BLDC · EC fans
Star Automations repairs EC (electronically commutated) fans, ebm-papst fans and condenser fan motors used in AHUs, chillers, condensers and cooling systems, at board level. Most EC fan failures are electronics board faults, and we repair the board instead of replacing the whole fan. Star Automations is an independent multi-brand repair company and is not an OEM service centre.
EC fans combine a BLDC motor with built-in electronics. When the electronics fail the whole fan is often replaced.
Control electronics, power supply and start circuit.
Control-signal and speed-feedback faults.
Power stage and thermal faults.
Worn bearings on the rotor.
Modbus and analogue control interface faults.
Board-level repair options.
Star Automations is an independent multi-brand repair company and is not an OEM service centre. Brand names are used only to say which units we repair. Send the model and we confirm repairability before you ship.
Findings come before repair.
Make, model, fault and a photo of the nameplate, on WhatsApp or the request form.
Units should be sent de-energised and disconnected. Pickup can be arranged.
The failed part and the repair options, before any work is approved.
Repair on your approval, then a power-up and functional check on the functions the fault affected.
Printed report with findings, parts replaced and test readings, sent back with the unit.
Bearing noise, vibration and heat are early signs of a failing fan motor. We replace the bearings in EC fans, condenser fan motors and blower motors, check the rotor, balance the rotor or impeller where needed, and test the fan before return. Bearing work is done together with board-level repair, so one visit fixes both.
Send the full type code from the label and the fault. We confirm repairability before you ship.
It depends on the size and fault. The findings report gives both options.

Emergency same-day, urgent 3 working days and standard 7 working days are available where the fault and parts allow. The timeline is stated on the quote.
In most cases the electronics board inside the fan fails, from heat, voltage surges, condensate or humidity, while the motor and impeller are still sound. Bearing wear is the second most common cause.
Yes. We repair the control and power board at component level and test the fan, so you do not have to buy a new fan for a board fault. When a repair is not economical we tell you and quote a replacement.
Yes. We repair EC condenser fan motors and AHU fans for HVAC and chiller service companies, one unit or in batches. See our batch programme page for O&M and HVAC service companies.
Yes. We work from Bengaluru, and units can be couriered or picked up in bulk from other cities.
We hold stock of some ebm-papst fans, for example the 4114 NHH 24 V DC axial fan, subject to availability. Send the model and quantity for a quote.
Yes. We replace worn bearings in EC fans, condenser fan motors and blower motors, then check the rotor and, where needed, balance the rotor or impeller, and test the fan before return. Bearing noise caught early avoids a burnt motor or board.
The electronics board is the weak point of most EC fans. We repair it at component level and test the fan before return, so HVAC service companies do not have to replace the whole fan for a board fault.
We repair EC fans, ebm-papst fans and condenser fan motors in batches for HVAC service and O&M companies, for AHUs, condensers, chillers and cooling towers. Welcome to AMC contractors and facility management teams with many faulty units. See ebm-papst EC fan repair for HVAC and chiller service companies.
New ebm-papst fans, subject to availability, for example the ebm-papst 4114 NHH, 24 V DC axial fan. Send the model and quantity for a quote.
