The Future of BLDC Motors in Robotics (2026 & Beyond)
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.
How AI is Revolutionizing Motor Control Systems
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.
Sensorless BLDC Motor Control: The Next Big Thing?
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?
Sensorless BLDC Startup: Zero-Crossing Detection Without Hall Sensors
Hall-effect sensors are a common failure point in BLDC motors. We designed our fan to start reliably from standstill using only back-EMF zero-crossing detection — and the maths behind it is elegant.
PCB Design for High-Performance Motor Controllers: Best Practices
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.
Designing Energy-Efficient Motors for Sustainable Engineering
Electric motors consume over 45% of global electricity. Designing more efficient motors is not just good engineering — it is one of the highest-leverage interventions available for reducing global energy consumption.
From Prototype to Product: How to Build a Robotics Startup in India
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.
