MOTOR CONTROLLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18678862 titled 'MOTOR CONTROLLER
Simplified Explanation:
The 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, while the current command calculator calculates a current command value for the motor.
Key Features and Innovation:
- Power converter supplies alternating current power to each phase of a multiphase motor.
- Current command calculator calculates a current command value for the motor.
- Phase adjustment process prevents the motor from being energized on the same phase for a predetermined time or longer.
Potential Applications: The technology can be used in various industrial applications where precise control of multiphase motors is required, such as in manufacturing, robotics, and automation.
Problems Solved: The technology addresses the issue of locking energization in multiphase motors, where the motor is energized while not rotating, by implementing a phase adjustment process to prevent damage.
Benefits:
- Improved efficiency and control of multiphase motors.
- Prevents damage to the motor due to locking energization.
- Enhances the overall performance and longevity of the motor.
Commercial Applications: The technology can be applied in industries that rely on multiphase motors for their operations, such as automotive, aerospace, and renewable energy sectors.
Prior Art: Readers can start their search for prior art related to this technology by looking into patents or research papers on motor control systems, multiphase motor technology, and power converters.
Frequently Updated Research: Researchers are constantly exploring new ways to optimize motor control systems for improved efficiency and performance. Stay updated on the latest advancements in the field to leverage the full potential of this technology.
Questions about Motor Controller Technology: 1. What are the key components of a motor controller system? 2. How does the phase adjustment process in the current command calculator prevent locking energization in multiphase motors?
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.
