MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541121484 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 4, 2025, for 'design and implementation af an iot assisted closed loop bldc motor drive using a mosfet based voltage source inverter with pwm techiques.'
Inventor(s) include M Manjula; R Vignesh; T Madhuvanan; and P Dharanya.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The proposed innovation presents the design and implementation of an IoT-assisted closed loop BLDC motor drive that integrates advanced power electronics, control techniques, and loT connectivity for intelligent and efficient motor control. The system employs a MOSFET-based Voltage Source Inverter (VSl) that efficiently converts DC power into variable AC output with low conduction losses and high switching speed. Using Pulse Width Modulation (PWM) techniques, the inverter precisely regulates the voltage and current supplied to the BLDC motor, ensuring smooth commutation, reduced torque ripple, and high dynamic response. A closed-loop feedback mechanism with Hall Effect sensors continuously measures the actual motor speed and compares it with the reference speed set by the user. The microcontroller processes this feedback and automatically adjusts the PWM duty cycle to maintain constant speed under changing load or supply conditions. The integration of loT technology enables real-time data monitoring, remote control, and performance analysis through cloud-based dashboards or mobile applications, enhancing user convenience and system intelligence. Additionally, the system incorporates fault detection and protection features such as overcurrent, overvoltage, and overheating protection to ensure safe and reliable operation. The proposed model offers high efficiency, compact design, and low maintenance, making it a cost-effective and scalable solution for a wide range of applications including industrial automation, electric vehicles, HVAC systems, renewable energy, and smart home technologies. Overall, this innovation bridges the gap between conventional motor control systems and modern smart technologies by providing an energy-efficient, remotely accessible, and intelligent BLDC motor drive system."
