Brief Introduction

The AIMIN YJTKK series is a high-performance vvvf drive for induction motor, engineered for heavy-duty industrial applications requiring precise speed control and energy efficiency. Manufactured by Xi'an AIMIN Motor Co., Ltd., this squirrel-cage rotor motor is designed to operate reliably with variable frequency drives (VFDs) under 6kV or 10kV conditions, complying with GB/T 28562 standards.

At its core, the YJTKK355-2WF1 vvvf drive for induction motor features a robust welded steel box structure, optimized for durability and ease of maintenance. Its insulation system, treated with advanced VPI vacuum pressure impregnation technology, delivers exceptional resistance to voltage spikes, moisture, and corrosion, ensuring stable performance even in harsh environments. The F-class insulation (Class 155 thermal rating) guarantees long-term thermal stability, while the IP55 protection rating and IC666 cooling method provide effective dust, water, and heat management, with air-to-air cooling paths optimized for consistent temperature control.

The YJTKK series excels in energy efficiency, with efficiency ratings reaching up to 94.1%, significantly reducing operational costs for continuous-duty applications. It supports a wide speed range (5–70Hz) with excellent low-speed performance, low noise, and minimal vibration, making it ideal for pumps, fans, conveyors, crushers, and other equipment in metallurgy, power plants, cement, and chemical industries. The motor's high starting torque and overload capacity ensure reliable startup under heavy loads, while precision balancing and SKF bearings enhance operational smoothness and extend service life.

With a proven track record in demanding industrial environments, the YJTKK series vvvf drive for induction motor combines cutting-edge design, rigorous quality testing, and AIMIN's decades of motor manufacturing expertise, delivering a cost-effective, low-maintenance solution for modern industrial automation and energy-saving initiatives.
