(1) High efficiency, IE2 is 3% higher than IE1, and IE3 is about 5% higher than IE1.

(2) More high-quality materials are required. For example, IE2 costs 25% to 30% more than IE1 motors, and IE3 costs 40% to 60% more than IE1 motors.

(3) Due to the lower operating temperature, the motor has a longer life and can reduce maintenance costs.
