DUNKERMOTOREN Equipment We Repair — By Category
DUNKERMOTOREN Product Lines We Repair
Our engineers are trained on the full DUNKERMOTOREN product range. Below are the major product families we service.
DC Brush Motors (SR, DR, SRE series)
Compact permanent-magnet DC motors used in robotics, packaging, and automation. Common issues include brush wear, commutator pitting, bearing degradation, and control board failure due to voltage spikes or moisture ingress.
Brushless DC Motors (EB and EC series)
High-efficiency brushless motors with integrated or external controllers for precise speed and torque control. Failures often involve Hall sensor faults, phase winding shorts, power stage transistor breakdown, or rotor magnet demagnetization.
Stepper and Servo Motor Drives
Closed-loop motion control electronics for stepper and servo motors in CNC machines and automated assembly. Typical faults include encoder connection loss, PWM driver failures, capacitor degradation, and firmware corruption.
Motor Control Modules and I/O Interfaces
Compact control boards for speed regulation, direction reversal, and soft-start functions. Prone to relay contact corrosion, capacitor dry-out, and control signal noise immunity issues in high-EMI industrial environments.

Common DUNKERMOTOREN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DUNKERMOTOREN equipment arriving at our workshop.
- ✓Brush motor commutator pitting and arcing — Dunkermotoren DC brush motors accumulate carbon dust and electrode erosion over 5000-8000 operating hours. Commutator contamination and brush pressure loss cause intermittent electrical contact and brush bounce, triggering arcing and control board noise.
- ✓Hall sensor failure in brushless DC motors — Dunkermotoren EC and EB brushless motors use Hall effect sensors for commutation feedback. Moisture, thermal cycling, and vibration can degrade sensor hall elements or solder joints, causing loss of phase synchronization and motor stall or runaway.
- ✓Power stage transistor and FET failure — Dunkermotoren motor controllers use MOSFET or IGBT power stages to switch current to motor coils. Voltage spikes from inductive load switching, inadequate heatsinking, or surge conditions can damage gate oxide and cause short-circuit failure.
- ✓Encoder feedback signal loss or degradation — Dunkermotoren closed-loop drives depend on rotary encoders or incremental feedback. Cable flexing, connector corrosion, or encoder bearing wear cause intermittent signal dropout, manifesting as position error codes or jerky motion in servo applications.
- ✓Thermal cutout and overtemperature shutdown — Dunkermotoren motors and drives incorporate thermistor or PT100 temperature sensors. Bearing friction increase, control loop instability, or ambient temperature rise above rated limits trigger thermal protection, causing nuisance shutdowns or motor lockout.
- ✓Soft-start capacitor dry-out and voltage regulation failure — Dunkermotoren RMF and RM control modules use electrolytic capacitors for charge storage in soft-start and regulator circuits. Ripple current stress and elevated ambient temperature cause capacitor ESR (equivalent series resistance) to increase and capacitance to drift.

Frequently Asked Questions — DUNKERMOTOREN Repairs
Do you repair Dunkermotoren equipment anywhere in India?+
Yes. Synchronics repairs the full Dunkermotoren DC motor, brushless motor, and drive controller range across all of India. We offer same-day to 48-hour door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and 40+ other cities. All repairs are completed at our main facility in Vadodara, Gujarat, with return shipping included.
What is the typical repair turnaround time for a Dunkermotoren brushless motor drive?+
Standard repair turnaround is 5-7 working days for most Dunkermotoren motor controllers and drives. We prioritize emergency breakdowns — express repair (2-3 days) is available for critical production equipment. Diagnostic assessment is performed within 24 hours of receipt, and customers receive a detailed fault report and repair quote before work begins.
Can Synchronics repair Dunkermotoren motors with damaged connectors or missing firmware?+
Yes. Synchronics restores corroded connectors using precision soldering and contact re-plating. For firmware corruption in Dunkermotoren programmable drives, we recover or reprogram calibration parameters from backed-up configuration files or work with Dunkermotoren representatives to obtain authorized firmware updates. Original firmware integrity is verified before shipment.
Do you offer on-site Dunkermotoren motor repair or diagnostics at our plant?+
We provide on-site diagnostic support and preventive maintenance audits for critical Dunkermotoren installations in Gujarat and nearby states. Our field engineers can perform bore scoping, thermal imaging, vibration analysis, and controller signal capture on-site. For high-volume multi-unit failures, we arrange rapid swap-out with loaner units while your equipment is repaired in our workshop.
What is your warranty on Dunkermotoren drive repairs?+
All Dunkermotoren motor and drive repairs carry a 12-month functional warranty covering defects in repair workmanship and component failure. We use only genuine Dunkermotoren parts, OEM-equivalent components from certified suppliers, or authorized alternatives. Extended warranty packages (24-36 months) are available for critical production motors.
How do I send my DUNKERMOTOREN 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 DUNKERMOTOREN 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 DUNKERMOTOREN 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 DUNKERMOTOREN 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.
