Design of Coreless Motor for Artificial Blood Pump
In order to solve the existing problems of poor stability and low efficiency of blood pump motors,a coreless micromotor for blood pump with diameter of 4.8 mm and rotation speed of 35 000 r/min was designed.The coreless motor was adopted in the structure to avoid the cogging effect and reduce the eddy current effect.Based on ANSYS Maxwell finite element analysis software,the structural design and performance analysis of coreless motor were carried out by RMxprt module,and the three-dimensional finite element simulation model of coreless motor was established by Maxwell3D module.On this basis,the electromagnetic data of the coreless motor in working state were obtained through the simulation under static magnetic field,no-load and rated load,and the electromagnetic design performance of the coreless motor was analyzed.The results show that the designed coreless motor for blood pump has reasonable design and good electromagnetic performance,and the efficiency of coreless motor is about 79%.This study provides a reference for the design and optimization of coreless motor for blood pump.
