APPARATUS FOR SUPPRESSING TORQUE GENERATION OF THREE-PHASE MOTOR AND METHOD THEREOF - A simplified explanation of the abstract
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 required 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 innovation can be applied to various types of industrial machinery that utilize three-phase motors, such as pumps, compressors, and conveyor systems.
- Electric vehicles: The technology can be used in electric vehicles to improve motor control and efficiency, leading to better performance and longer battery life.
- HVAC systems: Heating, ventilation, and air conditioning systems often rely on three-phase motors. Implementing this technology can enhance the control and energy efficiency of these systems.
Problems solved by this technology:
- Torque suppression: The invention addresses the issue of torque generation caused by zero phase sequence component currents, which can lead to motor instability and inefficiency.
- Motor control accuracy: By accurately determining the voltage control amount needed to counteract the torque, the technology improves the precision and stability of motor control.
- Energy efficiency: Suppressing unnecessary torque generation helps optimize motor performance, leading to improved energy efficiency and reduced power consumption.
