MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202527035027 A) filed by Mitsubishi Electric Mobility Corporation, Tokyo, on April 10, for 'motor control device and electric power steering device.'
Inventor(s) include Tokura Yugo; Fujimoto Chiaki; Ishikawa Kosuke; and Matsushita Masaki.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "This motor control device controls energization of a motor through vector control the motor control device comprising: a current command value calculation unit that generates a current command value in a dq coordinate system on the basis of a command value of the motor; a current command value limiting unit that limits the current command value that was generated by the current command value calculation unit in the dq coordinate system and outputs a current limit command value which is the current command value in the dq coordinate system after limiting; and a controller that calculates a voltage command value to the motor though feedback control for the current limit command value the current command value limiting unit limiting the current command value in the dq coordinate system on the basis of a DC bus voltage and the voltage command value so that an operating point has a set voltage margin with respect to a voltage limit circle in the dq coordinate system."
The patent application was internationally filed on Oct. 20, 2022, under International application No.PCT/JP2022/039025.
