ZZJ 800 DC Motor Introduction

ZZJ‑800 series DC motors for auxiliary rolling mill drives are core power equipment dedicated to the metallurgical and steel industry. Manufactured in strict compliance with the international IEC‑34‑13 standard for auxiliary rolling mill drive motors and China's domestic GB 5227‑85 industry specification, its key dimensions, performance parameters and manufacturing processes satisfy ISO international tolerance standards. It represents a high‑end standardized supporting motor for the industry.
Technical Features
- Custom‑developed for harsh metallurgical operating conditions, this motor series withstands long‑term frequent start‑stop cycles, forward‑reverse rotation switching and periodic heavy overload impact loads. It perfectly matches key auxiliary drive equipment for steel rolling production lines, including working roller tables, screw‑down devices, looper tension rollers, shears and ingot cranes. It fully replaces legacy motor series such as ZZ, ZZK, ZZY and ZZJ2 to realize equipment iteration and upgrade.

Cooling & Protection
Totally enclosed motors have two types of cooling: natural surface cooling of the enclosure (IC0040) and forced air cooling driven by an internal fan (IC0041). Ventilated motors have three types of cooling: ducted air inlet and natural air outlet (IC17), ducted air inlet and ducted air outlet (IC37), and those equipped with an independent blower (IC16).
Applications
The ZZJ DC motor is an important power equipment in the steel industry. It is mainly used for working roller tables, press‑down devices, looper tension rollers, shears, and ingot cranes, etc.
