Abstract

The invention is longevous fan and the manufacturing method. It refers to single-phase alternating claw pole magneto synchronous electrical machine, especially refers to the fan with electrical machinery made up by in field armature and magneto out rotator. It includes up and down end cap, armatures, magnetism slices, starting box and flying rings. The armature comprises iron core, coils, up and down claw pole. The wire frame ion core is made up of iron core, part made up of up and down end boards, cross section of iron core and coils aren't rounded, the wire frame iron core, up and down end board are made up from magnetism materials. The up and down end boards are welded or rivet jointed on iron core, the up and down claws are fixed on up and down end boards.

Description

technical field [0001] The invention relates to a single-phase AC claw-pole permanent magnet synchronous motor fan, in particular to an electric fan composed of an inner excitation armature and a permanent magnet outer rotor motor. Background technique [0002] Existing electric fan with internal excitation armature and permanent magnet outer rotor motor, its internal excitation armature is made up of coil, upper and lower claw poles, iron core, bearing screw, pressure plate and main shaft. Each part is fastened on the main shaft by bearing screws. Because there are many parts, the diameter of the armature is large, the torque is large, and the bearing screw cannot be too large, so the fastening force cannot be large. When the fan is running, there will be looseness between the parts, which will shorten the life of the fan. Secondly, the coil frame is made of non-metallic material, the winding place is thin-walled, and the coil is round after win...
