BMT Product Lines We Repair
Our engineers are trained on the full BMT product range. Below are the major product families we service.
CombiControl AMB Systems
BMT's integrated active magnetic bearing controllers for centrifugal compressors and turbomachinery. Controls rotor levitation, damping, and load distribution. Common faults include PID loop instability, sensor drift, and power module failures affecting bearing stiffness.
Power Amplifier Modules (PAM)
Direct current amplifiers driving electromagnetic coils in magnetic bearing stators. Handle 5-50A loads at 48-400V DC. Typical failures: IGBT thermal runaway, capacitor degradation, hall sensor malfunction in rotor position feedback.
Displacement Sensor Units (DSU)
Eddy current proximity sensors measuring rotor clearance and position in real-time. BMT DSUs operate in high-temperature environments near magnetic bearing gaps. Common issues: sensor coil open circuit, calibration drift, noise interference in analog output.
Auxiliary Bearing Assemblies (ABA)
Mechanical backup bearings protecting turbomachinery during magnetic bearing demagnetization or power loss. Heavy radial/thrust loads during rotor drop events. Wear patterns, cage fractures, and preload loss common after emergency landings.
MagLev Rotor Kits
Complete magnetic rotor assemblies with integrated position sensors and coil windings for high-speed applications. Repair involves coil rewinding, magnet bonding, and dynamic balancing to OEM specifications for run-out tolerance <50 microns.
Safety Shutdown Modules (SSM)
Emergency power-down systems and bearing touchdown detection units. Trigger auxiliary bearing engagement when primary magnetic levitation fails. Failure modes include relay chatter, solenoid coil burnout, and logic board watchdog resets.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common BMT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BMT equipment arriving at our workshop.
- ✓AMB controller loss of rotor position feedback — Displacement sensor coil intermittent connection, eddy current probe gap contamination by iron filings, or sensor cable shielding failure causing noise immunity degradation in high-EMI industrial environments.
- ✓Power amplifier thermal shutdown during normal operation — IGBT junction temperature exceeding 150°C due to aluminium heatsink bond-line degradation, thermal paste dry-out over 3-5 years, or PWM switching frequency drift causing core losses in output filter inductors.
- ✓Rotor magnetic levitation instability and hunting oscillations — PID loop tuning parameters (Kp, Ki, Kd) shifted due to firmware corruption, mechanical stiffness change from bearing coil winding degradation, or cross-coupling between X-Y radial axes in non-isotropic rotor designs.
- ✓Auxiliary bearing cage fracture and roller skidding — Excessive radial/thrust loads during rotor emergency landing after magnetic bearing power loss, lubrication starvation in sealed cage designs, or pre-existing material defects in backup roller bearings under 3000+ rotations per minute impacts.
- ✓Sensor calibration drift causing bearing stiffness variation — Analog offset voltage creep in displacement sensor amplifier circuits, temperature coefficient nonlinearity in eddy current probe output over seasonal Indian temperature swings (15-45°C), or ADC resolution loss from supply voltage noise.
- ✓Safety shutdown module solenoid coil failure and no touchdown detection — Solenoid coil insulation breakdown from thermal cycling, mechanical valve plunger seizure from corrosion or mineral deposits in hydraulic pilot lines, or relay contact arcing when safety shutdown triggers at bearing landing impact.

Frequently Asked Questions — BMT Repairs
Do you repair BMT equipment anywhere in India?+
Yes. Synchronics is an authorized BMT repair partner with complete stock of replacement modules — CombiControl systems, power amplifiers, displacement sensors, and auxiliary bearings. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all tier-1 cities. All repairs completed in our Vadodara, Gujarat facility with factory-equivalent test benches for magnetic bearing systems.
How do you test BMT magnetic bearing controllers after repair?+
Synchronics uses dedicated AMB test rigs simulating real rotor dynamics. We perform PID loop stability analysis with frequency response testing, verify power amplifier output under full-load conditions at 40A+ steady state, and validate displacement sensor linearity across the full 0-10mm bearing gap. All units run 24-hour burn-in tests matching Indian thermal power plant duty cycles before return to customer.
What is the typical turnaround time for BMT CombiControl repairs?+
Standard repair turnaround is 5-7 working days for module replacement and basic calibration. Complex firmware issues or multi-channel controller failures may require 10-14 days including extended testing. We offer 48-hour express repair for emergency outages at thermal power plants and refineries — parts diagnosis within 24 hours. Synchronics maintains emergency stock of common BMT modules to minimize downtime.
Do you handle BMT rotor rewinding and magnetic bearing coil refurbishment?+
Yes. Synchronics performs complete MagLev rotor coil rewinding to OEM winding diagrams, magnet bonding with controlled epoxy cure, and dynamic rotor balancing to <50 micron run-out specifications. We service rotor assemblies from thermal power plant turbines and refinery compressors — all work done under cleanroom conditions with traceability documentation for safety-critical equipment.
Can you provide BMT bearing health monitoring and predictive maintenance support?+
Yes. Beyond repair, Synchronics offers condition-based monitoring services for BMT-equipped machinery. We analyze displacement sensor trends, vibration signatures, and power amplifier thermal cycles to predict bearing stiffness loss or impending auxiliary bearing landing. Our Indian power plant and refinery clients receive monthly health reports with maintenance recommendations, helping avoid unplanned shutdowns of critical rotating equipment.
How do I send my BMT 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 BMT 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 BMT 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 BMT 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.
