Abstract

The invention discloses an inner rotor motor for a fan. The inner rotor motor comprises a cast iron shell (1), a plastic housing (2), a revolving shaft (3) and a water-proof cover (5), wherein the end part of the revolving shaft (3) extends out of the plastic housing (2); a threaded connecting rod (4) is arranged on the end part of the revolving shaft (3); the water-proof cover (5) covers the end part of the revolving shaft (3); a first vibration isolation pad (6) sleeves the threaded connecting rod (4); a plurality of elastic columns (10) which are uniformly distributed in the circumferential direction are arranged on the upper surface of the first vibration isolation pad (6); and a first water guide groove (12) and a plurality of second water guide groove (11) which are distributed radially are formed in the outer surface of the water-proof cover (5). The inner rotor motor is suitable for a use environment with a high waterproofing grade requirement, and the performance of the inner rotor motor for the fan in the use environment with the high waterproofing grade requirement is ensured.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an inner rotor motor for a fan. Background technique [0002] At present, there is an inner rotor motor for a fan, which includes a cast iron shell, a plastic cover and a rotating shaft. The cast iron shell and the plastic cover are assembled together along the axial direction of the rotating shaft. The plastic cover is provided with a through hole for the end of the rotating shaft to extend out. The end is provided with a threaded connecting rod for connecting the wind wheel, and the threaded connecting rod is used to axially lock the wind wheel. Since the above structure can only reach the IPx4 waterproof level, it is not suitable for the use environment that requires a higher waterproof level. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an inner rotor motor for a fan that is suitable for use in an environment requ...
