The winding segmented permanent magnet linear synchronous motor (WS-PMLSM) has not only a general slotting effect but also unique two-end caused by the stator and finite length passive mover, which makes detent force of WS-PMLSM possess qualities all types motors. This paper adopts physics-based multiple analytical method to study properties. First, an accurate sub-domain model is used obtain m...

In this paper, an analytical model is proposed to analyze and predict the characteristics of a double stator linear and rotary permanent magnet machine (DSLRPMM). In order to simplify the magnetic field calculation, the DSLRPMM is cut along the axial direction (z direction) and transferred into a planar one. Hence, an analytical model of the machine considered the orthogonal effect (OE) is prop...

This paper proposes a new linear fault-tolerant permanent-magnet (PM) vernier (LFTPMV) machine, which can offer high thrust by using the magnetic gear effect. Both PMs and windings of the proposed machine are on short mover, while the long stator is only manufactured from iron. Hence, the proposed machine is very suitable for long stroke system applications. The key of this machine is that the ...

Variable reluctance linear machine (VRLM), which takes advantages of magnet free, simple structure and low cost, is one the emerging candidates for long stroke application. However, due to abundant harmonics in air gap, conventional modular suffered from thrust ripple leads vibration acoustic noise problem. The force VRLM mainly caused by higher-order induced voltage detent force. To furtherly ...

A new Single-sided Variable Flux Permanent Magnet Linear Machine with flux bridge in mover core is proposed this paper. The prevents the leakage from and converts it into linkage, which greatly influences performance of machine. First, a lumped parameter model used to find suitable coil combination no-load linkage machine, reduces computational time drive storage. Secondly, machine replaces exp...

Electricity production from ocean waves with different solutions is a topic of major research interest. Many such designs are based on linear generators that inherently introduce end forces. In this paper, detent force using Maxwell Stress Tensor and induced voltage initially investigated for two winding patterns generator topology buried magnets in finite element software. Two ways overcoming ...
