Design of coreless axial flux permenent magnet generator for wind power generation
Project Area of Specialization Mechatronics EngineeringProject SummaryToday the electrical motors are embedded in almost every market segment in the industry, providing a smarter, safer, and efficient alternative to cope with the workload. A difficult challenge to the electric motor is to compete with hydraulic motors, where the torque density requirement is beyond any machine design today. In order to build a torque dense electrical machine, the geometrical dimensions must be small while the current densities are high, which results in a low efficient machine.
The low efficiency implies that the machine has high losses, and must be very efficiently cooled. Focus on high ef?ciency and invention of high-performance permanent magnets (PMs) has “reinvented” their use in electric machines today. A high magnetic remanence and demagnetization capabilities make it possible to replace the ?eld-winding in brushless synchronous machines, resulting in a compact machine design with high ef?ciency and performance. The axial ?ux brushless PM machine (AFPM) has gained signi?cant interest due to this and opened a broad application variety within all power ranges.
The axial flux permanent magnet motors today needed to be optimized for industrial application as it has higher efficiency, high power factor as they are synchronous motors and addition to that they have other advantages like air gap adjustment because of their air gap geometry. First of all, it employs a permanent magnet which would save a lot of power losses that occur in the winding. Secondly, it uses the axial flux geometry which has the advantage of an easily adjustable air gap. Optimized design of such motors would take the capability of motors to the next level in terms of efficiency and required operating power. Also, the permanent magnet motor can be useful in constant speed application in industries and it can replace the small and the medium size of the motor.
The development of an axial-flux permanent-magnet generator for a gearless wind energy system aims to demonstrate the feasibility of integrating wind and photovoltaic energy converters for the generation of electricity and to achieve optimum exploitation of the two energy sources. The merits of an axial-flux generator topology are discussed with reference to the particular requirements of an electrical generator for a direct-coupled wind turbine application. The design, construction, and test results of a 5 kW, 200 rev/min permanent-magnet generator, to form a 10 kW pilot power plant with a 5 kW photovoltaic array, are presented.
Project ObjectivesOur aim is to design an optimal electromagnetic layout for a generator having maximum efficiency, low-cost, durability, power output, and weight.
- Technology startups such as Magnax claim that electric motors and generators based on axial flux technology will be a step-change in efficiency, size, reliability, and cost-effectiveness versus the current generation of direct drive machines (based on Radial Flux).
- The main objective is to design an Axial Flux double phase generator that can generate the optimum power even at low wind shear.
- To design Permanent Magnet based Axial Flux Generator with maximum Power Output comparative to Radial Flux Generator even at very low rpm.
- The downsizing and a sleek outlook of the product which is intended to perform optimum desired functions.
The output we hope to achieve is to introduce a better effective method to generate electricity that we can have high output power with minimum input resources. And when we want mechanical work to do, so we can have high mechanical output with less electric input and in this project, we display wind power, RPM, and voltage.
Benefits of the Project- By this project, we can overcome the losses of flux, power, and voltage drop.
- A vertical wind turbine is very helpful to make power and our project is implemented to national or superhighways, due to this we can make power easily even the force of air is minimum.
- The vertical wind turbine is more powerful as compared to horizontal wind turbines.
- This project gives more power as compare to other normal motors.
- Space which is required is very less as compared to other wind turbines.
- When this project is implemented on the highway, so by this work out we can easily supply a voltage or power to street light and other source which need power.
