We offer comprehensive life-cycle support for the CDZD104 motor, including equipment supply, on-site installation and commissioning, maintenance training, spare parts provision, and ongoing technical troubleshooting services.

Advantages of CRRC CDZD104 Motor

Adhering to advanced high-speed rail motor manufacturing technology, the CDZD104 model achieves a rated efficiency of 88%, which ensures optimal energy utilization and reduces operational costs for metro operators.
Equipped with an H-class insulation system, it can adapt to temperature fluctuations and harsh operating conditions in metro tunnels, while the rated current of 250 A ensures stable load-bearing capacity, significantly reducing the risk of equipment overheating or failure.
Designed with a rated voltage of 300 V, which complies with mainstream metro traction power specifications, it is highly compatible with the power transmission and distribution equipment of most urban rail systems, lowering supporting configuration costs.
The rated power reaches 166 kW, matching the 2200 r/min rated speed to meet the traction demand of modern metro vehicles, and its power performance is stable and reliable in long-term operation.
As a mature metro traction motor model, it is compatible with well-established rail vehicle drive systems, with high part versatility and low operation and maintenance costs, making later maintenance more convenient.

The company’s rail transit products have evolved from initially focusing on diesel locomotive motors and electrical control products to electric locomotives, and now to high-speed trains and high-power locomotive electric transmission systems.

The company has established R&D platforms for electric drive systems, including motors, converters, power modules, IGBTs, and system integration. The independently developed electric drive system for the 350 km/h China Standard EMU marks Yongji Electric Machinery Co., Ltd.’s complete mastery of the core technologies for EMU electric drive systems, achieving a leap from “Made in China” to “Intelligent Manufacturing in China.”

The company’s railway mainline locomotive electric drive products currently cover more than 10 models of locomotives, including the HXD2 and HXD3 electric locomotives and the HXN3 diesel locomotive. The company’s developed EMU traction motors and control systems currently cover more than 10 models of domestic EMUs, including the CRH2, CRH3, and CRH5, holding nearly half of the domestic market share.

Equipped with over 1800 urban rail vehicles in 23 cities and 72 metro companies across China, including Beijing Metro, Shanghai Metro, and Guangzhou Metro, as well as in countries and regions such as Malaysia and Turkey, covering all mainstream urban rail traction motor types currently available domestically and internationally.

In 2016, won the bid to repair 75KW Siemens DC traction motors for the APM line electric trains of Guangzhou Metro Group Co., Ltd.;
Also in 2016, won the bid to repair Siemens and Bombardier metro AC traction motors at Xilang Depot.
