Research on bearing characteristics of air gap flow-field for a maglev spherical motor

In this article, the air gap flow-field for a maglev spherical motor is investigated. First, the formation mechanism for a maglev spherical motor rotating along an arbitrary axis in the three-dimensional rotating magnetic field is analyzed, and the structure of the maglev spherical motor is designed. Then, the static and dynamic characteristics of the motor are investigated by studying the air gap flow-field of the maglev spherical motor in terms of the aerodynamics. The mathematical models of the static and dynamic pressure and kinetic parameters for the air gap flow field are established. Finally, the experiment study is made to confirm the influence on the static bearing capacity and dynamic characteristics of the motor, which is generated by the air gap flow-field of the maglev spherical motor.
