BEI Product Lines We Repair
Our engineers are trained on the full BEI product range. Below are the major product families we service.
BEI Encoders - Absolute and Incremental
BEI rotary and linear encoders with absolute SSI, CANopen, EtherCAT, and incremental HTL output formats. Common repair issues include bearing wear, contaminated optical surfaces, connector corrosion, and firmware resets after electrical transients or overvoltage spikes.
BEI Resolvers - Synchro and Resolver Feedback
Precision resolver technology for harsh industrial and aerospace environments. Typical faults include stator winding insulation breakdown, rotor mechanical wear, connector pin corrosion, and signal phase loss due to cable damage or EMI interference.
BEI Motion Control Modules
Integrated motion controllers and interface cards for machinery automation. Common repair needs include failed capacitors, relay contact wear, firmware corruption, analog input scaling errors, and CAN/EtherCAT communication timeouts on factory floor installations.
BEI Linear Position Sensors
Magnetostrictive and LVDT-based linear displacement transducers for packaging, textile, and hydraulic machinery. Frequent failures include potentiometer track contamination, cable shielding deterioration, and zero-drift calibration errors from thermal cycling.
BEI LVDT (Linear Variable Differential Transformers)
Rugged LVDT sensors used in molding machines, presses, and heavy machinery across Indian manufacturing. Repair challenges include coil insulation faults after moisture ingress, connector oxidation, and loss of excitation due to supply frequency drift.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common BEI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BEI equipment arriving at our workshop.
- ✓BEI encoder optical surface contamination and signal loss — Dust, oil mist, and moisture ingress on optical disc and sensor windows in high-humidity Indian manufacturing environments. Common in textile mills, paper plants, and food processing units where air filtration is inadequate.
- ✓BEI resolver stator winding insulation breakdown and phase dropout — Thermal cycling, moisture ingress through damaged connectors, and electrical overstress from supply transients. Stator resistance drops to <50 ohms, causing signal phase loss and false position readings in servo systems.
- ✓BEI motion controller capacitor failure and board-level power loss — Electrolytic capacitor dry-out and bulging from sustained high ambient temperatures (40-50°C common in Indian factories). Aged units manufactured before 2015 are particularly vulnerable to ripple current stress.
- ✓BEI linear LVDT coil insulation failure and excitation loss — Moisture absorption in potted coil windings after seal degradation. Common in hydraulic press environments and textile dyeing machinery where steam and humidity levels exceed 80%. Excitation voltage drops from 10V AC to <2V AC.
- ✓BEI encoder zero-crossing error and multiturn count loss — Mechanical shock, vibration-induced bearing preload loss, or firmware corruption after power surge. Encoder reports discontinuous angle steps or resets multiturn counter on line-voltage transients.
- ✓BEI resolver connector corrosion and intermittent signal dropout — Salt-air ingress in coastal Indian plants (Mumbai, Chennai, Visakhapatnam) and moisture in humid regions. Connector pins develop green patina oxide layer, causing contact resistance spikes and resolver signal loss under load.

We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. Same-facility rapid repair turnaround in Vadodara, Gujarat. Typical repair time 5-10 business days for encoder and resolver units.
What BEI encoder models do you repair and what is the typical turnaround time?+
Synchronics repairs all BEI absolute and incremental encoder families including RM35, RH35, RM36, RH45, ECI-3000, and ECI-1000 series across SSI, CANopen, and EtherCAT protocols. Standard turnaround is 5-7 days including optical surface cleaning, bearing service, firmware validation, and full-rotation functional testing. Express 48-hour rush service is available for critical production line stoppages.
Can you repair BEI resolver synchro feedback devices and recalibrate phase angles?+
Yes. Synchronics specializes in BEI resolver repair across 35RES, 45RES, and 100/150-series models. We rewind stator and rotor coils, replace bearings, recalibrate phase angles using precision reference standards, and verify resolver output at zero, 90, 180, and 270 degrees. Insulation testing to 5kV AC confirms coil integrity. All units undergo dynamic testing under load before shipment.
What is the cost of repairing a BEI motion controller with failed capacitors?+
BEI motion controller capacitor replacement typically costs INR 8,000-15,000 depending on board complexity and component count. Costs include parts, labor, full functional testing of motion outputs, CAN/EtherCAT communication verification, and 6-month warranty. Contact Synchronics for free diagnosis and quote - send photos and error codes via email or WhatsApp.
Do you offer BEI encoder calibration certificates and warranty on repaired units?+
Yes. All BEI encoder repairs include factory-standard calibration certificates with SSI/CANopen output verification. We provide 6-month warranty on parts and labor, and 1-year warranty on optical surfaces and bearing assemblies. Synchronics maintains complete traceability of repair work and provides detailed technical reports suitable for ISO 9001 and quality audits.
How do I send my BEI unit for repair?+

What is the cost of repairing a BEI 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 BEI 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 BEI 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.
