Synchronics Electronics has extensive experience servicing ACEM motor control systems, soft-starters, and associated automation hardware throughout India. Our 180-plus engineers understand ACEM's engineering philosophy and the specific failure modes that emerge in hot, humid Indian industrial environments. Whether diagnosing thermal overload faults in ACEM soft-starters or repairing power electronics in ACEM motor controllers, we combine technical depth with rapid turnaround to minimize your production downtime.
Deep technical expertise in ACEM soft-starters, motor controllers, and drive troubleshooting across Indian industries.
ACEM Product Lines We Repair
Our engineers are trained on the full ACEM product range. Below are the major product families we service.
ACEM Soft-Starters (SMS Series)
ACEM soft-starters reduce inrush current and mechanical stress on motors during start-up, extending motor life and reducing power bill spikes. Common faults include thyristor failures, over-temperature shutdown, and loss of ramp control signal.
ACEM Three-Phase AC Motors (IE3 Efficiency Class)
High-efficiency IE3-rated motors designed for continuous duty in mills, compressor drives, and pump applications. Failures typically involve bearing wear, winding insulation breakdown due to moisture ingress, and shaft surface spalling under radial load.
ACEM Motor Protection & Control Relay Units (CPR Series)
Compact protection relays for motor circuits offering thermal overload, phase loss, and earth fault detection. Repair issues centre on faulty sensing circuits, relay contact welding, and reset mechanism seizure in harsh environments.
ACEM Power Capacitor Banks (for Power Factor Correction)
Fixed and switched capacitor assemblies used alongside ACEM motors to improve power factor and reduce reactive power penalties. Failures include capacitor element bulging, internal discharge paths, and contactor arcing damage.
ACEM Terminal Boxes & Control Enclosures
Custom-built IP55 / IP65 stainless steel enclosures housing ACEM soft-starters and motor controllers. Common issues include moisture condensation inside due to thermal cycling, corrosion of internal copper busbars, and loose terminal connections causing arcing.

Common ACEM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ACEM equipment arriving at our workshop.
- ✓ACEM soft-starter thyristor open or short circuit — Voltage transients from reactive loads (pumps, compressors) or poor DC bus filtering in humid Indian mills exceed thyristor voltage rating. Thermal cycling exacerbates solder joint fatigue.
- ✓ACEM motor bearing outer race spalling with audible grinding — Misalignment between motor shaft and driven load, combined with moisture-induced corrosion of bearing races in poorly sealed IE3 motor housings common in coastal Indian facilities.
- ✓ACEM CPR relay contacts stuck or welded, motor cannot be switched off — Arc tracking across contact surfaces caused by repetitive switching of inrush current without soft-starter; moisture and dust inside the relay housing accelerate contact degradation.
- ✓ACEM soft-starter temperature sensor fault — false over-temperature alarm — Faulty PT100 RTD element inside the heatsink, or corroded sensor connector pins due to condensation. PLC reads erratic temperature readings causing unnecessary soft-starter shutdown.
- ✓ACEM capacitor bank unit internal discharge, loss of reactive power correction — Capacitor dielectric degradation under sustained overvoltage (mains unstable in Indian industrial areas), or internal element short-to-case causing unit isolation by contactor.
- ✓ACEM motor winding phase-to-earth insulation breakdown — earth fault trip — Moisture ingress through non-sealed terminal box or damaged cable gland; salt spray corrosion in coastal plants. Wet insulation creates low-impedance path to motor frame.

Frequently Asked Questions — ACEM Repairs
Do you repair ACEM equipment anywhere in India?+
Yes. Synchronics repairs the complete ACEM product range — soft-starters, three-phase motors, protection relays, capacitor banks, and custom enclosures. We offer PAN India door pickup and logistics from our main service facility in Vadodara, Gujarat, with satellite presence in Mumbai, Delhi, Pune, Bangalore, and Chennai. Most repairs are completed within 7-10 working days.
What is the turnaround time for an ACEM soft-starter repair or replacement?+
Standard repair turnaround is 5-7 working days for diagnostics, parts procurement, and testing. Emergency repairs are expedited to 48 hours if spares are in stock. We maintain a buffer inventory of common ACEM soft-starter modules (thyristor bridges, gate drive boards, heatsink assemblies) to minimize lead time for mills running continuous shift patterns.
Can you repair ACEM IE3 motors with winding insulation faults, or do they need rewinding?+
Synchronics performs non-destructive megohm and partial discharge testing to assess insulation integrity. Minor moisture contamination is treated by controlled oven drying (60-80°C) followed by vacuum pressure impregnation (VPI) using ACEM-approved polyester resin. If insulation puncture is confirmed, we offer full rewinding in-house using OEM-spec magnet wire, ensuring restored efficiency and bearing loads. We guarantee rewound motors to ACEM original performance.
Why do ACEM soft-starters fail prematurely in Indian textile mills?+
Textile mills subject ACEM soft-starters to extreme thermal stress due to: (1) dusty, humid environment causing capacitor and heatsink fouling; (2) frequent line voltage sag and transients from other heavy starting loads on the same mains feeder; (3) poor enclosure ventilation leading to internal temperatures exceeding 60°C. Synchronics recommends scheduled thermography inspection every 12 months and upgrading filter-ventilation in control enclosures to reduce junction temperature and extend thyristor life.
Do you stock ACEM spare parts or must I order from Italy?+
Synchronics maintains a curated spare parts inventory for ACEM soft-starter modules, control boards, and sensor elements based on failure pattern analysis of repairs we perform. For obsolete ACEM models or custom items, we coordinate directly with ACEM Italy or authorized stockists to minimize delivery time. We also reverse-engineer and manufacture functional replacements for discontinued subassemblies, offering cost savings of 30-40% versus OEM sourcing.
How do I send my ACEM 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 ACEM 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 ACEM 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 ACEM 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.
