摘要

本文提出了一种检测无轴承电机角度的方法，该方法可减少电流造成的磁干扰。无轴承电机的悬挂绕组和电机绕组会产生漏磁通。由于这种电磁现象，用于角度检测的线性霍尔效应传感器的信号会受到干扰，因此必须避免在绕组附近放置传统的霍尔传感器。为解决这一干扰问题，本文阐明了传感器位置与集中绕组无轴承电机的极数和槽数之间的理想组合。

Proposal of angle detection method for concentrated winding bearingless motors with less magnetic interference due to current

This paper proposes a method for detecting the angle of a bearingless motor with less magnetic interference due to the current. Bearingless motors have suspension windings and motor windings that generate leakage flux. Owing to this electromagnetic phenomenon, the signal of the linear Hall-effect sensor for angle detection is disturbed, and it has to be avoided to place Hall sensors near the winding conventionally. To solve this interference problem, this paper clarifies the ideal combinations between sensor positions and the number of poles and slots of concentrated winding bearingless motors.
