High-efficiency energy-saving plastic sealing motor and mounting method thereof

Abstract

The invention relates to a high-efficiency energy-saving plastic sealing motor and a mounting method thereof, including a middle plastic sealing body, a rear end cover, fixing ears, a rotating shaft,a rotor and a stator. A rear end cover is arranged at the rear end of the middle plastic sealing body; the middle plastic sealing body and the rear end cover are provided with the fixing ears; the rear end cover is installed on the middle plastic sealing body through fixing bolts; the front end of the middle plastic sealing body is provided with a front end cover; the front end cover is adhesivelyintegrated with the middle plastic sealing body; a through hole is arranged in the middle of the inner side surface of the front end cover, and a front sealing sleeve installed on the outer side of the through hole is arranged on the outer side of the front end cover; and a moisture-proof plate is arranged on the inner side of the front end cover. The plastic sealing motor divides the whole motorinto three parts, wherein the front end cover and the rear end cover are respectively provided with one moisture-proof plate, so that the inside of the plastic sealing motor is always in a dry state,thereby effectively reducing the energy consumption of the motor. The circulation hole in the middle plastic sealing body can circulate and cool the air inside the motor to make the rotor and variouscomponents in the low-temperature working environment, which can reduce the motor's power consumption due to excessive heat production. The low temperature environment is conducive to maintenance ofthe long-term efficient operation of the motor.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving plastic-sealed motor and an installation method thereof, belonging to the field of motors. Background technique [0002] The plastic-encapsulated motor uses plastic packaging technology to package the stator core and winding of the motor with engineering plastics, which can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. This kind of micro motor is used in household appliances such as vacuum cleaners, range hoods, air conditioners, washing machines and instrument fans. At home and abroad, more and more attention is paid to the development and production of plastic-encapsulated motors. It has a bright future because of a series of advantages that metal-cased motors do not have. Specifically, the plastic-encapsulated motor includes a plastic-enclosed stator assembly, a rotor assembly installed inside the plastic-enclosed stator assembly...

AI Technical Summary

Problems solved by technology

Although the plastic-sealed motor has a certain waterproof function, however, the plastic-sealed motor is not completely sealed. During long-term use, moisture will accumulate inside the plastic-sealed motor, which will interfere with the normal operation of the motor and increase the power consumption of the motor.

In addition, since the stator of the plastic-encapsulated motor is wrapped by the casing, and the motor is generally located inside the plastic casing, the heat generated inside the motor cannot be dissipated during the long-term operation of the motor, which will cause the internal components to expand and further increase the distance between the components. The friction between the motors increases the power consumption of the motor

At present, there is no solution to ensure the long-term dry environment inside the plastic-enclosed motor and the low-temperature environment inside the plastic-enclosed motor, and these problems will affect the energy consumption and work efficiency of the plastic powder motor. motor for further research
