Abstract

The invention discloses a three-dimensional magnetic field modular PCB winding device with integrated drive control. The device comprises a plurality of axial magnetic field modular PCB windings, a plurality of radial magnetic field modular PCB windings, a drive control integration module and a module fixing device. A first-side male connector of the radial magnetic field modular PCB winding is connected with a female connector of the axial magnetic field modular PCB winding in an inserted mode, and a second-side male connector of the radial magnetic field modular PCB winding is connected withan integrated female connector in an inserted mode. The plurality of radial magnetic field modular PCB windings form a hollow cylindrical structure, and the plurality of axial magnetic field modularPCB windings are inserted into the plurality of radial magnetic field modular PCB windings in a one-to-one correspondence manner, serve as the top of a hollow cylindrical structure, and are fixed by the module fixing device, thereby improving the power density of the motor. The circuit connection mode on each modular PCB winding is consistent with the formed winding arrangement mode, the consistency of armature motor winding rule arrangement and products is guaranteed, the modules are assembled in an inserting mode, when a certain module breaks down, only the broken-down module needs to be maintained and replaced, the maintenance cost and the maintenance difficulty are reduced, and the maintenance period is shortened.

Description

technical field [0001] The invention relates to the field of motors, in particular to a three-dimensional magnetic field modular PCB winding device with integrated drive control. Background technique [0002] The high-speed flywheel motor plays an important role in the attitude control of the spacecraft. The special working environment of the spacecraft determines its strict requirements on the power density, efficiency, and environmental adaptability of the motor. In high-speed flywheel motors, the stator coreless structure is generally selected to reduce motor loss; in ironless motors, the armature winding is generally in the form of cast motor windings or stator brackets wound on non-magnetic materials such as epoxy resin , but in actual processing, it is difficult to ensure the consistency of the casting winding, which is not conducive to mass production, and the difference in the winding position will affect the performance of the motor.
