commutator manufacturers: commutator production continues to shift from foreign to domestic markets
commutator, also known as the commutator, changes the direction of the current in the motor stator winding, so that the motor rotor continuously obtains the electromagnetic force in the same direction, thereby causing the motor rotor to rotate. Commutator is one of the important and complex parts of DC motor and AC commutator motor, and it is also one of the parts with complex technology and strict requirements in motor manufacturing. In terms of structure, a typical commutator is formed by a commutator manufacturer using mutually insulated copper contact pieces to form a circle and molded into a whole with molding materials such as phenolic molding compound.
The role of the commutator: the commutator mainly has hook type, groove type, plane type and other specifications. It is refined from imported raw materials, and its product functions have reached the international advanced level. It is widely used in power tools, household appliances, automobiles, motorcycle motors and other fields; used in automobile generators, gasoline generators and other fields. The commutator plays a rectifying role, and its function is to alternate the direction of the current in the armature winding, so as to ensure that the direction of the electromagnetic torque remains unchanged. In a generator, the commutator can convert the alternating potential in the component into a DC potential between the brushes; in the electrical concept, it can convert the applied DC current into an alternating current in the component, producing a constant direction Torque.
In terms of sales volume, China is currently the world's major sales country of commutators. At the same time, with the development of technology, customers have put forward more quality requirements and higher technical indicators for the commutator, and the specifications and functions are becoming more and more diversified. Commutator manufacturers should actively improve product quality to make their products attractive in the market. The main consumers of commutators are the United States, Japan, China, Europe and other countries and regions, which account for more than 79% of the global market. Among them, China is the world's major consumer market, accounting for more than 34% of the global sales market. At the same time, India, Malaysia, Indonesia, Thailand and other Southeast Asian countries have developed rapidly in recent years, with huge market potential, and commutator production continues to shift from abroad to China. Affected by production cost factors and market competition pattern, the entire overseas commutator production will be further transferred to China. The market share of commutators in developed countries is decreasing, and the number of commutator manufacturers is small, only in a few countries such as Europe and North America, and concentrated in the field of high-grade commutators.
epidemic has affected the development of the industry to some extent. From the data point of view, it is difficult to guarantee the operating rate and downstream market demand of commutator manufacturers, and it also brings certain difficulties to commutator manufacturers. Businesses need to maintain sufficient cash flow to cope with the development of the epidemic. Despite the external environment and industry competition issues, with the recovery of the global economy, and the continuous global and Chinese attention and investment in the commutator industry, we believe that the industry's market prospects still have certain development prospects, and investment in the industry will continue to increase.
