WebJun 29, 2024 · So design engineers (and motor end users) must find ways to maximize motor torque while avoiding motor overheating. One industry approach is to set the drive to give the motor its rated current. Doing that will make the motor hot but not too hot. It’s normal for step motor temperatures to reach 70°, 80°, or even 90°C. WebAug 8, 2024 · Re: VVVF Drive overheats Dynamic Braking Resistors. 06/03/2008 11:29 PM. I don't think the fuses are a bad idea, I just don't like the idea of "solving" a problem with fuses. Like I said, fuses should be the LAST resort in a circuit, not a limiting device. Many more sophisticated VFDs use a thermal monitoring algorithm for the DB resistors.
