Problems solved by technology

[0005] Second, there will be gaps between the two components of the annular aluminum shell 103 and the silicon steel sheet 104 that are not completely close to each other, resulting in obstacles to heat conduction;
[0006] Its three, existing practice is to make spiral channel 1031 outside annular aluminum shell sheet 103, and annular base 102 is liquid-tightly closed outside the spiral channel 1031 of annular aluminum shell sheet 103, and on annular base 102, make cooling Water circulation port 1021; but the above method consumes a lot of materials and costs, and the annular aluminum shell 103 assembly must be added to form a spiral water channel 1031 between the annular aluminum shell 103 and the annular base 102

Abstract

The invention relates to a cold-liquid and direct-driving motor stator, which comprises a ring base, a silicon steel sheet, at least one cooling metal pipe and a coil. A rotary shaft which a magnet is arranged in the center of the cold-liquid and direct-driving motor stator; a plurality of holding grooves are opened and arranged on the surface of the silicon steel sheet; the cooling metal pipe is arranged in the holding groove of the silicon steel sheet in a bended and extended way and the cooling metal pipe is used for flow of cooling liquid. Therefore, the invention can simplify the parts, directly cool down the silicon sheet, effectively and rapidly reduce the high temperature of the direct-driving motor stator as well as further cooperate with a water channel cold-liquid system of a ring aluminum shell sheet and realize the practicality.

Description

technical field [0001] The invention relates to a direct-drive motor, in particular to a liquid-cooled direct-drive motor stator. The motor stator can directly cool the silicon steel sheet, effectively and quickly reduce the high temperature of the direct-drive motor stator, and is more suitable for the current situation. Some water channel liquid cooling systems on the annular aluminum shell. Background technique [0002] Today's motor devices are more and more used in industry. The main types of devices are outer rotors, inner rotors, etc. In addition to the high-precision effect of feed transmission, they also have low friction loss rate and energy conversion rate. It is self-evident that the importance of motor devices for various industrial application tools is self-evident. [0003] The current direct-drive torque motor device is suitable for high-precision, high-load equipment drives, such as: automation equipment, indexing plates and various machine tools; such as ...
