Reference Table for Level 2 and Level 3 Energy Efficiency Motors

The difference between a second level energy-efficient motor and a third level energy-efficient motor: There is no difference in motor structure, they are the same. The difference between second and third level energy-efficient motors lies in the different machining precision of key mechanical components, which ultimately results in different working efficiency of the motor. The copper core wire material and wire diameter used in the winding are also different. The working efficiency of motors with second level energy efficiency is higher than the theoretical value of motors with third level energy efficiency.
