Description

Technical Field

[0001] The present invention relates to the technical field of excitation motor coil fixing, and in particular to a coil fixing device for an excitation motor. Background Art

[0002] An excitation motor is a motor used to generate and maintain the magnetic field required in generators, motors and other equipment. Its working principle is mainly based on the basic principles of electromagnetic induction and electromagnetic force. When the excitation current passes through the excitation coil, a magnetic field is generated between the stator and the rotor. This magnetic field can be divided into two parts: the excitation magnetic field and the induced magnetic field. The excitation magnetic field is directly generated by the excitation current, while the induced magnetic field is generated by the interaction of the magnetic fields between the stator and the rotor.

[0003] A coil is a fundamental element in electromagnetism, consisting of a looped structure wound with a conducting wire. Coils are widely used in electrical engineering and electronics, and their function and effect depend primarily on the type and usage of the coil. The design and application of a coil require consideration of parameters such as inductance, resistance, number of turns, and material to meet the needs of different application scenarios.

[0004] When using an excitation motor, it is usually necessary to wind the coil onto the stator to form an excitation winding. When DC current is passed through the stator coil, a constant magnetic field is generated. The position and function of the coil are to generate and maintain the required magnetic field to achieve normal operation and energy conversion of the motor. At the same time, after the coil is wound on the stator, it is usually necessary to use a fixing device to fix the stator.

[0005] In the process of fixing the stator using a fixing device, the existing fixing method is to position the stator by a positioning mechanism and then fix the stator by multiple bolts. This results in the need to use tools to install and remove multiple bolts one by one during the installation and removal process, which makes the installation and removal process more cumbersome, inconvenient for quick installation and removal of the stator, and is not conducive to the use of the fixing device.
