Brief Introduction

The YJTKK series variable frequency speed three-phase asynchronous motor, manufactured by Xi'an AIMIN ELECTRICS Co., Ltd., is a high-performance industrial drive designed for heavy-duty applications requiring precision control and reliable operation. Taking model YJTKK355-4 315 kw motor as a representative, this series integrates advanced electrical and mechanical design to deliver outstanding efficiency, durability, and flexibility.

Robust Construction: IP55 ingress protection shields against dust and water ingress, while IC666 cooling ensures effective heat dissipation even under continuous S1 duty. Class 155 thermal insulation enhances resistance to temperature fluctuations, extending component lifespan.

High-Quality Bearings: Equipped with NU222ECM (drive end) and 6222/C3 (non-drive end) bearings, it withstands heavy radial and axial loads, minimizing maintenance needs and ensuring stable long-term operation.

Compliance & Safety: CE-certified and manufactured under standard Q/XD.510.316, it adheres to strict quality and safety norms, with built-in safeguards against improper operation (e.g., forbidden earth-connected winding operation).

The YJTKK355-4 315 kw motor delivers a rated power of 315 kW at 10000 V stator voltage, generating 2006 N·m of torque at 1485 r/min (50 Hz). It achieves an energy efficiency of 92.2% and a power factor (cosφ) of 0.84, significantly reducing energy consumption compared to standard motors. Its design ensures consistent performance at ambient temperatures up to 40°C and altitudes up to 1000 m, making it suitable for challenging industrial environments.

This series is ideally suited for heavy industrial sectors where reliability and efficiency are critical:

Mining & Metallurgy: Driving crushers, conveyors, and rolling mills that require variable speed and high torque.

Petrochemical & Power Generation: Powering pumps, fans, and compressors under continuous operating conditions.

Cement & Steel: Supporting heavy-duty machinery with precise speed control to optimize production processes.

By combining high efficiency, flexible operation, and robust durability, the YJTKK series 315 kw motor stands as a reliable choice for industries seeking to enhance productivity while minimizing operational costs.
