NdFeB magnets are used in wind power generators due to their high magnetic strength, excellent performance, and cost-effectiveness. They are commonly used in direct drive and semi-direct drive wind turbine generators, where they provide high torque and reliability at low speeds. NdFeB magnets are preferred over other magnet materials due to their high coercivity, high remanence, and excellent temperature stability. They are typically manufactured using powder metallurgy techniques and can be shaped into a variety of shapes and sizes, including discs, blocks, rings, and arc/segments. The performance grades of NdFeB magnets range from N35 to N52 or with H, SH,UH, with higher grades providing higher magnetic strength and better performance under extreme conditions.

India’s Wind Power Market
India is one of the fastest-growing wind power markets in the world, with a large number of wind turbines installed across the country. The government has set ambitious targets for renewable energy generation, including wind power, and has implemented policies that incentivize the development of wind power projects. The wind power capacity in India is expected to reach 60 GW by 2022, and the wind turbine market is expected to grow at a CAGR of 6.4% from 2020 to 2027. The growing demand for clean energy and the favorable policy environment in India are expected to drive the demand for wind turbines, including those that use NdFeB magnets.
Shapes and Sizes of NdFeB Magnets
NdFeB magnets come in a variety of shapes and sizes, depending on the requirements of the application. For wind turbine generators, the most commonly used shapes are blocks, rings, and arc/segments. Block magnets are typically used in direct drive generators, where they provide a high torque and a compact design. Ring magnets are used in semi-direct drive generators, where they provide high rotational speed and low cogging force. Segment magnets are used in both direct and semi-direct drive generators, where they provide high torque and a flexible design. The sizes of NdFeB magnets can range from millimeters to centimeters, depending on the requirements of the application.
Performance Grades of NdFeB Magnets
The performance grades of NdFeB magnets range from N35 to N52 or with H, SH, UH, with higher grades providing higher magnetic strength and better performance under extreme conditions. In wind turbine generators, higher-performance grades are typically used due to the harsh operating environment and the need for high torque. NdFeB magnets with a performance grade of N42 are commonly used in wind turbine generators due to their high magnetic strength and excellent temperature stability.
Market Prospects for NdFeB Magnets in India
The wind power market in India is expected to grow rapidly, driven by the government’s ambitious renewable energy targets and favorable policy environment. The demand for wind turbine generators, including those that use NdFeB magnets, is expected to increase significantly in the coming years. The growing awareness about the benefits of renewable energy and the need to reduce carbon emissions will further drive the demand for wind turbines. The wind power market in India is expected to offer significant opportunities for NdFeB magnet manufacturers, especially those that can offer high-quality magnets at a competitive price.

Zhongke is committed to becoming a world-renowned supplier of permanent magnet material application solutions in the field of new generation consumer electronics and energy-saving home appliances.
The company's current production process of permanent ferrite magnets is as follows: the purchased pre-fired materials are mixed according to their own formula and ingredients, and after being ball milled by a ball mill, ferrite is produced through steps such as precipitation, wet pressing, sintering, and grinding. Body magnetic tiles, ferrite magnets and other finished products. The specific production process flow chart is as follows:
The strontium ferrite calcined material (the main component is SrFe12O19) is mixed with calcium carbonate, silicon dioxide, strontium carbonate, lanthanum oxide, cobalt oxide and other ingredients according to the formula ratio.
The raw materials are added with water and pulverized by a ball mill to form a slurry, which is placed in a sedimentation tower for precipitation.
The dehydrated material formed by precipitation is made into a green body through an automatic press in a normal air environment.
The raw body is sintered at high temperature into a mature body through a wet-pressed magnetic tile electric-fired roller kiln or a wet-pressed magnetic steel gas-fired roller kiln.
The cooked blank is processed by a fully automatic grinding machine processing line to form a finished product.
The magnetic properties, appearance, size and other indicators of the magnets are inspected, packed and put into storage.
The company has applied and improved a number of advanced technologies in the industry, such as high-performance ferrite slurry stabilization technology and secondary ball milling batching technology, which has solved the quantitative problem of material added in the preparation process. And we use double coupling dispersion and fine grinding to overcome the problems of slurry agglomeration and particle size distribution consistency. The performance of the slurry obtained in the ball milling process is more stable, which reduces the unit operating time of the ball milling equipment, improves product quality, and reduces production costs.
The company uses a unique new green release agent independently developed to prepare magnetic tiles. The new green release agent is an organic combination of microbial technology and surface release treatment technology, which can degrade oil molecules, reduce the oil content of the release agent, and restore the surface. active lipophilic factor. The product is combined with the surface release process, and the release effect of the magnetic tile is improved through a new release agent, and the surface finish of the blank is improved. The demoulding technology has the characteristics of simple preparation method and convenient application, and improves production efficiency.
By transforming the sintering preheating system equipment, the company reduces the water content of the sintered green body in the kiln, greatly reduces the waste rate caused by factors such as cracking and lack of oxygen during sintering, and improves the sintering density and mechanical strength of the product. Obtain good microstructure and magnet properties. The company has also realized the sintering base temperature that products with different performances can adapt to through formula adjustment. Products with different specifications, sizes and performances can be co-fired at the same temperature, which significantly improves the production efficiency of the sintering process. In addition, in terms of veneer loading and billet loading, the company has adopted a bulk stacking method that conforms to the company's product features of small shape and light weight after many tests, realizing heavy veneer loading, good sintering atmosphere, and high sintering yield. good effect.
By optimizing the parameters of grinding machines and other processing equipment and improving the process technology, the company has improved the consistency of product thickness to ≤0.02MM within L30MM and ≤0.04MM within L50MM, and has mastered the technology of three-phase motor magnets produced by grinding tooling. Breakthroughs have been made in technical difficulties in the industry, such as product precision and stable equipment performance, and certain innovations have been achieved in technology and equipment.
The company's magnetic tile products are developing in the direction of high efficiency, low consumables, and low energy consumption. For example, through atomic substitution and compound doping, the rare earth-free ZK-5B high-performance motor magnetic tile independently developed by the company reduces the coagulation of magnetic powder, improves the orientation effect, improves the material performance and reduces the production cost by using strong magnetic field to suppress and adding a double dispersant.
