Reduce the noise of permanent magnet speed control
Thread Content
In permanent magnet speed control systems, the high rotation speeds cause the cooling fins to cut through the air, resulting in significant noise. How can this noise be reduced, or what kind of sound-insulating measures can be used to address it? ?
That’s indeed the case, especially with 3000prm permanent magnet products. We are currently working together with some design institutes in China to address such issues. Thank you for raising this question; if possible, let’s work together to solve it!
