## FAQ
Q: What is the difference between IE2, IE3, and IE4?
A: IE2 is standard efficiency, IE3 is premium efficiency (mandatory in EU since 2021), and IE4 is super premium. IE4 motors offer 10-15% lower energy consumption compared to IE2.
Q: Can the motor run on 60Hz power?
A: Yes. Motors rated for 50Hz can generally run on 60Hz with approximately 20% higher speed and power. Please specify your power supply when ordering for optimal winding configuration.
