Copper Copper Rotor Bars and Copper End Rings with Long service life
Copper rotor bars are an important part of a motor. This is especially true of induction motors. They have a vital role in the conversion of electrical energy into mechanical energy and the generation of rotational motion in the motor. Barrels are typically manufactured from copper and are strategically located within the core of the rotor.
The main function of the rotor bar is the transmission of the induced current within the rotor of the induction motor. When the motor is energised, a rotating magnetic field is created in the stator windings. This rotating magnetic field in turn generates a current in the rotor bar by means of electromagnetic induction.
The rotor bars, being made of conductive material, allow the induced current to flow through them. As the current flows, it creates its own magnetic field, which interacts with the stator's rotating magnetic field. This interaction establishes a torque that causes the rotor to rotate.
The shape, size, and arrangement of rotor bars affect the motor's performance characteristics, such as torque, efficiency, and starting capability. The design of the rotor bars must be carefully engineered to optimize motor performance and ensure reliable operation.

About us:
Jiangyin Electric Alloy Co., Ltd., formerly known as Jiangyin Electric Alloy Factory, was established on June 12, 1985. It is mainly engaged in the research and development, production, and sales of high-speed rail supporting products. Its main products are copper alloy deep processing products, including railway contact wires, railway load-bearing cables, copper alloy busbars, and other copper components.
Since its establishment, the company has been committed to providing customers with high-quality copper alloy products and services with advanced management systems, strong research and development capabilities, excellent product quality, and comprehensive services.
It has successively cooperated with railway bureaus under the Ministry of Railways, such as Shanghai, Guangzhou, Beijing, Zhengzhou, Chengdu, and other railway bureaus; Locomotive and motor production enterprises of the Ministry of Railways, such as CRRC and national motor and electrical appliance production enterprises, as well as well-known domestic and international enterprises such as Xiangtan Electric, Dongfang Electric, Schneider Electric, Siemens, ABB, GE, etc., have established strategic cooperative relationships and become a licensed supplier of copper and copper alloy stranded wire and contact wire for the China Railway Group Electric Gasification Bureau.
We provide technical support and services for copper contact wire, including:
