A pico hydropower plant is an energy harvesting system that allows production using the power of water flowing in small watercourses, and distribution network. Axial Flow Flux Permanent Magnet Synchronous Generator (AFPMSG) are particularly suitable for this application, being efficient machines achieve high with dimensions. This paper presents a parametrical study several configurations topolo...

This paper presents the development of a transient thermal model of the EVO Electric AFM 140 Axial Flux Permanent Magnet (AFPM) machine based on a hybrid finite difference and lumped parameter method. A maximum deviation between simulated and measured temperature of 2.4°C is recorded after using a Monte Carlo simulation to optimise model parameters representing a 53% reduction in temperature de...

Resolvers are widely used in electric driven systems especially in high precision servomechanisms. Both encapsulated and pancake resolvers suffer from a major drawback: static eccentricity (SE). This drawback causes a significant increase in resolver output position error (RPE) which could not be corrected electronically. To reduce RPE, this paper proposes a novel structure with axial flux. Pr...

Permanent magnet Vernier machines (PMVMs) have drawn increasing attention in recent years due to the advantage of high torque density. However, inherent low power factor issue PMVMs remains a key challenge. In this paper, novel axial-flux permanent vernier machine (AFPMVM) with modular stator is proposed. Benefiting from unique separation slot structure, proposed can obtain not only improved bu...

In this paper, a new type of harmonic injection permanent magnet shape optimization method is proposed to suppress the torque ripple surface-mounted synchronous motor. The sinusoidal waveform shaping axial section added with third shaping, and sine wave are derived. optimal ratio 6:1. no combined compared. results show that design can effectively surface mounted motor obtain relatively large ou...
