PERMANENT MAGNET SYNCHRONOUS MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022125 titled 'PERMANENT MAGNET SYNCHRONOUS MOTOR
Simplified Explanation
The abstract describes a permanent magnet with a recessed portion that fits into a rotor core. The distance between the recessed portion and the outer periphery's circular arc portion of the magnet is defined as "l". The magnet includes a recessed portion that satisfies a condition called "ll".
- The permanent magnet has a recessed portion that fits into a rotor core.
- The distance between the recessed portion and the outer periphery's circular arc portion is defined as "l".
- The magnet satisfies a condition called "ll".
Potential Applications:
- Electric motors
- Generators
- Magnetic levitation systems
- Magnetic resonance imaging (MRI) machines
Problems Solved:
- Improved magnetic coupling between the magnet and the rotor core
- Enhanced stability and performance of the magnet in various applications
Benefits:
- Increased efficiency and power output of electric motors and generators
- Improved precision and stability in magnetic levitation systems
- Enhanced image quality and accuracy in MRI machines
Original Abstract Submitted
a permanent magnet includes a recessed portion to fit therein with a protrusion provide in a rotor core; and, when the shortest distance between outmost part of the recessed portion and an outer periphery's circular arc portion of the magnet is defined as l and when the distance between the recessed portion and the outer periphery's circular arc portion is defined as l where the distance l passes through an intersection point at which a tangential line of outmost part on the recessed portion intersects with a parallel line, which defines as its start point a point from which a changeover to the recessed portion occurs from an adhesion surface between the magnet and the rotor core, and which is in parallel with a radial line extending from the rotor's shaft center toward the center of the magnet, the magnet includes the recessed portion that satisfies ll
