and thermal class insulation materials. We also hold refurbished EEAB motors in common frame sizes (90-180) for emergency exchange. Custom EEAB parts are sourced from our Swedish network within 10-14 days.
Can Synchronics retrofit EEAB motors with VFD-compatible insulation for modern drives?+
Absolutely. Many Indian sugar mills and cement plants are upgrading EEAB motors from fixed-speed to variable-frequency drive (VFD) duty. Synchronics rewires EEAB motors with PWM-rated insulation systems, installs dv/dt filters or line reactors, and performs impulse voltage breakdown testing. We also tune VFD parameters (switching frequency, ramp time) for optimal compatibility and energy savings. Full documentation and warranty are provided.
How do I send my EEAB 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 EEAB 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 EEAB 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 EEAB 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.
