Problems solved by technology

[0003] Based on the above inventors' discovery, the existing methods mainly have the following disadvantages, such as: when using a servo motor in an environment containing dust, because the front end of the rotating shaft is provided with a raised slot connected to the CNC machine tool transmission, resulting in high-speed rotation The rotating shaft in the center is easy to form a fine air pressure, which drives the dust in the air to float in the air around the rotating shaft, so that part of the dust enters the connecting end face of the NdFeB magnet and the servo motor, resulting in the tight fit of the NdFeB magnet. Alteration of equipment accuracy due to contact with dust

Abstract

The invention discloses an automatic cooling type motor for a numerically-controlled machine tool. The structure of the motor involves a transmission mechanism, a protective shell, a metal connector and a driver; and the transmission mechanism is fixedly embedded in the end face of the inner side of the protective shell, the right side face of the upper end of the protective shell is fixedly connected with the metal connector in an embedded mode, the metal connector is located over the driver, and the driver is embedded in the end face of the right side of the transmission mechanism. Air in apiston ring is extruded along with submerging of all the swing blocks into the gap, the air in the piston ring is sprayed out through a piston opening, gas explosion is formed, dust attached to the outer side of the transmission mechanism is removed, and the situation that the precision of equipment is affected by the dust of the motor can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of numerical control machine tools, and more specifically relates to a motor for automatic cooling type numerical control machine tools. Background technique [0002] The rotor inside the servo motor is a permanent magnet. The U / V / W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder of the motor feeds back the signal to the driver. Values ​​are compared to adjust the angle at which the rotor turns. The accuracy of the servo motor depends on the accuracy of the encoder. [0003] Based on the above inventors' discovery, the existing methods mainly have the following disadvantages, such as: when using a servo motor in an environment containing dust, because the front end of the rotating shaft is provided with a raised slot connected to the CNC machine tool transmission, resulting in high-speed rotation ...
