What is the difference between YE2 motor and YE3 motor

YE3 is an ultra-high-efficiency motor, and YE2 is a high-efficiency motor, and the motor performance of the former is superior to the latter.

1. YE2 high-efficiency motor, that is, YX3 ordinary high-efficiency motor. YX3 high-efficiency motor is the first high-efficiency motor with cold-rolled silicon steel as the magnetic material in China, which is designed and developed on the basis of the Y3 motor, and the Y3 motor is the first ordinary motor designed with cold-rolled silicon steel as the magnetic material in China, and is the product of the national "cold instead of heat".

The YX3 motor was designed in 2003 and passed the appraisal organized by the Machinery Federation in September 2005. It mainly meets the level 2 energy efficiency standard of GB T18613-2002 version - that is, the energy-saving evaluation value. It also meets the requirements of the European EFF1 index.

The energy-saving evaluation value of the later GB T18613-2006 version can also be achieved.

In its detection method, the spurious loss of the motor is calculated by the input power, and the design is also based on the calculation of electromagnetic data. Before 2008, domestic motor manufacturers carried out level 2 energy efficiency filing, and energy-saving product certification, in addition to the joint venture brand, are using YX3 motors. Therefore, as a high-efficiency motor, YX3 motor is widely known in China.

2. The YE3 ultra-high efficiency motor adopts high magnetic permeability and low loss cold-rolled non-oriented silicon steel sheet, which has the characteristics of ultra-high efficiency, energy saving, low vibration, low noise, reliable performance, and convenient installation and maintenance. It can be used for compressors, fans, pumps, crushers and other mechanical equipment, as well as in petroleum, chemical, pharmaceutical, mining and other fields with harsh environmental conditions.

YE3 motor is the latest model of the state-led promotion to replace Y, Y2, Y3, YX3 series motors, in the current international energy situation is becoming more and more tight, high-efficiency motors have become the darling of the market, and will gradually replace the old models of high energy consumption Y series motors.

YE2 series is a high-efficiency three-phase asynchronous motor, YE3 series is an ultra-high-efficiency three-phase asynchronous motor, its performance indicators are higher than YE2, especially the motor efficiency index has been improved, for example, the efficiency of YE2-3KW2 is , and the efficiency of YE3-3KW2 is more, so the YE3 series motor is more energy-saving.

The YE2 motor is a high-efficiency motor, and the YE3 motor is an ultra-high-efficiency motor, and the performance indicators and energy-saving indicators of the latter are higher.

The national standards for the two types of motors are:

JB T 11707 YE2 series (technical specifications for high-efficiency three-phase asynchronous motors) and.

GB T 28575 YE3 series ultra-high efficiency three-phase asynchronous motor technical specifications

1. The production time is different.

The YE3 motor is an ultra-high efficiency motor produced in 2010.

2. The energy consumption standards of the motor are different.

The YE2 series motor is a high-efficiency Class 3 energy consumption motor.

The YE3 series motor is an ultra-high efficiency Class 2 energy consumption motor.

3. The motor level is different.

YE3 motor is an ultra-efficient motor, which adopts new motor design, new technology and new materials, and improves the output efficiency of the motor by reducing the loss of electromagnetic energy, thermal energy and mechanical energy, and is an upgraded product of YE2 series motor.

4. The efficiency is different.

YE3 series products have the advantages of high efficiency (more than 3% higher than YE2 series motors on average) and obvious energy-saving effects, which can completely replace YE2 series high-efficiency motors.

Extended Materials. When a symmetrical three-phase alternating current is introduced into the three-phase stator winding, a rotating magnetic field is generated that rotates clockwise along the circular space of the stator and rotor at a synchronous speed n1. Since the rotating magnetic field rotates at n1 rotational speed, the rotor conductor is stationary at the beginning, so the rotor conductor will cut the stator rotating magnetic field and generate an induced electromotive force (the direction of the induced electromotive force is determined by the right-hand rule).

Since the two ends of the rotor conductor are shorted by short-circuit rings, under the action of induced electromotive force, the induced current in the rotor conductor will be basically consistent with the direction of the induced electromotive force. The current-carrying conductor of the rotor is subjected to an electromagnetic force in the stator magnetic field (the direction of the force is determined by the left-hand rule). The electromagnetic force generates an electromagnetic torque on the rotor shaft, which drives the rotor to rotate in the direction of the rotating magnetic field.

Through the above analysis, it can be summarized that the working principle of the motor is: when the three-phase stator winding of the motor (each difference of 120 degrees of electric angle), after the three-phase symmetrical alternating current is introduced, a rotating magnetic field will be generated, and the rotating magnetic field will cut the rotor winding, thereby generating an induced current in the rotor winding** The sub-winding is a closed path), and the current-carrying rotor conductor will generate electromagnetic force under the action of the stator rotating magnetic field, thereby forming an electromagnetic torque on the motor shaft and driving the motor to rotate, And the direction of rotation of the motor is the same as the direction of the rotating magnetic field.

1. The design time is different. Y represents the first modification design of the three-phase asynchronous motor, Y2 represents the second modification design of the three-phase asynchronous motor, and Y3 represents the third modification design of the three-phase asynchronous motor.

2. The protection level of the shell is different. The protection level of the Y series motor is IP44, the shell protection level of the Y2 series motor is IP54, and the basic protection level of the Y3 series motor is IP55.

3. Upgrading. Y2 series motor is a replacement product of Y series motor, Y3 has a big improvement compared with Y2.

On the basis of Y-series motors, the Y2 series motor Bibi has higher efficiency, larger starting torque, improved protection level (IP54), improved insulation grade (F-level, according to B-level assessment), and the appearance of the motor is novel and beautiful, and the structure is more reasonable.

Y3 series motors are based on Y2 series motors using cold-rolled silicon steel sheets, the amount of copper and iron used is slightly lower than that of Y2 series (Y2 series is lower than Y series), fans are different (regardless of size and shape type), the efficiency standard of Y3 series motors is equivalent to the EU EFF2 standard grade, and can reach the export EU level.

Y, Y2, Y3 series three-phase asynchronous motors are common industrial motors, and they have some differences in design and performance.

Y series three-phase asynchronous motor:

It should be noted that the specific selection of which series of motors should be determined according to actual needs. Different series of motors may have differences in power, efficiency, maintenance costs, etc., so they need to be selected according to specific application scenarios and requirements.

In short, you need to determine according to your own needs

The only difference between YX3 motors and YE3 motors is their different efficiency.
