Abstract

The invention discloses a cooling system of a stator wrap of a motorized spindle and a motorized spindle, a heat dissipation tube is wound on the outer side of the stator wrap, the heat dissipation tube is communicated with a cooling medium passage arranged in the axial direction on the motor housing, and the cooling medium flows into the cooling medium passage and the heat dissipation tube through a cooling medium inlet on the outer side of the motor, and is refluxed to the outer side of the motor through the cooling medium outlet. According to the technical proposal of the invention. The cooling medium can be directly heat exchanged with the motor stator wrap through the heat dissipation tube wound on the motor stator wrap, and the heat exchange efficiency is high, the quick cooling of the motor stator wrap of the motor spindle is realized, the thermal deformation caused by the temperature inability to diffuse is avoided, the motor spindle can be processed with high precision and theservice life of the motor spindle can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and in particular relates to a stator coil cooling system of an electric spindle and an electric spindle adopting the stator coil cooling system. Background technique [0002] The electric spindle has the advantages of compact structure, light weight, small inertia, small vibration, low noise, fast response, etc., and has been widely used in modern manufacturing industries. However, since the stator and rotor of the high-speed electric spindle are all built-in, all of which are in a closed space, the heat generated during high-speed operation is very large, especially at the wire wrap of the motor stator, because the stator wire wrap cannot directly contact the cooling medium. When heat exchange is performed, the heat is difficult to diffuse, which makes the air heat inside the motor housing very high, which easily causes thermal elongation and deformation of the electric spindle, which in ...
