Abstract

The invention discloses an integrated PCB winding disc type motor system. According to the integrated PCB winding disc type motor system, the upper rotor disc, the lower rotor disc and the stator discform a double-side permanent magnet disc type motor structure, single-side magnetic pull force can be overcome, magnetic flux leakage is reduced, permanent magnet materials are fully utilized, the motor performance is improved, the cost is reduced, the size is reduced, the axial size is short, and the structure is compact; and the system is suitable for occasions with strict requirements on placement space. According to the disc type motor system, the stator and the rotor are arranged in a peer-to-peer mode, heat dissipation is good, and high power density can be obtained. In addition, the adjustable mechanism additionally arranged on the rotating shaft can realize the adjustability of the upper and lower air gaps of the motor, and can facilitate the expansion and adjustment of the numberof layers of the integrated PCB winding structure, so that the performance of the motor is optimal.

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...
