LINEAR MOTOR, TRANSPORT APPARATUS, AND PRODUCTION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18496000 titled 'LINEAR MOTOR, TRANSPORT APPARATUS, AND PRODUCTION APPARATUS
Simplified Explanation
The disclosed linear motor includes a stator with cores and coils, and a movable element with a permanent magnet, driven by electromagnetic force from the stator. Each core has an excitation unit wound with a coil and an acting unit magnetically coupled to the excitation unit, working on the permanent magnet of the movable element. The motor includes an airgap or heat conduction reduction portion between the excitation unit and the acting unit, reducing heat conduction compared to direct contact.
- Stator with cores and coils
- Movable element with permanent magnet
- Electromagnetic force as driving force
- Cores have excitation and acting units
- Airgap or heat conduction reduction portion
- Reduces heat conduction between units
- Potential Applications
- Industrial automation systems - Robotics - Linear actuators - CNC machines
- Problems Solved
- Heat generation in linear motors - Efficiency loss due to heat conduction - Wear and tear on motor components
- Benefits
- Improved efficiency - Longer lifespan of motor - Reduced maintenance needs
Original Abstract Submitted
The disclosed linear motor includes a stator having a plurality of cores and coils that excite the plurality of cores, respectively, and a movable element having a permanent magnet and configured to move using electromagnetic force applied from the stator as driving force, each of the plurality of cores has an excitation unit wound with the coil and an acting unit configured to be magnetically coupled to the excitation unit and cause a magnetic flux applied from the excitation unit to work on the permanent magnet of the movable element, and the linear motor includes an airgap or a heat conduction reduction portion between the excitation unit and the acting unit, and the heat conduction reduction portion reduces heat conduction from the excitation unit to the acting unit more than in a case where the excitation unit and the acting unit are in direct contact with each other.
