MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517092545 A) filed by Fujitsu General Limited, Kanagawa, Japan, on Sept. 26, for 'motor control device.'
Inventor(s) include Urayama, Masaharu.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "A motor control device (100a) has: a synchronous operation mode in which a motor M is controlled such that the rotational speed of the motor coincides with a speed command value to cause the motor to be synchronized with a rotational phase obtained by integrating the speed command value; and a position sensorless control mode in which the motor M is controlled such that a speed estimation value, obtained by feedback-controlling the axial error between a control system coordinate axis and a rotor coordinate axis, coincides with the speed command value. In the motor control device: a synchronous operation current command value generator (13) generates a current command value in the synchronous operation mode; a current controller (20), a non-interference controller (36), and an adder (21) generate a voltage command value such that a current flowing through the motor M coincides with the current command value; and a lock determination instrument (52) determines whether or not the motor M is locked on the basis of the voltage command value."
The patent application was internationally filed on Mar. 27, 2024, under International application No.PCT/JP2024/012206.
