The Low Voltage AC Motor YE3 series from Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. covers frame sizes 80 to 450 and power outputs from 0.75 kW to 1000 kW. This three-phase squirrel cage induction motor meets IE3 premium efficiency standards under IEC 60034-30, carries IP55 ingress protection, and supports supply voltages of 380 V, 400 V, 415 V, and 660 V. Bearing configurations using SKF, NSK, or FAG components are available on request.
Manufacturer and Supplier Background
Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. has more than 20 years history, and has established cooperation with more than 30 motor manufacturers. Our partner brands include ABB, Siemens, Wolong, NEC, SIMO, PINXING, XEMC, CHANGSHA and so on.
The production is controlled by a SAP factory management system, which registers every step from the intake of raw materials to the final assembly and exit inspection. Each product is made by well-known companies and goes through quality testing before being shipped.
Common Application Challenges
Challenge | How the YE3 Addresses It |
High energy costs from inefficient motors | IE3 premium efficiency class reduces power consumption relative to IE1 and IE2 motors |
Motor failure in dusty or wet environments | IP55 protection blocks dust ingress and water jets from any direction |
Voltage mismatch with local grid | Supports 380 V, 400 V, 415 V, and 660 V without additional transformer equipment |
Bearing wear causing unplanned downtime | SKF, NSK, or FAG bearing options available to match your maintenance standards |
Limited frame size availability | Frame range 80–450 accommodates a wide variety of machine mounting configurations |
Technical Specifications
The YE3 is a three-phase squirrel cage induction motor built to IEC standards. Operating at IE3 premium efficiency, it generates less heat and lower power loss compared to IE1 or IE2 motors.
The IP55 rating protects the motor in environments with airborne dust and water jets, making it suitable for factory floors with washdown requirements and many outdoor installations.
Voltage compatibility across 380 V, 400 V, 415 V, and 660 V means the motor can be matched to regional grid specifications in most markets without additional conversion equipment.

Production and Quality Process
Each YE3 item is manufactured with the SAP factory management system which records the manufacturing status at each stage. The stator windings are wound and insulated for the thermal and electrical load of continuous duty. Rotor balancing is conducted to minimise vibration at rated speed. Each device is tested before shipment for insulation resistance, no-load current and temperature rise.
The company’s technical team can accommodate dimensional changes to meet unique customer mounting needs.
Industry Applications
The YE3 low voltage ac motor is used across a range of industrial sectors:
· Machine tools — Stable torque for CNC and conventional machining
· Water pumps — Continuous duty in municipal and agricultural water supply
· Fans and ventilation — Airflow control in HVAC and industrial ventilation systems
· Compressors — Sustained power for air and refrigeration compressor drives
· Food processing — Suitable for clean, non-corrosive operating environments
· Printing and packaging — Consistent speed for web and sheet-fed equipment
· Agricultural machinery — Durable performance in field and processing applications
· Conveying and mixing — Handles variable load in conveyor and blending systems
The YE3 is not rated for environments containing flammable, explosive, or corrosive gases. A dedicated explosion-proof motor series is required for those conditions.
Customization Options
Bearing brand selection — SKF, NSK, or FAG — is available based on your maintenance standards or regional availability. Frame dimensions can be adjusted to match existing equipment mounting configurations.
Freight arrangements are planned per order and support sea, land, air, and multimodal combinations. This is particularly relevant for large-frame motors or project-based bulk orders.
For specific efficiency class or voltage requirements, the team provides model recommendations based on your actual operating conditions.
