Research Of The Equipment Of Saddle-shaped Coil Winding Of Coreless Motor

Because of rotor without iron core and small inertia,coreless motor has excellent performance and broad application space.The rotor coil in the motor is one of the key factors which affect the motor performance.The extensive application of the motor makes the research and development of the coil winding equipment become more and more important.The saddle-shaped coil is arranged regularly and the utilization ratio of the magnet is high,but the research on the saddle-shaped coil winding equipment is scarce in China.In this paper,in order to study the development of automated coil winding equipment,structure and control programs have been made.Firstly,according to the design index of the winding machine,the overall plan of the winding machine is established,including the overall structure scheme and the control scheme.The structure includes a servo main motion module and a pneumatically driven auxiliary motion module.The servo main motion module consists of the main spindle motion,the cycloidal motion and the thread nose mechanism for coil forming.The structure is more compact,and the main movement and auxiliary motion help complete the winding coil system.As control mode,the centralized control mode is been selected,in order to determine the winding process.Secondly,threading mechanism and spindle mechanism,which is the key mechanism of the system in the winding equipment,have been designed and checked.The deformation of the nozzle has an important influence on the quality of the wound coil.With ANSYS finite element analysis software,the deformation and stress and strain of the line nozzle under the complicated stress condition are analyzed,and the nozzle meets the requirements.The thermal part of the main shaft will be caused by the temperature rise of deformation,the use of Workbench in the thermal analysis module,its steady-state thermal analysis;and bearing deformation for heat,check the clearance changes to meet the actual requirements.Thirdly,the modeling module is completed and the kinematic model is established.Then,the belt transfer function is analyzed,and the influence system is analyzed by bode diagram Response to the stiffness,load and other factors,supplemented by the motor model Simulink simulation test.On the one hand to verify the rationality of belt selection;on the other hand,the establishment of cycloid module model for the next speed of the experiment to provide simulation model has been made.Then,the saddle-shaped coil for the study and analysis,the coil trajectory planning.In order to determine the speed and response of the S-type and cubic polynomials,the acceleration / deceleration process is more smooth.The simulation results show that the speed response is ideal and the planned velocity signal is added to the cycloid control model established in the previous chapter.Simulation analysis planning effect.Finally,based on the above analysis,the prototype experiment is carried out to test the speed and torque of the cycloidal module and the spindle,and the subsequent speed planning analysis is carried out.The verification test of the motor speed acceleration and deceleration plan is carried out by means of the dSPACE semi-physical simulation platform.The analysis of the speed before the plan and the planned speed response and the similarities and moments is made.
