Decoupling analysis of a novel bearingless flux-switching permanent magnet motor

AIP Advances, 2017
In this paper, a novel 12/10 stator/rotor pole bearingless flux-switching permanent magnet (BFSPM) motor is proposed to overcome the drawbacks of rotor permanent magnet type bearingless motors. The basic motor configuration, including motor configuration

Research on Displacement Sensorless Control for Bearingless Synchronous Reluctance Motor Based on the Whale Optimization Algorithm–Elman Neural Network

Actuators
The unique structure of bearingless motors requires extra displacement sensors to monitor rotor movement, unlike conventional synchronous motors. However, this requirement inevitably escalates the cost and size of the motor. To address these issues, this

A Novel Grey-RSS Navigation System Design for Mobile Robots

International Journal of Automation and Smart Technology, 2012
The active magnetic bearing (AMB) offers several advantages such as having no friction, high rotational speed, less energy loss, and long life span. In rotation application, however, it must be connected to a motor which may degrade its performance.

Conical Bearingless Motor/Generators [PDF]

, 2008
Motor/generators based on conical magnetic bearings have been invented as an improved alternative to prior such machines based, variously, on radial and/or axial magnetic bearings. Both the present and prior machines are members of the class of so-called
