[ background of the invention ]
In recent years, a large number of air coolers are on the market, and the air coolers have the advantages of low price and low operation cost, so the air coolers are widely used in catering industry, production workshops and other occasions, partially replace refrigeration air conditioners and are very popular in middle east regions with dry climate.
The air cooler is usually internally provided with a water tank, a water pump and a water curtain, the motor is installed on a fan shell and is in transmission connection with the fan, and a user does not feel dry due to air supply and accompanying water vapor.
The existing fan motor for the air cooler has the defects that the rotor is pressed in a center hole of the stator, the two ends of the stator are provided with end covers, and the end covers need to be fixed on a fan shell of the air cooler through special clamping and fixing pieces, so that the existing fan motor for the air cooler has the defect of inconvenient installation.
[ Utility model ] content
The utility model aims at providing a special fan motor of difficult rusty air-cooler to the not enough of its metal casing of traditional motor easy rusty when humid environment moves, and this fan motor simple to operate.
Therefore, the utility model provides a following technical scheme:
the utility model provides a special fan motor of air-cooler, includes motor body, and its improvement point is that the periphery cladding at motor body is fixed with the plastic-sealed body, personally submits central symmetry in the outside of this plastic-sealed body and is equipped with four installation feet, first mounting hole is seted up respectively to four installation feet, the hole center of first mounting hole is located the center that uses motor body as the centre of a circle, the radius is 55 ~ 57 mm's circle.
In order to enhance the universality of the special fan motor during installation, the four installation pins are respectively provided with a second installation hole, and the hole centers of the second installation holes are positioned on a circle which takes the center of the motor main body as the center of circle and has the radius of 65-68 mm.
The four mounting feet and the plastic package body are integrally formed.
For the joint strength of reinforcing installation foot, improve this special fan motor fixed reliability, above-mentioned four installation feet still respectively integrated into one piece have the strengthening rib, set up behind the strengthening rib, special fan motor's operating stability is good.
The utility model has the advantages of as follows with positive effect:
the metal shell of the existing air cooler fan motor is abandoned, the motor main body is wrapped by the plastic package body instead, the motor main body is prevented from contacting with moisture in the running environment where the motor main body is located, the stator and the rotor are not easy to rust, and the insulation performance of the motor main body is improved, so that the fan motor has the advantages of waterproof, corrosion-resistant, moisture-resistant and high-temperature-resistant working conditions, is suitable for being used in a humid environment, effectively protects the parts and components in the motor main body, is not easy to corrode even if the fan motor works in the humid environment for a long time, and prolongs the service life of the motor main body;
the mounting feet located on the outer side face of the motor main body are provided with the first mounting holes, the four first mounting holes are reasonable in position and hole spacing design size, the mounting requirements of the air cooler are met, the mounting is efficient, the requirements of batch and quick installation of engineering are met completely, the air cooler motor in the prior art can be replaced in batch, and the defect that end covers on two sides of the existing motor need to be fixed in a special clamping and fixing mode due to low efficiency is overcome.
