MOTOR CONTROLLER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240322725 titled 'MOTOR CONTROLLER

Simplified Explanation:

This patent application describes a motor controller that includes a power converter and a current command calculator. The power converter supplies alternating current power to each phase of a multiphase motor by converting input power. The current command calculator calculates a current command value for the motor, defined by a current amplitude and phase. It also executes a phase adjustment process to prevent the motor from being energized on the same phase for a predetermined time or longer when the motor is in a locking energization state.

  • The motor controller includes a power converter and a current command calculator.
  • The power converter supplies alternating current power to each phase of a multiphase motor.
  • The current command calculator calculates a current command value for the motor based on current amplitude and phase.
  • It executes a phase adjustment process to prevent the motor from being energized on the same phase for a predetermined time in a locking energization state.

Key Features and Innovation:

  • Power converter supplies alternating current power to multiphase motor.
  • Current command calculator calculates current command value based on amplitude and phase.
  • Phase adjustment process prevents energizing motor on same phase for extended periods.

Potential Applications:

  • Industrial automation
  • Robotics
  • Electric vehicles

Problems Solved:

  • Prevents motor from being energized on the same phase for extended periods.
  • Optimizes motor performance and efficiency.

Benefits:

  • Improved motor performance
  • Enhanced efficiency
  • Extended motor lifespan

Commercial Applications:

Electric Vehicle Motor Controllers: Optimizing motor performance and efficiency in electric vehicles.

Questions about Motor Controller Technology:

1. How does the phase adjustment process in the motor controller prevent energizing the motor on the same phase for a predetermined time?

  The phase adjustment process gradually changes the current phase over time to ensure the motor is not energized on the same phase for a set period.

2. What are the potential industrial applications of this motor controller technology?

  This technology can be applied in industrial automation, robotics, and electric vehicles for improved motor performance and efficiency.


Original Abstract Submitted

a motor controller includes a power converter and a current command calculator. the power converter supplies alternating current power to each phase of a multiphase motor by converting input power. the current command calculator calculates a current command value for a current supplied to the multiphase motor, the current command value being defined by a current amplitude and a current phase, the current command calculator executes a phase adjustment process in a case where the multiphase motor is in locking energization being a state in which the multiphase motor is being energized while the multiphase motor has stopped rotation, except when the multiphase motor satisfies a predetermined exemption condition. the phase adjustment process is a process in which the current phase of the current command value is changed over time to prevent the multiphase motor from being energized on same phase for a predetermined time or longer.
