Permanent magnet structure design of outer rotor radial flux permanent magnet generator for reduction cogging torque with design of experiment

Abstract

Radial flux permanent magnet generator have higher output voltage and torque capability than axial flux II. DESIGN OF OUTER ROTOR RADIAL FLUX PERMANENT permanent magnet generator. The efficiency is also higher than MAGNET GENERATOR axial flux permanent magnet due to the lack of rotor windings have high power density and torque per current ratio , but the The conventional RFPM generator is classified into innerlarge cogging torque can be generated. Cogging torque would be rotor and outer-rotor types.the source of acoustic noise and vibration. It reduce very important for initial activation of wind turbine. In this paper , we are designed of outer rotor radial flux permanent magnet generator which is integrated within blade and then the pole arc ratio and magnet structure was designed in order to reduce the cogging toque.

Design and Performance Analysis of a Grid-Connected Distributed Wind Turbine

“…Since the study's primary goal is to improve our utility grid's overall resiliency by integrating more distributed wind turbines to serve households in Lubbock, TX, the height that we used was within the standard limit for a suburban area [15].…”

“…Considering the maximum construction limit in a suburban area and maximum wind velocity, the desired output power is considered to be 6 kW [15] (Equation ( 1)). As stated by Betz Law, for wind power extraction, kinetic energy extraction of over 59.3% is not possible for any wind turbine system.…”

“…Besides these impacts, several harmful chemicals now imbalance the ideal ingredient ratios of air required for safe breathing [7]. As shown in the report regarding global energy generation, large-scale renewable-based electricity generation can directly minimize the use of fossil fuel generators [8][9][10][11][12][13][14][15]. Indeed, the renewable energy conversion technique has a very low impact on the environment compared to fossil fuel-based system, and its environmental impact is negligible as it produces fully clean energy via clean natural sources [16][17][18][19][20].…”
