YJTKS4501 VVVF AC Squirrel Cage Induction Motor 450kW

Title:

YJTKS4501 VVVF three-phase Asynchronous Motor 

Brief Introduction

Designed by Xi'an SIMO Motor -a trusted leader in industrial electromechanical solutions-the YJTKS4501-6XJ is a high-power AC squirrel cage induction motor built to tackle the most rigorous industrial demands. With a 450 kW rating and 990 r/min synchronous speed, it delivers a formidable 4297 N·m of torque, providing the muscle needed for heavy, non-stop operations while maintaining exceptional efficiency.

Standout Attributes

Industry-Leading Efficiency: Boasting a 94.5% efficiency rating and 0.88 power factor, this AC squirrel cage induction motor minimizes energy consumption, directly reducing operational expenses and supporting sustainability targets for industrial facilities.

Dynamic Speed Adaptability: The 5–50 Hz frequency range offers precise, stepless speed control, letting operators fine-tune performance to match variable load conditions and maximize process efficiency.

Built for Harsh Environments: With an IP54 ingress protection rating and IC 86W cooling system, it resists dust, water spray, and ambient temperatures up to 40°C. F-class (155°C) insulation and heavy-duty dual bearings (NU228ECM/6226/C3) ensure long-term reliability and minimal maintenance, even under extreme stress.

Ideal Use Cases

This AC squirrel cage induction motor is the workhorse behind critical operations in mining, cement manufacturing, water treatment, and metallurgy, driving large pumps, fans, compressors, and conveyor systems. Its S1 continuous duty cycle and stable torque output make it a go-to choice for applications where downtime is not an option.
