In this paper, a hexagonal magnet shape is proposed to have an arc profile capable of reducing torque ripples resulting from cogging in single-sided axial flux permanent (AFPM) machine. The arc-shaped increases the air-gap length effectively and makes more sinusoidal, which decreases density hence causes reduction torque. Cogging basic source vibration, along with noise PM machines, since it ma...

Axial flux electric motors have received a lot of attention in recent years due to successful implementations industrial or traction applications. Particularly, axial permanent magnet synchronous (AFPMSM) can be an attractive choice case high torque-density requirements when the drive environment (packaging) is geometrically limited disc-shaped motor. However, compared radial motors, machine mo...

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...

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...

Electric machines with high torque density are needed in many applications, such as electric vehicles, robotics, ships, aircraft, etc. and they can avoid planetary gears thus reducing manufacturing costs. This paper presents a novel axial-radial flux permanent magnet (ARFPM) machine density. The proposed ARFPM integrates both axial-flux radial-flux topologies compact space, which effectively im...

in the permanent magnet linear synchronous motor (pmlsm), force ripple is harmful, useless and disturbing. the force ripple is basically composed of two components: detent force and mutual force ripple. this force is influenced by the geometric parameters of the permanent magnet (pm) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stator, a...
