轮缘驱动式姿控飞轮电机设计
Design of rim-driven attitude control flywheel motor
摘要
Abstract
To improve the inertia / mass ratio of attitude control flywheel used in small satellite and lighten the weight of flywheel attitude adjustment system,a brushless DC motor used in flywheel was designed. According to the motor magnetic circuit,the corresponding relationship between the size and maximum energy of magnet was derived. The influence of magnetic circuit parameters on the flywheel performance was analyzed by using the Finite Element Method (FEM). For the flywheel structure feature of large equivalent air-gap and large ratio of diameter to length, a method for calculating air-gap magnetic flux density was proposed. The relationship between winding parameters and the motor rated data was established. Simulation method was used to analyze the motor performances. Compared with a flywheel motor with the angular moment of 5 Nms at the highest speed of 6 000 r/min,the maximum error is 6. 5% .which proves the correctness of the design method.关键词
