In order to improve the production efficiency of the product,the innovation of rotor spinning is constantly iterated.As the core component of the rotor spinning drive system,the performance of the drive motor directly determines the performance of the whole drive system.Traditional rotor spinning is presented in this paper,on the basis of drive motor,a new type of rotor spinning high-speed motor rotor slotless amorphous alloy power is put forward,and using the method of combining theoretical analysis and calculation and finite element simulation analysis to realize the new type of drive motor for amorphous alloy structural design,and then through the analysis of the electromagnetic field and electromagnetic vibration analysis to study the motor performance,Results and the main research content are shown below.1.According to the requirements of the rotor spinning drive system,taking the motor working environment and parameter requirements into consideration,the motor structure was designed to determine the overall design scheme of amorphous alloy motor.The key problems of the research include the determination of the main size of the motor,the determination of electromagnetic load,the choice of air gap length,the choice of the number of poles and slots,the choice of permanent magnet material and size,conductor selection,stator and rotor design and so on.2.The analytical basis of the simulation software Ansoft Maxwell is introduced in detail,and using the software to conduct electromagnetic simulation analysis on the motor under static,no-load and load transient conditions verifies the feasibility of the motor design scheme.At the same time,the core loss under no-load and load conditions is compared with the silicon steel motor,and the advantages of amorphous alloy motor replacing the traditional silicon steel motor are verified theoretically.3.Using Ansoft Maxwell software analysis amorphous alloy steady state bodies drive motor load gap flux density and the electromagnetic,in order to prove that amorphous alloy drive motor radial air gap flux density and radial electromagnetic force were greater than electrical silicon steel,The radial air-gap magnetic density and radial electromagnetic force of amorphous alloy drive motor and silicon steel motor are compared and analyzed in steady-state operation.4.As amorphous alloy materials characteristics are high hardness,thin,crisp,great affected by mechanical vibration,so in addition to focus on high speed rotor slotless amorphous alloy drive motor electromagnetic performance and energy saving index,study on the deformation of stator vibration is also needed.The vibration of the stator core of the amorphous alloy order vibration mode and natural frequency range,are calculated,and compared with traditional silicon steel motor;Using Ansoft Maxwell joint simulation with Ansys Workbench realizes amorphous alloy magnetic solid coupling analysis of the stator core,taking the radial electromagnetic force in the x,y,z direction of the maximum acceleration and maximum displacement of the stator as measure index analyzes the electromagnetic vibration characteristics of amorphous alloy stator iron core,comparing the analysis results with the traditional silicon steel motor,it is found that the curve change trend is consistent when two different materials are used.But at the same frequency,the shape variable and acceleration of the amorphous motor in all directions are greater than that of the silicon steel motor.
