Research On Dual-rotor Permanent Magnet Motor

According to traditional design methods and principles of the motor, the main structural parameters were designed and calculated according to the parameters established structure design model of the motor. Unlike ordinary dual-rotor motor is a permanent magnet synchronous motor, the magnetic field of the permanent magnet motor is generated inside and outside the two will interfere with each other. Because of the special nature of the motor, the stator core and the air gap structure is fully utilized, by changing the size of the inside and outside of the air gap, changing the thickness of the stator yoke section thickness or permanent magnets can be reduced flux coupling relationship between inside and outside, to improve motor output torque and power density, energy saving purposes. Derived in the motor air gap and an outer air gap motor apparatus formula magnetic flux density, the necessity of decoupling the magnetic field.This paper introduces its dual-rotor permanent magnet motor structure, electrical equipment magnetic circuit, principle of operation, electromagnetic inductance path and other operational parameters and the basic understanding and discussion. Materials for different regions, the characteristics of dual-rotor permanent magnet motor research. Permanent magnets research is essential, equally as important is its electromagnetic design, combined with ANSYS finite element simulation software, analyzed and motor magnetic flux density analysis, tests confirmed the results of the design. Structure is designed to achieve the motor, reducing energy consumption and optimize the performance of the motor, there is a wide range of applications.
