Problems solved by technology

Although they are all software specifically for motor-aided design, the analysis results obtained by using these aided design software are given in the form of two-dimensional graphics and charts, so their intuition and interaction are limited, and they cannot be pre-assessed. Dynamic simulation of the operation of the motor when driving the load; the performance of the auxiliary design motor cannot be effectively evaluated, which is not conducive to the improvement of the motor design, prolongs the time of motor design, and increases the cost of motor design

Abstract

The invention relates to a three-dimensional virtual brushless DC motor dynamic simulation method, belonging to the technical field of computer aided design (CAD). The method comprises the following steps: a, establishing a mechanism model for a brushless DC motor; b, establishing a three-dimensional virtual reality scene model for the brushless DC motor, i.e. establishing the three-dimensional model of each part and load of the brushless DC motor, and converting the three-dimensional models into 3ds files and outputting the 3ds files; c, realizing the virtual reality scene; and d, realizing the interaction of virtual simulated programs. When the three-dimensional brushless DC motor of the invention carries out an interaction operation, the visualization is good; and when the brushless DC motor carries out the interaction, the invention can lead the motor design to reach the optimum performance by amending the motor design and operating parameters in the interaction process, and can be used for testing the design performance of the brushless DC motor in advance.
