Building Low-Cost High-Efficiency BLDC Motors for Next-Gen Robotics
How intelligent design, localized supply chains, and algorithmic compensation are driving down the cost of premium BLDC motors.
Agastya Sharma is the Lead Embedded Systems Engineer at Entlar, where he owns the full firmware stack — from gate driver initialization to closed-loop FOC algorithms. He has spent over eight years in motor control, power electronics, and real-time embedded systems. Before Entlar, he worked on industrial servo drives and EV powertrain controllers. At Entlar, Agastya designed the sensorless startup algorithm, the adaptive PID gain scheduler, and the BLE communication protocol used in Entlar's smart fan platform. He holds a B.Tech in Electronics Engineering from IIT Bombay and is deeply interested in the intersection of control theory and embedded firmware.

Brushless DC motors are becoming the de facto actuator choice for modern robotics. We examine why BLDC technology is poised to dominate the next decade of robotic systems — from collaborative arms to autonomous mobile robots.
Artificial intelligence is entering the motor control loop — not as a buzzword, but as a set of practical, deployable techniques that are measurably improving efficiency, reliability, and precision in electric motor systems.
Hall sensors and encoders have been the standard for BLDC position sensing for decades. Sensorless control promises the same performance without the failure modes. Is the technology ready for mainstream adoption?
Most ceiling fan manufacturers focus on motor speed. We focused on aerodynamics first. Here is what the fluid dynamics actually tell us about efficient air delivery in residential spaces.
Designing a PCB for a BLDC motor controller is not like designing digital logic. High currents, fast switching transients, and extreme thermal demands require discipline at every stage of the design process.
Building a hardware startup in India is harder than building a software startup — and more rewarding. Here is an honest account of the journey from first prototype to scalable product, based on Entlar's own experience.
