YXKK355-4SZ  Three-phase Asynchronous Motor

Brief Introduction

The AIMIN YXKK355-4SZ 355kw motor is a flagship high-voltage, high-power three-phase asynchronous motor meticulously engineered and manufactured by Xi'an AIMIN Motor Co., Ltd., a leading enterprise in China's motor industry with decades of experience in crafting industrial-grade drive solutions. Tailored explicitly for heavy-duty, continuous-operation scenarios, this motor is engineered to serve as the core power unit for critical industrial equipment, including large-scale ventilation fans, high-pressure compressors, heavy-duty conveyors, and industrial pumps in sectors such as petrochemicals, power generation, and metallurgy.

Designed to operate on a 50 Hz power grid, the YXKK355-4SZ 355kw motor boasts a rated output power of 355 kW, a stator voltage of 10000 V, and a rated stator current of 25.6 A, delivering a nominal speed of 1485 rpm-ideal for applications requiring consistent, medium-speed torque delivery. Its electrical design adopts a Y-connection (star connection) configuration, ensuring balanced three-phase current distribution and reducing load imbalance on internal windings. The motor is rated for S1 continuous duty, meaning it is constructed to run at full load 24 hours a day, 7 days a week, without performance degradation or overheating risks, a critical design feature for industries with non-stop production schedules.

In terms of environmental adaptability, the YXKK355-4SZ excels in diverse working conditions. It is rated to operate in ambient temperatures ranging from -15°C to 40°C and at altitudes up to 1000 meters, making it suitable for both cold northern industrial zones and moderate-altitude manufacturing facilities. The motor is fitted with high-precision bearings: NU222ECM on the drive end (D.E.) and 6222/C3 on the non-drive end (N.D.E.), selected for their high load-bearing capacity and low-friction operation, which ensures smooth rotation and minimizes mechanical wear during long-term use. Weighing 2890 kg, its robust cast-iron frame provides exceptional structural stability, dampening vibration and ensuring alignment with driven machinery- a requirement highlighted in the motor's cautionary guidelines for coupling installation.

From a compliance and quality perspective, the YXKK355-4SZ adheres strictly to the Q/XD.510.316 enterprise standard, a rigorous benchmark for high-voltage motor manufacturing, and holds CE certification, verifying its compliance with European Union health, safety, and environmental protection regulations. This dual compliance ensures seamless integration into both domestic Chinese industrial systems and global supply chains, eliminating regulatory barriers for international customers. Produced in December 2026, this unit benefits from Xi'an AIMIN's latest manufacturing techniques and quality control processes, further guaranteeing product consistency and reliability.

The AIMIN YXKK355-4SZ 355kw motor stands out in the high-power motor market due to a suite of targeted advantages that address the core pain points of industrial users: First, industry-leading energy efficiency-with a 93.2% efficiency rating and a 0.86 power factor, it drastically reduces energy consumption compared to standard motors, translating to substantial long-term cost savings on electricity bills for high-volume operations. Second, enhanced thermal and mechanical durability-Class 155 insulation provides superior resistance to high temperatures, while the heavy-duty bearing configuration and S1 duty cycle rating ensure an extended service life and minimal unplanned downtime. Third, unmatched environmental versatility-its ability to operate across a wide temperature range and at moderate altitudes makes it a flexible solution for diverse industrial settings, eliminating the need for custom modifications. Fourth, global compliance and compatibility-CE certification and standardized mounting dimensions enable easy integration into existing equipment worldwide, simplifying retrofits and new installations alike. Finally, trusted brand support-backed by Xi'an AIMIN's comprehensive after-sales network, including technical consultation, spare parts supply, and on-site maintenance, users gain a reliable partner for the entire lifecycle of the motor, ensuring maximum operational uptime and return on investment.
