Title:

YJTKK400-4 Three-phase Asynchronous VVVF Motor 

Brief Introduction

The YJTKK400-4 is a state-of-the-art VVVF motor forged to excel in the most arduous industrial landscapes-from energizing high-pressure compressors in energy hubs to propelling large-scale pumps in mining operations. Unlike conventional industrial motors, it's crafted to deliver unwavering performance under relentless heavy loads, emerging as a mission-critical power backbone for sectors where downtime is untenable.

Performance: Power, Poise, and Efficiency Unified

Operating at a 10,000 V input, the YJTKK400-4 VVVF motor delivers a formidable 710 kW of power, paired with a 1485 rpm speed and 4520 N·m of torque-capabilities that outstrip many counterparts in handling nonstop, high-intensity tasks. What truly distinguishes it is its 93.7% efficiency: this not only meets global energy benchmarks to curtail operational costs but also aligns with grid needs to minimize waste, all without compromising output. For facilities balancing performance and sustainability, this motor strikes a rare, high-value equilibrium.

Durability: Forged to Endure Extreme Conditions

Where many motors falter, the YJTKK400-4 thrives. Its heat-resistant insulation bolsters electrical resilience, extending service life amid harsh temperatures, while a robust protective rating shields against dust and moisture-vital for sites with unpredictable, rugged environments. An advanced cooling system ensures steady heat dispersion, enabling nonstop operation even in 40°C conditions. Complemented by premium bearings, it reduces wear, cutting maintenance needs and maximizing uptime far beyond standard industrial offerings.

Compliance, Safety, and Global Assurance

Fully certified to international standards, the YJTKK400-4 integrates strict safety protocols: pre-start checks and precise alignment prevent avoidable damage. Backed by AIMIN's global service network, it offers seamless installation, maintenance, and support worldwide-erasing geographic barriers to reliability. Weighing 3620 kg, this motor isn't just equipment: it's a long-term, high-value investment for industries that demand performance, endurance, and global peace of mind.
