MOTOR DRIVING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17985354 titled 'MOTOR DRIVING APPARATUS
Simplified Explanation
The patent application describes a motor driving apparatus that includes a motor with windings for multiple phases, two inverters, and a controller.
- The first inverter provides an AC voltage to one end of the windings based on the phases.
- The second inverter provides an AC voltage to the other end of the windings based on information from the changeover switch.
- The controller controls the changeover switch based on the motor driving mode.
- The changeover terminals of the second power modules are short-circuited to each other.
Potential applications of this technology:
- Electric vehicles: This motor driving apparatus can be used in electric vehicles to efficiently control the motor and optimize power distribution.
- Industrial machinery: The apparatus can be applied in various industrial machinery to enhance motor performance and control.
- Renewable energy systems: It can be utilized in renewable energy systems, such as wind turbines or solar power systems, to improve motor efficiency and power management.
Problems solved by this technology:
- Efficient motor control: The apparatus allows for precise control of the motor by providing AC voltage to different windings based on the motor driving mode.
- Power optimization: By short-circuiting the changeover terminals, the apparatus ensures efficient power distribution and reduces energy loss.
- Simplified design: The use of two inverters and a controller simplifies the motor driving system, making it more compact and cost-effective.
Benefits of this technology:
- Improved motor performance: The precise control and optimized power distribution result in enhanced motor performance, including higher efficiency and smoother operation.
- Energy efficiency: The apparatus reduces energy loss through short-circuiting the changeover terminals, leading to improved overall energy efficiency.
- Cost-effectiveness: The simplified design and efficient power management contribute to a more cost-effective motor driving system.
