Description
Technical Field
The utility model belongs to the technical field of the technique and specifically relates to a motor stator base structure for unmanned aerial vehicle.
Background
The stator is a fixed part of the machine and consists of a stator core, a stator winding and a base. The stator mainly acts on generating a rotating magnetic field, and the rotor mainly acts on being cut by magnetic lines of force in the rotating magnetic field to generate (output) current; the stator base determines the quality of the stator winding to a large extent; the structural quality of which is therefore very demanding.
The existing stator base has some problems, for example, after the existing stator base is used for a long time, the base and the rotating shaft can slide relatively, so that the phenomena of rotating shaft abrasion and motor damage are caused.
