摘　　要：基于无槽无刷直流电动机具有体积小、功率密度高、无齿槽转矩的特点,采用柔性印刷电路板(FPCB)技术设计了一种导管泵用无槽无刷微型直流电动机,提出了基于3D多物理场耦合模型分析方法,对导管泵用无槽无刷微型直流电动机进行了损耗分析和优化设计.结果表明:导管泵用无槽无刷微型直流电动机的铜损占整个电动机损耗的88%左右,是导致电动机发热的主要原因;在温度场仿真中,温度变化会改变电动机损耗,影响电动机输出转矩;在流场仿真模型中,电动机温度会使人体血液温度升高,影响血液相容性;流动的血液会带走部分热量,降低电动机温度;绕组优化后的导管泵用电动机输出转矩得到提高,损耗得以降低.Based on the characteristics of slotless brushless DC motor with small size,high power density and cogging torque,the slotless brushless micro DC motor for catheter pump was designed using flexible printed circuit board(FPCB)technology,and the loss analysis and optimal design of slotless brushless micro DC motor for catheter pump were conducted based on 3D multi-physical field coupling model analysis method.The results show that the copper loss of the slotless brushless micro DC motor for catheter pump accounts for about 88%of the whole motor loss,which is the main source of motor heating.In the temperature field simulation,the temperature change can change the motor loss and affect the motor output torque.In the flow field simulation model,the motor temperature can increase the human blood temperature and affect the blood compatibility.The flowing blood takes away part of the heat and reduces the motor temperature.The output torque of the pump motor with optimized winding is improved,and the loss is reduced.
