Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Examples

Referring to fig. 1 to 4, the plastic-iron integrated external rotor motor provided in the present embodiment includes a motor body 1, a motor base 2 is installed at the bottom of the motor body 1, and a plurality of mounting holes 3 are respectively formed on the left side and the right side of the motor base 2;

a plastic package shell 5 is sleeved on the outer side of the motor body 1, a motor shaft 4 is arranged in the middle of the upper end of the motor body 1, and one end of the motor shaft 4 penetrates through the plastic package shell 5 and is located on the outer side of the plastic package shell 5;

the plastic package shell 5 comprises a plastic shell 51, a mounting groove 52 and a magnetic conductive ring 53, wherein the mounting groove 52 is formed in the inner side wall of the plastic shell 51, the magnetic conductive ring 53 is embedded in the mounting groove 52, the plastic shell 51 is made of BMC materials, and the magnetic conductive ring 53 is made of iron materials.

The utility model discloses in adopt the replacement of plastic envelope shell 5 with the iron shell on the traditional external rotor electric machine, owing to there is magnetic conduction circle 53's effect in the plastic envelope shell 5, it can not cause the influence to the normal use of motor, because the plastic casing 51 of replacement for adopting BMC material from the metal casing, but greatly reduced cost, moreover, the external rotor is more difficult to rust and corrode and pleasing to the eye before comparing, and, after using the plastic casing 51 of BMC material, external rotor and motor shaft 4 become from the metal riveting connection to be connected with the riveting of plastic casing 51, simple process and intensity are high.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present disclosure.
