Abstract

The invention relates to a coreless motor stator glue pouring and shaping mechanism, in particular relates to a permanent magnetic brushless direct-current motor coreless stator glue pouring and shaping mechanism which is suitable for a magnetic suspending flywheel, and belongs to the technical field of spacecrafts. The mechanism disclosed by the invention has the advantages that the structure is compact, the weight is light, the operation is easy, and one-time molding of glue pouring and shaping can be realized; in the mechanism provided by the invention, a lock nut is matched with a base by adopting a T-shaped screw thread, so that self-locking requirements can be met, no springback of a middle coil in the shaping process is ensured, and the shape and dimension of the coil are ensured.

Description

technical field [0001] The invention relates to a glue filling and shaping mechanism for a hollow cup motor stator, in particular to a hollow cup stator glue filling and shaping mechanism for a permanent magnet brushless DC motor used for a magnetic levitation flywheel, and belongs to the technical field of spacecraft. Background technique [0002] Inertial actuators are the core actuators commonly used for attitude control of spacecraft platforms such as satellites and space stations, and maglev flywheels are one of the most important types. The high-speed permanent magnet brushless DC motor provides the angular momentum required for the output torque of the inertial actuator by driving the flywheel to rotate at a high speed, which is one of the key technologies of the maglev flywheel. [0003] The high-speed permanent magnet brushless DC motor adopts a skeletonless hollow cup stator structure, the winding is made into a cup shape, the wires overlap and stagger, the coil re...
