CROMPTON GREAVES LIMITED Equipment We Repair — By Category
CROMPTON GREAVES LIMITED Product Lines We Repair
Our engineers are trained on the full CROMPTON GREAVES LIMITED product range. Below are the major product families we service.
AC Induction Motors
Crompton Greaves three-phase AC motors for pumps, fans, compressors and process equipment. Common issues include bearing failures, winding insulation breakdown, and rotor cage damage. Repair involves rewinding, bearing replacement, and dynamic balancing.
DC Motors and Generators
Crompton Greaves DC machines for textile mills, paper plants, and precision machinery. Typical faults include commutator wear, brush arcing, field winding open circuits, and bearing seizure. Synchronics restores commutator geometry and rewinds field coils.
Soft Starters and VFDs
Crompton Greaves electronic soft starters reduce inrush current; VFDs offer variable speed control for energy savings. Issues include thyristor failures, control card faults, and firmware corruption. Synchronics handles board-level repair and firmware restoration.
Control and Automation Panels
Crompton Greaves custom control panels for cement mills, steel plants, and sugar factories. Faults include contactor wear, timer relay failures, and control transformer burnout. Synchronics repairs individual components and replaces failed modules.
Synchronous Motors
Crompton Greaves synchronous motors for constant-speed applications in compressors and mills. Common failures involve exciter winding open circuits, rotor winding faults, and pole piece cracking. Synchronics performs field winding repairs and exciter restoration.
Motor Starters and Protection Relays
Crompton Greaves DOL starters, star-delta starters, and overload protection relays for industrial machinery protection. Failures include contact erosion, coil burnout, and thermal element degradation. Synchronics replaces coils and restores contact surfaces.

Common CROMPTON GREAVES LIMITED Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CROMPTON GREAVES LIMITED equipment arriving at our workshop.
- ✓AC motor winding insulation breakdown — Crompton Greaves AC motors operate in high-temperature textile and cement environments where moisture and heat degrade insulation. Phase-to-phase or phase-to-earth shorts develop after 8-12 years, especially in non-IE3 older models.
- ✓Soft starter thyristor gate drive failure — Crompton Greaves soft starters experience gate driver IC failures due to voltage transients, thermal stress, and PCB aging. Devices stop commutating, causing motor stalls and nuisance trips in sugar mill applications.
- ✓VFD capacitor bank ESR increase and voltage instability — Crompton Greaves VFD electrolytic capacitors in the DC bus degrade under continuous operation in Indian industrial environments — high ambient, humidity, and ripple current stress cause ESR rise and voltage sag.
- ✓Commutator wear and brush sparking in DC motors — Crompton Greaves DC motors in paper mills and textile machinery experience rapid commutator mica undercutting and brush wear due to dust, vibration, and high current ripple. Arcing develops after 5-7 years.
- ✓Motor contactor coil burnout in control panels — Crompton Greaves panel contactors in cement kiln and steel plant duty cycles experience repeated thermal shock and voltage surges. Coils open-circuit, preventing motor starts across entire production lines.
- ✓Synchronous motor exciter winding open circuit — Crompton Greaves high-speed synchronous motors used in mill drive applications develop open circuits in exciter windings due to vibration loosening connections and thermal cycling. Motor loses excitation and falls out of step.
