THERMAL CONNECTION SYSTEM FOR A STATOR CORE OF AN AXIAL FLUX ELECTRIC MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240014699 titled 'THERMAL CONNECTION SYSTEM FOR A STATOR CORE OF AN AXIAL FLUX ELECTRIC MOTOR
Simplified Explanation
The abstract describes an axial flux electric motor that includes a housing, a stator, and a thermal connection system. The stator is fixedly mounted in the housing and consists of multiple stator segments, each supporting a winding. The stator also includes an inner support member with a central passage and an outer annular member that constrains the stator segments. The outer annular member has an outer surface portion that abuts the inner surface of the housing. The thermal connection system is placed between the outer surface portion of the outer annular member and the inner surface of the housing to transfer heat from the stator into the housing.
- The motor has an axial flux design, meaning the magnetic field is oriented parallel to the rotor shaft.
- The stator is divided into segments, each supporting a winding, allowing for better control and efficiency.
- The inner support member and outer annular member provide structural support and constraint for the stator segments.
- The thermal connection system ensures efficient heat transfer from the stator to the housing, preventing overheating.
Potential Applications
- Electric vehicles: The axial flux motor design can be used in electric vehicles to provide efficient and compact propulsion.
- Industrial machinery: The motor can be used in various industrial applications that require high torque and power output.
- Renewable energy systems: The motor can be utilized in wind turbines or hydroelectric generators to convert mechanical energy into electrical energy.
Problems Solved
- Overheating: The thermal connection system helps dissipate heat generated by the stator, preventing damage to the motor.
- Efficiency: The axial flux design and segmented stator allow for better control and utilization of magnetic fields, improving overall motor efficiency.
- Compactness: The design of the motor allows for a more compact and lightweight construction, making it suitable for various applications with limited space.
Benefits
- Improved efficiency: The motor design and thermal connection system help reduce energy losses and improve overall efficiency.
- Compact and lightweight: The axial flux design and segmented stator contribute to a more compact and lightweight motor, making it easier to integrate into different systems.
- Enhanced reliability: The thermal connection system helps dissipate heat, reducing the risk of overheating and improving the motor's reliability and lifespan.
