The common classification of energy efficiency levels for electric motors is as follows:
The International Electrotechnical Commission (IEC) energy efficiency levels are divided into five levels: IE1, IE2, IE3, IE4, and IE5. IE1 is the standard energy efficiency; IE2 stands for high energy efficiency; IE3 is of high quality and efficiency; IE4 is highly efficient; IE5 is a high efficiency level, representing the current high level of motor energy efficiency.

A very clear collection of motor principles, easy to understand in one article
Electric motor (commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery.

What are the characteristics of winding faults in three-phase motors when there is a phase loss?
When there is a phase loss problem in the motor winding, it is often accompanied by the fact that the phase to phase insulation and ground insulation are burned out at the same time. However, for relatively large motors, necessary monitoring and protection measures (such as differential protection) are often taken. When the motor voltage or current is unbalanced, the protection device will promptly cut off the power supply, effectively protecting the safety of the motor winding.
