MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050063 A) filed by MLR Institute Of Technology, Hyderabad, Telangana, on April 20, for 'bldc motor drives for evs.'
Inventor(s) include Mr. P. Jithendar; Mrs. B. Madhuri; Ms. Sabiha Begum; and Mr. R. Someswara Rao.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an electric vehicle drive system employing a Brushless Direct Current (BLDC) motor with Pulse Width Modulation (PWM)-based control for efficient vehicle propulsion. The system comprises a rechargeable battery pack serving as the primary power source, a Battery Management System configured to monitor and protect the battery, a PWM-based BLDC motor controller, and a BLDC motor mechanically coupled to vehicle wheels through a differential mechanism. The motor controller regulates motor speed and torque by varying the PWM duty cycle in response to a throttle input, while rotor position feedback from Hall sensors enables accurate electronic commutation and smooth motor operation. The system further includes a DC-DC converter for supplying regulated low-voltage power to auxiliary loads such as lighting, display units, and control circuits. The integrated operation of the electrical and mechanical subsystems improves energy efficiency, enhances reliability, reduces maintenance requirements, and provides stable vehicle performance, making the proposed drive system suitable for electric vehicle applications."
