Top Choice for High Efficiency and Energy Savings: National Standard YE4 Series Ultra-High Efficiency Three-Phase Asynchronous Motors

YE4 MotorIn-Depth Analysis: Hidden Champions Driving the Green Transformation of Industry

Against the dual backdrop of accelerating progress toward the “dual carbon” goals and fluctuating industrial electricity costs, enterprises“ demands for production equipment energy efficiency have shifted from mere compliance to pursuing the ultimate. As the powerhouse of industrial operations, the energy efficiency level of motors directly determines the operational costs of entire production lines. In this evolving landscape,YE4 Motor(Super-efficient)three-phase asynchronous motor) is no longer merely a technical term, but has become a key investment direction for manufacturing enterprises to reduce costs, increase efficiency, and enhance market competitiveness.

I. What is a YE4 Motor? Redefining the Standard for “High Efficiency”

What we need to make clear is that,YE4 MotorRepresents the current Level 2 energy efficiency standard in the national standard GB/T 28575-2020, corresponding to the definition established by the International Electrotechnical Commission (IEC).IE4 Energy Efficiency ClassCompared to the YE3 (high-efficiency) motors widely used in the current market, the YE4 features more precise design optimizations.

By adopting higher-quality cold-rolled silicon steel sheets, optimized electromagnetic design solutions, and more precise manufacturing processes,YE4 MotorSignificantly reduced copper losses, iron losses, and mechanical losses. This means that at the same output power, the YE4 consumes less electrical energy and generates less heat.This technological leap not only enhances the efficiency of converting electrical energy into mechanical energy but also significantly extends the lifespan of the insulation system, thereby improving the operational reliability of the equipment.

II. The Shift in Thinking from “Procurement Cost” to “Total Life Cycle Cost”

Many procurement managers faceYE4 MotorWhen considering the initial purchase price of an energy-efficient motor, which is often higher than that of a standard motor, many hesitate. However, from the perspective of SEO and industrial economics, this is a classic misconception. In the total lifecycle cost (LCC) of a motor,The purchase cost accounts for less than 31% of the total, while over 97% stems from electricity expenses incurred during operation.

Let's crunch the numbers: For a fan or pump system that runs continuously year-round, if we replace the standardYE3 motorReplace withYE4 MotorThe average efficiency improvement ranges from approximately 1.51 TP3T to 21 TP3T. While this percentage may seem small, in a 24/7 industrial setting, the annual electricity savings often cover the price difference between the two models.This characteristic of “short payback period and high long-term returns” makes the YE4 motor the preferred solution for industrial energy-saving retrofits.

III. Core Application Scenarios and Practical Case Analysis

YE4 MotorIt is not suitable for all scenarios, but it performs exceptionally well on equipment with high load rates and long operating times. Typical application areas include:

• Fluid Conveyance Equipment: such as centrifugal pumps, industrial fans, and air compressors;
• Continuous production line: such as paper-making machinery, textile machinery, and belt conveyors;



• High-energy-consumption industries: Chemical, cement, steel, and mining industries.

Case Study:

A large chemical plant once faced severe energy consumption overrun issues. Five outdated 132kW motors in its circulating water system operated continuously at full load. Following recommendations from energy management experts, the plant replaced all five motors with equivalent-specificationYE4 Ultra-High-Efficiency Motor。

Post-retrofit data monitoring indicates: The operating current of each motor decreased by approximately 4A, while the overall system operating efficiency improved by 2.11%. Based on the factory's industrial electricity rate of 0.7 yuan per kilowatt-hour,The equipment purchase cost was recouped in just 11 months through savings on electricity bills. More importantly, due to the reduced operating temperature rise of the YE4 motors, the subsequent equipment maintenance frequency at the plant decreased by 30%, indirectly saving a significant amount of labor maintenance costs.
