Detailed Description

Referring collectively to fig. 1-4, according to an embodiment of the present application, a rotor baffle assembly, comprises:

the baffle body is arranged close to the rotor iron core 3; the baffle body is annular and comprises a tooth part;

the tooth portion is provided with a plurality of first teeth 21, and the first teeth 21 are uniformly distributed on the outer periphery of the baffle body and abut against the rotor teeth 31 slot of the rotor core 3.

Set up first tooth 21 in rotor baffle body periphery, first tooth 21 is direct and 31 groove butts of rotor tooth to realize that the baffle body blocks magnet steel 34 in rotor core 3 and the 31 groove of first tooth 21 rotor tooth, can prevent that rotor core 3 from appearing the phenomenon of fin, guarantee rotor core 3's quality.

To the thin and small iron core of magnetism isolating bridge, easily produce the iron core and warp when adorning magnetism magnet steel 34, lead to the defective rate to increase, adopt above-mentioned rotor baffle subassembly, can keep off the iron core and protect, avoid its deformation.

Before the magnetic steel 34 is installed, the baffle body is in tooth fit with the rotor core 3, the screw rod hole 33 and the screw rod hole 23 are locked by the screw rod 5, so that the rotor core 3 is not warped when the magnetic steel 34 is placed in, and the qualified process quality is ensured; after the magnetic steel 34 is placed in, the position of the baffle body or the iron core is rotated, so that the first teeth 21 are tightly attached to the magnetic steel 34, and the screw rod 5 locks the baffle screw hole 33 and the screw rod hole 23 to prevent the magnetic steel 34 from loosening and prevent the iron core from warping in the operation process.
