Brief Introduction

Meet the Z4-250-31 Separatedly Excited DC Motor from Xi'an AIMIN-your industrial operation's new cornerstone of performance, versatility, and reliability. Engineered for heavy-duty scenarios demanding precision and endurance, this separately excited DC motor redefines what critical equipment can deliver across sectors.

At its core, the Z4-250-31 boasts dual-speed flexibility (500/1500 r/min) that adapts seamlessly to variable loads-ideal for material handling, metallurgical processing, or conveyors, where tailored speed control directly boosts efficiency. Its 400V rating aligns with standard industrial grids, eliminating compatibility hurdles, while Class 155 (F-class) insulation offers superior thermal resilience: it thrives in 0–40°C environments, cutting overheating-related downtime and extending service life far beyond entry-level alternatives.

Built for durability, premium bearings (6313/C3 at the drive end, 6216C3 at the non-drive end) handle high radial loads with minimal friction, ensuring smooth, continuous operation. The IM B3 mounting configuration enables effortless integration into existing layouts, while IP21S protection shields components from industrial dust and light moisture-perfect for harsh workshop settings.

Crafted by Xi'an AIMIN (a leading motor engineer with proven expertise), this December 2025-produced unit (1060kg robust frame) is backed by strict quality control and dedicated support (TEL: +86 400 029 1177). Its separately excited design delivers unrivaled speed regulation precision, while energy-efficient performance slashes long-term power costs.

Whether upgrading aging gear or outfitting new lines, the Z4-250-31 Separatedly Excited DC Motor isn't just a motor-it's a strategic investment: rugged, adaptive, and trusted to keep your operations faster, longer, and more profitable.
