Simulation and optimization on the Design of an Airborne Brushless DC Motor

An Output of 7W and rotating speed of1 560 r/min airborne brushless DC motor was designed and optimized by means of the combined magnetic field-circuit method. The fundamental design was done by using the equivalent magnetic circuit while simulations on the static magnetic circuit, performance under no-load or full-load were completed by means of the finite element method. The prototype was manufactured which was used to verify the performance. The result shows that the motor satisfies such requirement of an airborne motor as the dimension, rotating speed and current. The tested counter electromotive force was very close to the simulated value by the finite element method.
