MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202527066596 A) filed by Mitsubishi Electric Corporation, Tokyo, on July 11, for 'control device for rotary machine.'
Inventor(s) include Furukawa Akira; and Kondo Shota.
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: "A control device for a rotary machine comprises: a current command generation unit; a field winding voltage command unit; and a stator winding voltage command unit. The current command generation unit (81) includes: a current command calculation unit (810) that calculates a field winding current command and a stator winding current command on the basis of an operation command and a DC voltage; an allowable flux calculation unit (811) that calculates an allowable flux interlinking with a stator winding, the allowable flux being calculated on the basis of the rotation speed, the DC voltage, the stator winding current command, and the field winding current; a first flux-weakening current calculation unit (812) that calculates a first flux-weakening current on the basis of the field winding current, the stator winding current command, and the allowable flux; and a final current command calculation unit (813) that calculates a final stator winding current command on the basis of the stator winding current command and the first flux-weakening current."
The patent application was internationally filed on Mar. 17, 2023, under International application No.PCT/JP2023/010534.
