Brief Introduction

The AIMIN Z4 series DC motor, exemplified by the Z4-355-32 motor 315 kw, is a high-power industrial drive device meticulously engineered to meet stringent industrial standards. With a rated power of 315kW, rated voltage of 440V, and rated current of 787A, this motor delivers robust power output for heavy-duty operations. Its speed regulation capability ranges from 500 to 1500 r/min, supported by a separate excitation system with an excitation current of 31.3A at 180V. Designed for continuous working (S1 duty), it operates reliably under ambient temperatures of 0~40℃ and altitudes up to 1000m, adhering to JB/T6316 mechanical industry standards and CE certification. Equipped with IP21S protection grade and IC06 cooling method, it ensures stable performance in diverse industrial environments, while F-class insulation and TH.155 thermal classification enhance its heat resistance and operational safety.

The Z4 series motor 315 kw stands out with exceptional technical advantages that outperform traditional Z2/Z3 series motors. Its core strength lies in the wide-speed regulation range: achieving constant torque control below rated speed via armature voltage adjustment and constant power regulation above rated speed through field weakening, with a total speed ratio up to 1:100. The motor features a low moment of inertia, enabling rapid dynamic response to load changes, making it ideal for precision control systems. Its octagonal full-laminated structure optimizes space utilization, while the compatibility with static rectifier power supplies eliminates the need for additional smoothing reactors for 440V models, reducing system complexity and costs. Constructed with high-quality bearings (6324/C3 for drive end and 6224/C3 for non-drive end) and manufactured by Xi'an AIMIN Motor Co., Ltd., a renowned leader in motor technology, this motor guarantees long-term reliability and low maintenance, with an impressive weight of 3300kg reflecting its solid build quality.

Widely recognized as a core power component in modern industrial automation, the AIMIN Z4-355-32 motor 315 kw finds extensive applications across multiple high-demand industries. In metallurgical rolling mills, it provides stable high torque for steel plate and profile rolling, ensuring precise thickness control even under extreme load fluctuations. For metal cutting machine tools, its smooth speed regulation and high positioning accuracy meet the rigorous requirements of precision machining. In papermaking, printing, and textile industries, it delivers flexible speed adjustment to maintain consistent material tension, enhancing product quality. Additionally, it excels in cement production lines, plastic extruders, and other heavy-duty conveying systems, where its high overload capacity and continuous operation stability ensure uninterrupted production. Whether in large-scale manufacturing plants or automated production lines, this Z4 series motor serves as a reliable power source, driving industrial efficiency and technological advancement with its superior performance and adaptability.
