What is the difference between Y, Y2, and Y3 series three-phase asynchronous motors?
1. The design time is different. Y represents the first modification of the three-phase asynchronous motor, Y2 represents the second modification of the three-phase asynchronous motor, and Y3 represents the third modification of the three-phase asynchronous motor.
2, the shell protection level is different. For example, the series motor protection grade is IP44, the Y2 series motor has enclosure protection grade IP54, and the Y3 series motor has basic IP55.
3, update and replace. Y2 series motors are newer generations of Y series motors, and Y3 has a big improvement over Y2.
Y2 series motors are more efficient based on Y series motors, have higher starting torque, improve the degree of protection (IP54), improve the insulation level (F grade, B grade), the appearance of the motor is novel and beautiful, and the structure is more reasonable.
Y3 series motors use cold-rolled silicon steel sheets based on Y2 series motors. However, the amount of iron used for copper is slightly lower than that of the Y2 series (Y2 series is lower than Y series), and the fans are different (regardless of size and shape type), Y3 series motors. The efficiency standard is equivalent to the EU EFF2 standard level and can be exported to the EU level.
