Alternating current servo motor

Abstract

The invention relates to the technical field of motor manufacturing, and discloses an alternating current servo motor which comprises a motor, a fixing support is fixedly connected to the tail of the motor, an explosion-proof box is fixedly connected to the end, away from the motor, of the fixing support, and connecting plates are fixedly connected to the outer side of a rotating shaft of the motor in the circumferential direction at equal angles. The outer side of the connecting plate is fixedly connected with air outlet boxes located at the top end and the bottom end of the motor, and the inner sides of the ends, away from the connecting plate, of the air outlet boxes fixedly communicate with sleeves. The sleeve is arranged on the tail portion of the motor, electric sparks generated by work of the motor can enable gas in the motor to be heated and expanded, the gas generated by expansion of the motor can be released from the tail portion of the motor, rotation of the supporting plate is stopped, and meanwhile expansion airflow on the inner side of the motor can extrude the air bag. The air inside the air bag pushes the sealing plate to close all the through holes through the communicating pipe, so that the explosion-proof box is sealed relative to the outer side, the motor is isolated from the outside environment, and electric sparks are prevented from being in contact with explosive substances in the environment.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an AC servo motor. Background technique [0002] The AC motor is a machine used to realize the mutual conversion of mechanical energy and AC power. The AC motor is composed of electronics, rotors, bearings, end covers and tail fans. Simple, easy to manufacture and relatively firm. [0003] When the AC motor is working, the electric spark or arc generated by the motor generates a lot of heat instantly, which makes the air inside the motor heat and expand instantaneously, causing the combustion of surrounding substances and other explosive substances, and the fire source that constitutes a fire or explosion will cause the motor to be damaged. In the limited space of the environment, an explosion will occur, causing a safety accident; and when the AC motor is used, a large amount of heat will be generated, and the air flow will be dissipated through the water cooling an...
