Research Of Y2-632-4Type Amorphous Motor And Design Of Amorphous Core Winding Device

As the new type green soft magnetic material, amorphous alloy has strong soft magnetic properties, corrosion resistance and electromechanical coupling performance. At present, domestic and foreign scholars have done a lot of science research, which is mainly about the application of amorphous alloy strip. In the four kinds of commonly used amorphous alloy materials, the most widely used is iron-based amorphous alloy, which has strong magnetic high permeability, low excitation current, low iron loss and cheap. This study revolves around the application of amorphous alloy strip, summarizing the current research status of amorphous alloy cores at home and aboard. On the basis of previous studies, we conduct the following study:(1) The amorphous material is applied to the motor in this study. Y2-632-4type motor is selected as the research target. Redesign the stator dimensions and stator windings to ensure the magnetic flux of amorphous motor remain unchanged. Matlab is chosen as a computer aided motor design software to improve the design efficiency. By comparing multiple sets of data calculation, one of the better performance of the calculation results is selected as the design result.(2) According to the amorphous stator dimensions obtained from the motor design, amorphous stator cores is manufactured by wire-electrode cutting method, and set out the forming scheme of amorphous stator core. Different annealing scheme and different shape of steel are chosen to anneal and clamp the amorphous stacking block. The test proves that the forming effect of the amorphous stator cores is better after the amorphous stacking block clamped by octagon steel and annealed at low temperatures over long periods of time. Loss test is measured after the amorphous stator is cut. The specific loss of amorphous stator core is lower the silicon stator core’s, although there is a small amount of leakage when the magnetic energy delivers. The specific loss of amorphous stator core is about1/3of the cold rolled silicon steel without orientation core’s.(3) The finite element analysis model is built according to the calculation results. Ansoft software is selected to simulate the performance of silicon motor and amorphous motor. Basing on the two models, the basic parameters of the motors are analyzed and compared. Intuitively understand the motor performance feature under the rated state, locked-rotor state, no-load state, as well as the distribution of the magnetic circuit. Theoretically reveal the performance of the motor under various condition. The analysis results show that the amorphous motor efficiency is2%higher than that of silicon steel motor. And amorphous motor establishes the same magnetic field at t=0.023s with silicon steel motor establishes at t=0.045s.(4) In the field of power electronics, iron-based amorphous alloy strip is mainly made into toroidal cores. The amorphous strip is thin, brittle and hard, making the current core winding device difficult to adapt to the winding of the amorphous strip. By analyzing the existing toroid core winding device, the structural composition and working principle is masted. The winding device of amorphous toroid cores is designed for the special properties of amorphous alloy strip, and the performance of all part of the device is checked. UG software is selected to build a three-dimensional model of the winding device, according to the dimensions of each part obtained after the check.
