HAWKER SIDDELEY Repair Services India
Hawker Siddeley was a legendary British aerospace and industrial conglomerate that designed and manufactured advanced control systems, electrical equipment, and automation solutions for defence, aviation, and heavy industry. Though the group was restructured, its industrial electronics legacy—particularly in motion control, power distribution, and process automation—remains embedded in thousands of Indian manufacturing plants, refineries, and power stations built during the 1970s-1990s.

HAWKER SIDDELEY Product Lines We Repair
Our engineers are trained on the full HAWKER SIDDELEY product range. Below are the major product families we service.
Hawker Siddeley AC Drive Systems
Robust three-phase AC motor drives used in Indian textile mills, cement plants, and paper machinery. Common issues include thermal faults, capacitor degradation, and firing circuit failures on older SCR/IGBT modules.
Hawker Siddeley DC Motor Controllers
Field-proven DC regenerative drives for steel mill rolling stands, winding machines, and precision spindle applications. Prone to armature ripple noise, field weakening circuit faults, and brush/commutator wear.
Hawker Siddeley Servo Amplifiers
Closed-loop servo motion control for textile machinery, packaging lines, and CNC retrofits. Failures include encoder interface errors, PWM switching faults, and analog feedback signal conditioning issues.
Hawker Siddeley Power Supply Units
Multi-output industrial PSUs supplying logic circuits, solenoids, and field devices in automation systems. Frequent problems: transformer saturation, rectifier diode failure, and output voltage regulation drift.
Hawker Siddeley Logic Control Modules
Relay-based and early transistor-based control logic for machinery interlocks and process sequencing. Age-related issues: contact corrosion, relay chatter, and PCB dry joints on vintage boards.
Hawker Siddeley Soft Starter Units
Solid-state soft starters for reducing inrush current in large motors across Indian pump stations and compressor facilities. Common failures: thyristor leakage, phase-loss detection circuit faults, and thermal overload sensor drift.

Common HAWKER SIDDELEY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HAWKER SIDDELEY equipment arriving at our workshop.
- ✓Hawker Siddeley drive thermal shutdown / overtemperature lockout — Electrolytic capacitors dried out or thermistor sensor failure in aging HS drives. Heat sink compound degradation and fan motor wear reduce cooling efficiency in tropical Indian climates.
- ✓Hawker Siddeley servo amplifier encoder loss / position feedback error — Connector corrosion on encoder input pins, shielded cable degradation, or optical encoder sensor contamination from mill dust and humidity. Common in textile and paper machinery retrofits.
- ✓Hawker Siddeley DC drive armature ripple noise / commutation fault — Worn brushes and commutator scoring on legacy DC motors, uneven brush pressure springs, or weak permanent magnets. Prevalent in 30+ year old HS units on steel mill stands.
- ✓Hawker Siddeley power supply unit output voltage drift / regulation failure — Transformer winding insulation breakdown from heat stress, zener regulator IC failure, feedback divider resistor drift, or secondary winding copper loss in older PSU designs.
- ✓Hawker Siddeley soft starter thyristor leakage / gate circuit malfunction — Thyristor junction leakage due to moisture ingress or gate drive transformer saturation. Surge diodes fail under inrush transients common in Indian pump station start-stop cycles.
- ✓Hawker Siddeley logic controller relay chatter / intermittent contact adhesion — Relay contact wear and oxidation, weak spring tension, or mechanical vibration in mill environments. Coil winding resistance increases with age, reducing magnetic pull-in force.
