Abstract

The invention relates to a mining flameproof threephase asynchronous motor with small volume and large power, in particular to a water cooling structure of a motor. A front end cover and a rear end cover of a motor and a motor base are respectively provided with cooling water channels; the cooling water channels of the front end cover and the rear end cover of the motor and the motor base are connected in series to form a cooling water path. The cooling water channel of the motor base comprises three parts which are respectively sealed, namely the part connected with the cooling water channel of the front end cover, the part connected with the cooling water channel of the rear end cover, and the cooling water channel part of the motor base. The invention has the advantages that as the cooling water channels of the front end cover and the rear end cover of the motor and the motor base are connected in series to form one cooling water path, the cooling structure of the motor and the cooling water supply system of coal mine machinery are simplified; under the situation that the cooling water supply system of coal mine machinery operates normally, the short-term damage to the motor bearing can be effectively avoided.

Description

technical field [0001] The invention relates to a flameproof small-volume high-power three-phase asynchronous motor for mining, in particular to a water-cooled motor structure. Background technique [0002] The driving motor of mechanical equipment in coal mines directly affects the heat dissipation of the motor due to the harsh working environment and poor ventilation. However, the working conditions that require small size, high power and continuous operation of the motor, such as coal shearers, conveyors and roadheaders, all have high requirements on the output of the motor. This kind of working condition directly causes the motor to generate high heat, so the machine base is often used Water-cooled structure. However, due to the complex working conditions in the mine, the explosion-proof three-phase asynchronous motor for mining is a motor with a closed structure, and the internal thermal field belongs to the temperature field of three heat sources, and both the stator ...
