MOTOR CONTROL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240283381 titled 'MOTOR CONTROL DEVICE

The motor control device described in the patent application includes various units such as an inverter, current command generation unit, correction value generation unit, voltage command generation unit, dq inverse transform unit, and drive signal generation unit.

  • The inverter generates a three-phase alternating current to drive the motor.
  • The current command generation unit produces d-axis and q-axis current command values.
  • The correction value generation unit generates d-axis and q-axis correction values to suppress noise.
  • The voltage command generation unit generates d-axis and q-axis voltage command values.
  • The dq inverse transform unit converts these values into three-phase voltage command values.
  • The drive signal generation unit creates a drive signal for the inverter.

Potential Applications: - Industrial automation - Electric vehicles - Robotics

Problems Solved: - Efficient motor control - Noise suppression - Improved performance

Benefits: - Enhanced motor efficiency - Reduced noise interference - Precise control over motor operation

Commercial Applications: Title: "Advanced Motor Control Technology for Industrial Automation" This technology can be used in various industries such as manufacturing, automotive, and robotics for precise motor control and improved performance.

Questions about the technology: 1. How does the correction value generation unit suppress noise in the motor control system? 

  The correction value generation unit generates d-axis and q-axis correction values that effectively suppress sixth-order noise in the system.

2. What are the potential implications of using this motor control technology in electric vehicles? 

  The technology can lead to improved efficiency and performance in electric vehicles, making them more competitive in the market.
