项目摘要

Application of self-bearing motor as an actuator for an artificial heart was considered. When it is applied to an artificial heart actuator, miniaturization of the system, high efficiency, low power consumption and low heat generation is required. Moreover, the sinusoidal flux distribution between the rotor and the stator is also preferable to suppress dogging torque and realize stable levitation control Self-bearing motor is an active control system, which requires a certain type of sensor. Therefore, self-sensing is very important technique to realize miniaturization of the system.This project proposed self-sensing control technique based on the principle of differential transformer to the interior permanent magnet (IPM) type self-bearing motor. Main flux (d-axis) directional permeance is different from its orthogonal (q-axis) directional one because of the salient pole property in the IPM type motor. When the IPM type rotor rotates, the mutual inductance between the driving coil and … More the control coil varies with not only radial displacement but also its rotation angle. It means that the radial direction displacement information is not detected simply from the mutual inductance independently.First, Magnetic field analysis using finite element method was done to analyze the allocation of the interior permanent magnets of the rotor. Prototype IPM self-bearing motor was designed and fabricated from the analyzed results.Secondary, new detection method using full-wave rectification was introduced to obtain the more stable differential output and new compensation was also proposed to linearize the nonlinear characteristics of the self-sensing signal.Finally, to confirm the proposed compensation method, an internal PM type active magnetic bearing was made and tested. The result showed no interference and linear characteristics in the static experiment and accomplished stable rotation control up to 6,000rpm.From these results, we confirmed that the proposed method has high possibility and feasibility for self-sensing control of the IPM type self-bearing motor. Now we plan to improve linearized compensation and apply to the IPM type self-bearing motor for development of the available actuator as an artificial heart. Less

研究了自轴承电机作为人工心脏驱动器的应用。当其应用于人工心脏致动器时，要求系统小型化、高效率、低功耗和低发热。此外，转子和定子之间的正弦磁通分布也是优选的，以抑制跟踪转矩，实现稳定的悬浮控制。因此，自检测技术是实现系统小型化的重要技术，本课题提出了基于差动Transformer原理的自检测控制技术应用于内置式永磁（IPM）自轴承电机。由于IPM型电机的凸极特性，主磁通（d轴）方向磁导不同于其正交（q轴）方向磁导。当IPM型转子旋转时， ...更多信息控制线圈不仅随径向位移变化，而且随其旋转角度变化。这意味着径向位移信息不能简单地从互感中独立地检测出来。首先，采用有限元法对转子内部永磁体的磁场分布进行了分析。根据分析结果，设计并制作了IPM自轴承电机样机;其次，采用全波整流的检测方法获得了更稳定的差动输出，并对自检测信号的非线性特性进行了线性化补偿;最后，制作了内置永磁型主动磁轴承样机并进行了实验验证。静态实验结果表明，该方法无干扰、线性化，实现了转速高达6，000 rpm的稳定旋转控制，验证了该方法用于IPM型自轴承电机自感知控制的可行性和可行性。现在，我们计划改善线性化补偿，并应用于IPM型自轴承电机，以开发可用的驱动器作为人工心脏。少
