Description
Technical Field
The invention relates to the technical field of motors, in particular to a modularized stator interactive linear motor and an assembly method.
Background
The linear motor is used as a driving device for directly converting electric energy into linear motion, and is widely applied to the fields of rail transit, precision machining, logistics conveying and the like due to the advantages of high precision, high response speed and the like. The stator is used as a core component of the linear motor, and the structure and the performance of the stator directly influence the overall reliability and the running efficiency of the motor.
At present, the stator of the linear motor mainly has two forms, namely an integrated long stator and an assembled modularized stator. The integral long stator has strong structural integrity, but is easy to bend or permanently deform due to the fact that the integral long stator is large in length and poor in rigidity in the transportation and hoisting processes, so that the magnetic circuit is asymmetric, the motor performance is further affected, and even equipment cannot be installed and used.
In order to solve the above problems, an assembled modular stator is gradually adopted, and the existing modular stator is mostly connected and fixed between modules by bolts. However, the mode has obvious defects that firstly, a large number of bolts are required to be used for fastening in the assembly process, the operation is complicated, the installation efficiency is low, the operation precision requirement on installation personnel is high, and secondly, in the high-strength and long-time operation process of a motor, the bolts are easily affected by vibration and alternating stress, the risks of loosening and even falling off are generated, the connection between stator modules is invalid, and the operation stability and the operation safety of the motor are affected.
In addition, the modularized stator generates heat due to eddy current loss and coil resistance heating in the operation process, and after each module is heated and expanded, the modules are mutually extruded, so that larger thermal stress is generated. If the stress cannot be effectively released, the whole warping or local deformation of the stator can be caused, the uniformity of an air gap between the stator and the rotor is not only influenced, the motor performance is reduced, and mechanical interference can be caused when the stress is severe, so that equipment is damaged.
