Product Overview

The YX3 series is our next-generation high-voltage asynchronous motor designed for medium- and high-voltage industrial drive applications. It has been specially optimized for operating conditions commonly found in metallurgy, power generation, chemical processing, water conservancy and municipal projects, addressing loads such as fans, pumps, compressors and belt conveyors.

Combining mature design practices with modern simulation techniques in electromagnetic design, thermal management and mechanical strength, the YX3 delivers a highly efficient, reliable and easy-to-maintain power solution.

Key Technical Features

High-Efficiency Electromagnetic Design
Uses low-loss silicon steel and optimized slot and winding configurations to reduce iron and copper losses, improving operational efficiency and lowering system energy consumption.

Thermal & Cooling Optimization
Offers IC411 (standard) and IC416 (optional forced ventilation) cooling options. CFD thermal simulation and targeted local cooling designs ensure controlled temperature rise and long service life under continuous full-load operation.

Suitable for VSD and Direct Starting
Supports both VSD (variable speed drive) and DOL operation. Under VSD operation it provides excellent torque control and grid compatibility, enabling energy savings and operational optimization.

Robust Mechanical Structure
Shaft assemblies, end shields and bearing housings are validated by finite element strength and vibration analysis. High precision dynamic balancing ensures stable behavior under start-up shocks and sudden load changes.

Reliable Insulation System
Employs Class F insulation materials with temperature rise evaluated per Class B criteria to balance long-term insulation reliability and maintenance intervals.

Modular Design & Maintainability
Key components are modular for easy on-site maintenance and spare parts replacement, reducing downtime and maintenance costs.

Applicable Industries & Typical Loads

Industries: Metallurgy, thermal/hydro/combined-power plants, power systems, chemical and petrochemical plants, water conservancy and municipal engineering, etc.
Typical Loads: Induced draft / primary / forced draft fans, circulating water pumps, feedwater pumps, compressors, belt conveyors, material handling systems and various industrial drives.

Benefits & Customer Value

• Energy Efficiency: Lower energy consumption under common operating conditions compared with comparable models, reducing operating costs and shortening payback periods.

• High Reliability: Rigorously engineered and manufactured with comprehensive testing (temperature rise, vibration, dynamic balance), suitable for continuous heavy-duty operation.

• Low Vibration & Noise: Structural and balance optimizations minimize mechanical noise, improving operating comfort and equipment life.

• Easy Maintenance: Modular construction and standardized spare parts strategy shorten repair time and lower maintenance complexity and inventory pressure.

• Excellent Compatibility: Wide coverage of voltages and frame sizes facilitates integration with existing equipment and supports VSD retrofit projects.

Quality Control & Testing

The YX3 series is manufactured under a formal quality management system and tested against international standards. Factory tests and verification include, but are not limited to:

• Insulation withstand and partial discharge tests

• No-load and loaded performance tests

• Temperature rise tests

• Vibration and noise measurements

• Dynamic balance verification

• VSD/drive commissioning tests

Complete test reports and technical documentation are provided and on-site witnessing can be arranged.

Delivery & Services

We offer complete motor supply, electromechanical packages and on-site installation and commissioning services. We can provide matching VSD solutions, soft starters or energy recovery system technical integration as required.

A comprehensive after-sales network and spare parts support are available. For each project we can supply spare parts lists, maintenance manuals and training to ensure long-term, stable operation.

Selection & Customization

The YX3 series is highly versatile. For special operating conditions (high humidity, heavy dust, high ambient temperature, frequent start/stop or non-standard speeds), we offer customized solutions such as enhanced protection levels, corrosion protection, special cooling schemes, and additional monitoring points for temperature and vibration.

When placing an inquiry, please specify: motor model (YX3), frame size, rated power, rated voltage, rated speed / pole count, cooling method (IC411 / IC416), mounting orientation, encoder/tachometer requirements, PT100 / vibration sensor needs, regenerative or energy-recovery requirements, preferred VSD brand and motor cable length, and site conditions (dust, corrosive atmosphere, altitude, etc.). Providing full operating data enables us to supply the most suitable technical specification and an accurate quotation.
