Remote air-taking air-cooled motor

Abstract

The invention relates to a remote air-taking air-cooled motor, which comprises a motor shell, a front end cover and a rear end cover, wherein the front end cover is provided with a cooling medium input cavity and a cooling medium input interface, the rear end cover is internally provided with a cooling medium output cavity, and the cooling medium output cavity is provided with a plurality of air outlet holes penetrating through the end face of the end, away from the motor shell, of the rear end cover. The motor rotating shaft is connected with an air draft blade which drives air in the coolingmedium output cavity to flow out through the air outlet hole when the motor rotating shaft rotates, the rear end cover is connected with a protective cover which covers the air draft blade and is provided with a ventilation hole, and a plurality of cooling medium channels which are communicated with the cooling medium input cavity and the cooling medium output cavity are arranged in the motor shell. And the cooling medium input interface is connected with an airflow leading-in pipe through an air conveying pipe. The invention provides a remote air-taking air-cooled motor, which solves the problem that the heat dissipation effect is poor when the temperature of the environment where a motor is located is high due to the fact that a heat dissipation fan is installed on a rotating shaft of the motor for heat dissipation in the prior art.

Description

technical field [0001] The invention relates to a motor, in particular to an air-cooled motor with air taken from a different place. Background technique [0002] Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. [0003] The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function The function is to convert mechanical energy into electrical energy. The basic structure of the motor includes a motor casing, a stator fixed in the motor casing, a rotor pierced in the stator, and a motor shaft connected to the rotor. One end of the casing is provided with a front end cover, the other end is provided with a re...
