Abstract

The invention provides a method for core pulling and penetrating of a motor. The method comprises the steps of preparation, lifting, hoisting, core pulling and core penetrating. The core pulling and the penetrating of the large main driving motor can be achieved by changing an initial lifting position of a rotor, without changing a lifting rope; and the method effectively solves the problems that a core pulling and penetrating field of the large main driving motor is narrow and small, the time is consumed by changing the lifting positions of the rotor for many times, and the labor intensity is increased by connecting and dismounting a short shaft.

Description

technical field [0001] The present invention relates to the technical field of electromechanical engineering, in particular, to a method for pulling out a core of a motor. Background technique [0002] Due to the defects in the early design and manufacture of the old main drive motor, the design strength of the rotor magnetic pole bolts is low, resulting in the sudden magnetic pole bolt rupture of the main drive motor under normal operation, and the automatic power failure of the motor occurs frequently. In order not to affect the production plan, it is necessary to replace the new or stronger pole bolts frequently in the maintenance of the main drive motor engineering. Therefore, in the maintenance process of replacing the pole bolts of the large main drive motor, the core pull-through method of the main motor is the most critical. [0003] At present, in the construction of replacing the pole bolts, the short-axis method is generally used to pull out the core of the rotor...
