Abstract

The invention provides a rotor profile type and magnetic field coupling based electric and permanent magnet rotor system design method. The rotor profile type and magnetic field coupling based electric and permanent magnet rotor system design method comprises the following steps of step 1, the rotor profile design; step 2, the magnetic field coupling rapid algorithm; step 3, the control method design of a driving mechanism. The rotor profile type and magnetic field coupling based electric and permanent magnet rotor system design method is a complete design scheme for an electric and permanent magnet rotor direct driving system, the initial rotor profile extends to the magnetic field calculation, and the feasible method for controlling the driving system is provided finally. According to the driving system design achieved by the rotor profile type and magnetic field coupling based electric and permanent magnet rotor system design method, the displacement, speed and acceleration output of the system can be directly determined through the control of the current and the annular current coil based permanent magnet magnetic field calculation mode is provided for the electromagnetism calculation and accordingly the multivariate solving can be rapidly performed in comparison with other electromagnetism commercial calculator software and the invested time cost required by the early design is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of auxiliary design process of an electromagnetic-permanent magnet coupling drive system, in particular to an electro-permanent magnet rotor system design method based on rotor profile and magnetic field coupling. Background technique [0002] In the electric-permanent magnetic coupling direct drive, the profile of the permanent magnet rotor directly affects the output performance of the drive, so it is necessary to develop a set of procedures for designing the rotor profile to meet the specific output requirements of the drive. In addition, since the rotor is driven by the coupling of the permanent magnet magnetic field and the external electromagnetic field to generate torque, the result of the magnetic field coupling must be calculated. However, the calculation results cannot be quickly obtained by using general commercial large-scale electromagnetic calculation software, and the long solution tim...
