The invention discloses an integrated PCB winding disc motor system. The integrated PCB winding disc motor system consists of an upper rotor disc, a lower rotor disc and a stator disc to form a bilateral permanent magnet disc motor structure, which can overcome unilateral magnetic pull, reduce magnetic flux leakage, and make full use of permanent magnet materials, which is beneficial to Improve the performance of the motor, reduce the cost, reduce the volume, and the axial dimension is short, the structure is compact, and it is suitable for occasions where the space is strictly required. In the disc motor system of the present invention, the stator and the rotor are equally arranged, the heat dissipation is good, and higher power density can be obtained. In addition, the adjustable mechanism added on the rotating shaft can not only realize the adjustable upper and lower air gaps of the motor, but also facilitate the expansion and adjustment of the layers of the integrated PCB winding structure, so that the performance of the motor can be optimized.
Description
technical field [0001] The invention relates to the technical field of disc motors, in particular to an integrated PCB winding disc motor system. Background technique [0002] The aerospace industry plays an irreplaceable role in national defense construction and national production. In recent years, with the development of micro and small spacecraft such as micro-nano satellites, pico satellites, and agile small The demand for miniaturized actuators is becoming more and more urgent. As the core component of the attitude control flywheel system, the performance of the motor directly affects the accuracy, response speed and stability of the attitude control flywheel system. The special working environment of the spacecraft determines that it has strict requirements on the power density, efficiency, and environmental adaptability of the motor. [0003] Compared with some weaknesses of ordinary cylindrical motors, such as low rotor core utilization and difficult cooling, the a...
