Z4-200-31 Direct Current Elektromotor 55kw 440V IC06 S1

Brief Introduction

The SIMO Z4 Series Direct Current Motors, represented by the Z4-200-31 elektromotor 55kw model shown, stand as a benchmark of reliability and precision in industrial power transmission, engineered by Xi'an SIMO Motor Co., Ltd. Built to meet the most demanding requirements of modern industrial applications, these motors combine robust mechanical design, advanced electrical engineering, and strict quality control to deliver consistent, efficient performance under continuous or variable load conditions.

At the core of the Z4 Series is a modular, separately excited design that enables precise speed regulation, making them ideal for applications requiring adjustable torque and rotational speed, such as metallurgical rolling mills, heavy-duty machine tools, printing presses, and material handling systems. The Z4-200-31 elektromotor 55kw unit, for example, features a rated power of 55 kW, a rated voltage of 440 V, a rated current of 140 A, and a rated speed of 1000 rpm, with an excitation current of 8.2 A. This configuration, paired with Class F (155°C) thermal insulation and an IP21S protection rating, ensures stable operation even in harsh industrial environments with temperatures ranging from 0 to 40°C and altitudes up to 1000 meters.

The mechanical construction of the Z4 Series prioritizes durability and low maintenance. The motors are equipped with high-quality C3 clearance bearings (6314/C3 for the drive end and 6214/C3 for the non-drive end), designed to handle heavy radial and axial loads while minimizing friction and wear over long service life. The IM B3 mounting configuration allows for flexible installation in a wide range of equipment setups, while the 525 kg unit weight reflects the heavy-duty build quality, ensuring structural integrity under continuous vibration and stress.

Electrical performance is optimized for efficiency and reliability. The separately excited (SEP.180) excitation system provides independent control of the armature and field circuits, enabling smooth, precise speed adjustment across a wide range without sacrificing torque output. The S1 continuous duty rating confirms the motor's ability to operate non-stop at full rated power without overheating, a critical feature for industrial processes that require uninterrupted production.

Compliant with JB/T6316 standards and certified with the CE mark, SIMO Z4 Series motors (Z4-2-00-31 elektromotor 55kw as shown) adhere to strict international safety and performance requirements. Every unit undergoes rigorous testing and quality checks before leaving the factory, with traceable production records (as seen in the serial number Z26033025001 and production date of March 2026) ensuring accountability and consistency. Backed by SIMO's decades of expertise in motor manufacturing, the Z4 Series is a trusted choice for industrial operators worldwide, offering a combination of performance, durability, and low total cost of ownership that sets it apart in the competitive DC motor market.
