In the commercial market, motor laminations are usually divided into stator laminations and rotor laminations. Motor lamination materials are the metal parts of the motor stator and rotor that are stacked, welded and bonded together, depending on the needs of the application. . Motor lamination materials are used in the manufacture of motor units. These materials improve the performance of the motor and reduce losses. The motor lamination process is an integral part of the motor design. The selection of motor lamination materials is critical, temperature rise, weight , cost, and motor output are some of the key characteristics that are strongly influenced by the type of motor laminate used, and the performance of the motor is largely dependent on the motor laminate used.
There are many types of motor laminates in the commercial market for motor assemblies of different weights and sizes, and the choice of motor laminate material depends on various criteria and factors such as permeability, cost, flux density, and core loss. The machining of the motor lamination material can have a large impact on the efficiency of the unit being assembled. Adding silicon to steel can improve electrical resistance and magnetic field capability, and silicon increases the corrosion resistance of motor laminate materials. As a steel-based product for motor laminate materials, the demand for steel-based products is outstanding. Silicon steel is the preferred material in the motor laminate material market.
In the case of a solid core, the eddy currents measured are much larger than those that occur in a laminated core, where a lacquer coating is used to form an insulator to protect the laminations, the eddy currents cannot be seen in the transverse direction. The upward flow of the cross-section thus reduces eddy currents. Adequate varnish coating ensures that the armature core laminations remain thin The main reason – both for cost considerations and for manufacturing purposes, modern DC motors use laminations between 0.1 and 0.5 mm thick. It is not enough that the laminate has the correct thickness level, most importantly, the surface must be dust-free. Otherwise, foreign bodies may form and cause laminar faults. Over time, laminar flow failures can cause core damage. Whether bonded or welded, the laminations may be loose and are preferred over solid materials.
The growing demand for high-efficiency electric motors has significantly increased the demand for new motor laminate materials. During the forecast period, the expansion of end-use industries such as industrial, automotive, oil and gas industries, and consumer goods will increase the demand for composite materials for motor laminates. generate huge demand. Major manufacturers are working to reduce the size of motors without changing prices, which will further create demand for high-end motor laminates. In addition, market players are investing heavily in the development of new motor laminate materials in order to improve motor performance and reduce heat loss. Amorphous iron and nanocrystalline iron are some advanced motor laminate materials currently used. The manufacture of motor laminate materials requires a large amount of energy and mechanical force, which further increases the overall manufacturing cost of motor laminate materials. Furthermore, fluctuations in raw material prices may hinder the motor laminates market.
The growing construction industry requires advanced construction equipment to meet unmet demand, and as the construction industry expands, the industry is expected to create room for growth for motor laminate manufacturers in North America and Europe. India, China and Ocean and other Pacific countries are likely to create the best opportunities for motor laminate manufacturers due to industrial expansion and expansion in the automotive and construction sectors. Rapid urbanization and increasing disposable income in Asia Pacific will boost the growth of the motor laminates market. Latin America, Middle East Africa, and Eastern Europe are emerging as emerging regions & manufacturing hubs for automotive assemblies, which are expected to generate significant sales in the motor laminates market.
