IE4 Low Voltage 3-Phase AC Induction Motor
The IE4 ultra-high efficiency low voltage three-phase asynchronous motor designed and produced by our company absorbs advanced domestic and foreign technologies and combines the advantages of similar products. It has the characteristics of high efficiency and energy saving, stable operation, low vibration, and good starting performance. The motor adopts F-class insulation, and the temperature rise of the whole series is assessed according to B-class. The junction box, base, and end cover are beautiful and generous in shape and are conducive to noise reduction and ventilation, which greatly improves safety and reliability.
The frame size of IE4 series three-phase asynchronous motors ranges from 80 to 355 (mm). The main terminal box is a sealed structure with the same protection level as the motor. It is generally installed on the top of the motor frame. Depending on the specific purpose, the wires can also be connected to the left and right sides. There is a separate grounding terminal in the terminal box to meet the different wire requirements of users.
IE4 ultra-high efficiency three-phase asynchronous motors are widely used in machinery without special requirements, such as food machinery, agricultural machinery, air compressors, ventilators, industrial water pumps, cutting machine tools, transportation machinery and other general equipment. They are used as prime movers in various industrial and mining enterprises such as mines, petrochemical industries, power plants, etc. to drive blowers, coal mills, rolling mills, winches, crushers, belt conveyors and other mechanical equipment with large rotational inertia.

Key Points You Need To Know About the High Voltage AC Induction Motor

CHAPTER ONE
What is IE4 Motor energy efficiency level?
At present, more than ten countries and regions in the world have issued motor energy efficiency standards.
The motor energy efficiency standards are constantly improving, and the trend of motor standardization is obvious.
The Electrical Engineering Committee IEC has unified the global motor energy efficiency standards into four levels: IE1, IE2, IE3, and IE4, with IE1 as standard efficiency, IE2 as high efficiency, and IE3 as ultra-high efficiency, and published their standard values.
In 2014, the IEC organization published IEC 60034-30-1, expanding the motor power range to include motors from 0.12KW to 1000KW, and officially published the IE4 energy efficiency standard value.
The increase in energy efficiency classes is mainly achieved with asynchronous technology by using more active material.
With each increase in efficiency, the length and, if necessary, the size of the motor frame changes.
To avoid jumps in motor size, there are various optimization options, such as increasing the slot filling by adjusting the winding, using higher-quality electrical layers and, if necessary, using copper as the cage rotor material.
The figure shows the power-dependent efficiency curves for IE2 to IE4 motors within the scope of Regulation (EU) 2019/1781.
Exceptions to the classification requirements of IEC 60034-30-1
Operating modes S2, S3<80 %, S4 to S10
Inverter-driven motors that cannot be operated directly from the mains.
Motors that cannot be measured independently, such as pump motors with wet rotors.

CHAPTER TWO
How does energy efficiency rating affect operating costs?
Do you want to save cost for your industrial application?
Understanding the specific needs of your application, such as load requirements and operating frequency, is key to selecting the most energy-efficient motor
CHAPTER THREE
How to choose the right electric AC motor
Electric motors allow different types of movement: fast, precise, continuous, with or without shifting…
All these applications require their own motor technology.
There are three main families of electric motors to choose from:
AC asynchronous motors (single or three phase).
Synchronous motors : DC motors,
brushless motors.
Stepper motors
Then you need to determine the type of application, as this is the key that guides the choice of motor among these three families.
If you want your motor to run continuously, with little speed variation, choose an asynchronous motor.
For dynamic applications, a synchronous motor is the right choice.
Finally, for precise positioning, choose a stepper motor.
Depending on the required movement, you also need to determine the technical specifications and dimensions of the motor.
For the technical specifications, it is also necessary to determine the power, torque and speed of the motor.
For the selection, attention should be paid to the footprint (the size of the motor) and the type of mounting (how the motor is fixed in the system).
The choice of the size and strength characteristics of the motor also depends on the industrial environment in which the motor is located.
There is a construction suitable for any type of special environment (explosive, humid, corrosive environment, high temperature…).
For harsh environments, there are motors with reinforced, sealed, impact-resistant or dirt-resistant housings.
In recent years, energy efficiency has become an important criterion when selecting electric motors.
A motor that uses less energy will have a lower energy impact, thus reducing energy costs.
