MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611007380 A) filed by Motorama Ev Private Limited, Noida, Uttar Pradesh, on Jan. 25, for 'magnetic eccentricity compensation drive for brushless dc motors.'
Inventor(s) include Abhishek Gupta.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "Disclosed is a motor-drive apparatus and method for compensating magnetic eccentricity in a brushless DC motor. The apparatus uses a multi-phase inverter supplying stator windings from a DC supply, a rotor-position sensing unit generating a mechanical angle signal, and an electrical response sensing circuit producing an electrical asymmetry signal correlated to rotor position. A memory stores a rotational magnetic imbalance profile indexed to mechanical rotor angle. A compensation waveform generator derives a corrective current component from the stored profile and the mechanical angle signal. A current summation interface superimposes the corrective current component onto a torque-producing current command supplied to the stator windings. The corrective current component generates radial electromagnetic forces in the motor air gap that counteract rotor magnetic eccentricity, thereby reducing vibration and bearing load during motor operation without use of auxiliary mechanical actuators or additional electromagnetic hardware."
