MOTOR DRIVING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17840776 titled 'MOTOR DRIVING APPARATUS
Simplified Explanation
The abstract describes a motor driving apparatus that controls a motor with multiple windings and phases using two inverters and a controller. The controller uses pulse width modulation to distribute a preset voltage command to the first and second inverters and generates duties for the switching elements in the first inverter. The controller also determines the duties for the switching elements in the second inverter.
- The motor driving apparatus controls a motor with multiple windings and phases.
- It includes a first inverter connected to one end of each winding and a second inverter connected to the other end of each winding.
- A controller is used to control pulse width modulation and distribute the voltage command to the first and second inverters.
- The controller generates duties for the switching elements in the first inverter and determines the duties for the switching elements in the second inverter.
Potential applications of this technology:
- Electric vehicles: The motor driving apparatus can be used in electric vehicles to control the motor and improve efficiency.
- Industrial machinery: This technology can be applied to various industrial machinery that requires precise motor control.
- Robotics: The motor driving apparatus can be used in robotic systems to control the movement and operation of robotic arms or other components.
Problems solved by this technology:
- Efficient motor control: The motor driving apparatus optimizes the distribution of voltage commands and duties to improve the overall efficiency of the motor.
- Precise control: The controller determines the duties for the switching elements in both inverters, allowing for precise control of the motor's operation.
- Simplified design: The use of two inverters and a controller simplifies the motor driving apparatus design compared to traditional methods.
Benefits of this technology:
- Improved efficiency: By optimizing voltage distribution and duties, the motor driving apparatus can improve the efficiency of the motor, leading to energy savings.
- Enhanced control: The precise control provided by the controller allows for better performance and responsiveness of the motor.
- Simplified implementation: The use of two inverters and a controller simplifies the design and implementation of the motor driving apparatus, making it easier to integrate into various systems.
