This abstract first appeared for US patent application 17743163 titled 'APPARATUS FOR SUPPRESSING TORQUE GENERATION OF THREE-PHASE MOTOR AND METHOD THEREOF

==Simplified Explanation==

The patent application describes an apparatus and method for suppressing torque generation in a three-phase motor. Here is a simplified explanation of the abstract:

* The invention aims to suppress torque generated by a zero phase sequence component current in a three-phase motor.
* A torque determination device calculates a second torque value to counteract the first torque value caused by the zero phase sequence component current.
* A control amount determination device determines the voltage control amount needed to generate the calculated second torque value.
* A controller is responsible for controlling the three-phase motor based on the determined voltage control amount.

Potential applications of this technology:

* Industrial machinery: This invention can be applied to various types of industrial machinery that utilize three-phase motors, such as pumps, compressors, and conveyors.
* Electric vehicles: The technology can be used in electric vehicles to improve motor performance and efficiency.
* Robotics: It can be implemented in robotic systems that rely on three-phase motors for movement and operation.

Problems solved by this technology:

* Torque suppression: The invention addresses the issue of torque generated by the zero phase sequence component current, which can cause instability and inefficiency in three-phase motors.
* Motor control precision: By accurately determining the voltage control amount, the technology ensures precise control of the motor's torque output.
* Improved motor performance: Suppressing unwanted torque allows for smoother motor operation, reduced vibrations, and improved overall performance.

Benefits of this technology:

* Enhanced motor efficiency: By suppressing torque generated by the zero phase sequence component current, the invention helps optimize motor efficiency and reduce energy consumption.
* Increased motor lifespan: The technology minimizes stress and strain on the motor, potentially extending its lifespan.
* Improved system stability: By controlling torque generation, the invention contributes to the stability and reliability of systems utilizing three-phase motors.
