Brief Introduction

The AIMIN Z4-355-22 motor 50 hz is a robust, high-performance direct current (DC) motor designed and manufactured by Xi'an AIMIN Motor Co., Ltd., a leading provider of industrial electric motors. Built for applications demanding precise speed control, high torque, and reliable continuous operation, this model exemplifies the engineering excellence of the AIMIN Z4 series, which has become a trusted solution across industries such as metallurgy, paper manufacturing, textile production, and material handling.

At its core, the Z4-355-22 motor 50 hz delivers a rated output of 284 kW, operating on a 400 V supply with a full-load current of 782 A. What sets it apart is its dual-speed capability, offering a wide operating range of 540 r/min to 1500 r/min, which makes it adaptable to both low-speed, high-torque and high-speed, medium-torque scenarios. This flexibility is further enhanced by its separate excitation (SEP.180) design, which allows independent control of the armature and field circuits, enabling fine-tuned speed regulation and dynamic response-critical for processes like rolling mill drives and conveyor systems where precise motion control is essential.

Constructed for durability, the Z4-355-22 features a Class F (155°C) thermal rating and an IP21S protection class, which safeguards against dust ingress and water drips, ensuring reliable performance in typical industrial environments. Its IC 06 cooling system uses external air ventilation to efficiently dissipate heat during continuous S1 duty cycles, preventing thermal overload and extending the motor's service life. The motor is mounted in the standard IM B3 foot-mounted configuration, with premium bearings-6324/C3 on the drive end and 6224/C3 on the non-drive end-to minimize vibration, reduce noise, and lower maintenance requirements. Weighing 3000 kg, its heavy-duty frame is engineered to withstand the mechanical stresses of industrial operation, while compliance with the JB/T6316 standard ensures adherence to strict quality and performance benchmarks.

Beyond its technical specifications, the Z4-355-22 motor 50 hz offers tangible operational benefits. Its separate excitation design enables smooth acceleration and deceleration, reducing mechanical wear on connected equipment and improving overall system efficiency. The dual-speed capability eliminates the need for additional gearboxes in some applications, simplifying drive systems and lowering capital costs. Backed by AIMIN's extensive service network and CE certification, this motor meets international safety and performance standards, making it suitable for global deployment.

Whether powering a metal rolling line, a paper machine, or a heavy-duty conveyor, the AIMIN Z4-355-22 DC motor combines precision, power, and durability to deliver consistent performance in the most demanding industrial settings. It is a testament to AIMIN's commitment to engineering motors that not only meet but exceed the evolving needs of modern industry.
