Description

Technical Field

[0001] This invention relates to a reluctance motor for a large electric screw press, which can be widely used in large electric screw presses. Background Technology

[0002] In electric screw presses, large electric screw presses require motors with high power and torque, necessitating large-diameter motors to meet operational requirements. Existing motors use toothed rotors and stators stamped from integral silicon steel sheets. Since these sheets are integral structures without separate splicing, the diameter of the silicon steel sheets is limited, resulting in smaller diameters that cannot meet the high power and torque requirements of large electric screw presses. Summary of the Invention

[0003] The purpose of this invention is to provide a large electric screw press reluctance motor that outputs high power and torque, reduces motor manufacturing costs, and has a fast response.

[0004] To achieve the aforementioned objectives, the present invention provides a large-scale electric screw press reluctance motor, comprising a toothed stator housing, a toothed stator embedded within the toothed stator housing, a toothed rotor installed inside the toothed stator, and a toothed rotor shaft connected to the toothed rotor via splines. The toothed stator is a composite integral toothed stator formed by stacking several layers of large-diameter toothed stator silicon steel sheet splices, each layer of which is composed of several individual toothed stator silicon steel sheets welded together via toothed stator splice joints. Similarly, the toothed rotor is a composite integral toothed rotor formed by stacking several layers of large-diameter toothed rotor silicon steel sheet splices, each layer of which is composed of several individual toothed rotor silicon steel sheets welded together via toothed rotor splice joints.

[0005] The present invention relates to a reluctance motor for a large electric screw press. The toothed stator and toothed rotor are constructed with silicon steel sheets that are assembled in a separate structure. Therefore, they are not limited by the specifications, diameter, or external dimensions of the silicon steel sheets. After assembly, they can form a large-diameter combined integral toothed rotor and a combined integral toothed stator. Thus, a high-power motor can be made to meet the high power output requirements of a large electric screw press.

[0006] The reluctance motor for the large electric screw press of this invention is a constant power motor. Therefore, the low-speed reluctance motor can achieve a high utilization rate. This means that the reluctance motor can maintain high power output even at low speeds, thereby meeting the requirements of high torque.

[0007] The present invention relates to a large-scale electric screw press reluctance motor. By using conventional silicon steel sheet specifications and employing the splicing technology of the present invention, large-diameter composite integral silicon steel sheets can be manufactured, thereby reducing the motor manufacturing cost.

[0008] In summary, the reluctance motor for the large electric screw press of this invention outputs high power and high torque, reduces motor manufacturing costs, and has a fast response. Attached Figure Description
