inergy BLDC motor solutions
BLDC motor driver ICs, MOSFETs, gate drivers and tuning support in India
Star Automations is the inergy (Taiwan) India partner, agreement in progress. inergy makes BLDC motor driver ICs, intelligent power modules, gate drivers, power MOSFETs and Hall sensors, and tunes motor drives remotely. Star adds the India side: coordination, samples, tuning sessions, engineer training and failure analysis of field returns. Our focus is the replacement and alternative-source market, with engineering support in India.
Who this page is for
- Fan makers moving ceiling, pedestal, exhaust and kitchen-hood fans from induction to BLDC
- Air cooler, HVAC and EC fan makers who need a driver for AC-to-BLDC conversion
- Server, telecom and data-center cooling makers working at 12 V, 24 V and 48 V
- EV controller, drone and power-tool teams that need a low-voltage BLDC driver to evaluate
- Importers, distributors, ODM and EMS companies looking for a second source for motor driver ICs
The problem Indian teams run into
Indian appliance and fan makers are under pressure from three sides: efficiency labelling pushes designs towards BLDC, buyers want lower cost, and many teams depend on one overseas supplier for the control IC. A small in-house team often has the hardware ready but loses weeks tuning start-up, noise and EMI on the motor.
Overseas IC makers rarely provide an engineer who works your hours, understands your motor, and can sit in your lab. That gap is where projects slip from months to quarters.
An alternative source for the replacement market, with engineering behind it
Indian fan, cooler and appliance makers usually buy BLDC driver ICs through multi-brand distributors. That works for catalogue parts, but it rarely comes with help on your own motor: start-up, noise, EMI, or the failed boards coming back from the field. Star Automations adds a dedicated BLDC desk for two groups.
Replacement market
Service networks, repairers and OEM spare-parts teams who need a supported alternative when a BLDC controller or driver IC fails, or when the original source is hard to get. We start from what fails in the field, because Star has repaired motors, drives and electronics for 25+ years.
Alternative source for OEMs
Makers who want a second source that comes with reference designs, remote tuning and an engineer who answers in Indian working hours.
Make in India: inergy's ICs are made by inergy in Taiwan. What we bring to India is the engineering around them: design support, tuning, testing, training and service, so Indian manufacturers can build, tune and support their own controllers locally and rely less on imported finished controllers. Where a part is used to replace an original, compatibility is checked case by case. We do not claim drop-in equivalence.

Design notes before you start
- Start with the supply: mains-powered designs need an HV driver and isolation planning, while DC designs up to 48 V can use the low-voltage SoCs.
- Decide sensorless or Hall early. It changes the BOM, the wiring harness and the start-up behaviour under load.
- Plan protections from day one: overvoltage, overcurrent, overtemperature and stall recovery all need tuning on the real motor.
- Budget time for EMI and acoustic work. These are the usual reasons a BLDC project misses its schedule.
What Star Automations adds in India
- Local coordination between your engineers and inergy's FAE team, in Indian working hours
- Sample and evaluation-kit requests handled through one Indian contact
- Help booking and running inergy's remote motor fine-tune sessions
- Practical training for your service engineers on BLDC drive troubleshooting
- Failure analysis and component-level repair of field-returned drives and motors, backed by 25+ years of motor and drive repair experience
From sample to mass production
1. Share your requirement
Send company name, application, expected annual volume, the driver IC or controller you use today, and your target date. A short form on WhatsApp is enough.
2. Part selection and design review
We match your application to devices in inergy's published IC library and check which reference-design files (schematic, BOM, Gerber, firmware) are available for it. Availability of files for a given design: confirmed per enquiry.
3. Sample and evaluation
We arrange samples or an evaluation board for your bench. Sample quantities and lead time: confirmed per enquiry.
4. Remote motor fine-tune
inergy states that its FAEs tune the motor drive live over a remote link, book a slot within 48 hours of a request and return the parameter set, updated firmware and a session report the same day. Your lab engineer joins with a UART dongle, the motor control tool and AnyDesk or UltraViewer. Star coordinates the booking and sits in on the session.
5. EVT and DVT validation
Check protections (overvoltage, overcurrent, overtemperature), EMI and acoustic behaviour, start-up and stall recovery on your actual motor and PCB, not only on the reference board.
6. Mass-production readiness
Freeze firmware and BOM, confirm supply, and set up a loop for field returns. Star's repair and failure-analysis team can examine returned units so findings go back into the design.
