The main difference between YE3 and YE4 motors
The main differences between YE3 and YE4 motors are reflected in the following aspects:Energy Efficiency Level，Design parameters，Performance characteristics，Application scope，Insulation performance and cooling system，Cost，Market positioning。
The main differences between YE3 and YE4 motors are reflected in the following aspects:
Energy Efficiency Level:
The YE3 motor corresponds to the international standard IE3 energy efficiency level, which is level 3.
The YE4 motor corresponds to the IE4 energy efficiency level, which is level 4 and represents a higher energy efficiency level than the YE3 motor.
Design parameters:
The rated power of YE3 motors is usually between 10 kW and 250 kW.
The rated power range of YE4 motor is wider, from 16 kW to 355 kW.
Performance characteristics:
YE4 motor can generate higher output power at the same input power, improving equipment efficiency.
YE4 motors typically have better torque characteristics and more compact structural designs.
Application scope:
YE3 motors are suitable for general industrial production fields, such as fans, water pumps, machine tools, etc.
YE4 motors are more suitable for high-end fields such as metallurgy, mining, petrochemicals, and other applications that require high energy efficiency.
Insulation performance and cooling system:
YE4 motor adopts more advanced insulation materials and structural design, with better insulation performance.
YE4 motor has optimized its cooling system to improve heat dissipation efficiency.
Cost:
Due to higher energy efficiency and design requirements, the manufacturing cost of YE4 motors is usually higher than that of YE3 motors, which is also reflected in the market price.
Market positioning:
YE3 motors are permitted for production and meet a wide range of application needs.
YE4 motor is an efficient and energy-saving product guided and promoted by the country, representing the direction of future motor energy efficiency improvement.
In summary, YE4 motors have significant advantages over YE3 motors in terms of energy efficiency, performance, and application range, but the cost is also relatively high. Users should consider the actual application needs, energy efficiency requirements, and budget comprehensively when making choices
