The difference between YE3 and YE2 motors

The main differences between YE3 motor and YE2 motor are reflected in the following aspects:

Energy Efficiency Level:

The energy efficiency level of YE3 motor is higher than that of YE2 motor, reaching IE3 level, with lower energy consumption and better energy-saving effect.

Motor material:

The YE3 motor uses higher grade materials, which are more durable and have a longer service life than the YE2 motor.

Protection level:

The protection level of YE3 motor is higher than that of YE2 motor, and it has better characteristics such as dust prevention, water resistance, and corrosion resistance.

Efficiency comparison:

The efficiency of YE3 motor is about 2-4 percentage points higher than that of YE2 motor, which means that YE3 motor can better utilize electrical energy and reduce energy waste. During long-term use, the energy-saving effect of YE3 motor is also more significant.

Noise comparison:

The noise of YE3 motor is about 2-4 decibels lower than that of YE2 motor, which means that the operation of YE3 motor is smoother and more in line with modern production requirements.

Maintenance cost:

The maintenance cost of YE2 motor is lower than that of YE3 motor. Due to the simpler overall structure of YE2 motor, its maintenance and upkeep costs are also lower. The structure of YE3 motor is more complex, so its maintenance cost is also higher.

Scope of application:

YE3 motor is suitable for some high-power and high-efficiency applications, such as mining, shipbuilding, metallurgy and other industries; YE2 motors are more suitable for low load applications, such as household appliances, water pumps, fans, and other fields.

Speed:

The rated speed of YE3 motor is 3000rpm or 1500rpm, while the rated speed of YE2 motor is usually lower.

In summary, YE3 motors are superior to YE2 motors in terms of energy efficiency, materials, protection level, efficiency, noise, maintenance cost, applicability, and speed. If higher energy efficiency and longer service life are required, it is recommended to use YE3 motor instead of YE2 motor. However, it should be noted that the price of YE3 motor is relatively higher than that of YE2 motor, and comprehensive consideration is needed.
