Description

Technical Field

[0001] The invention relates to a curved planetary magnetic induction motor, belonging to the technical field of magnetic induction motors. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its principle is to convert electric energy into mechanical energy. The motors in the prior art are large in size, not conducive to installation, and have relatively low power, so they are not suitable for use in many occasions. Permanent magnet motors have the advantages of simple structure, high power density, and efficient operation. They are widely used in electric vehicles, power generation systems, industrial equipment and other fields. However, new application fields such as spacecraft, unmanned aerial vehicles, reaction flywheels of satellites, rockets, and oil pump systems have higher requirements for permanent magnet motors, especially for thin installation, smaller moment of inertia, faster response speed, higher efficiency, lower vibration frequency, and lighter weight of permanent magnet motors. In traditional permanent magnet motors, the armature winding is located in the stator core slot. Due to the slot effect, torque pulsation occurs when the motor rotates, which reduces the dynamic response speed and increases the vibration noise. The motor core is made of high magnetic permeability silicon steel sheets, which can reduce the magnetic resistance of the magnetic circuit, but it accounts for 60% of the total weight of the motor. The core loss of the motor is too large, which restricts the improvement of efficiency. Summary of the invention
