If I have a bunsen-burner fed by a hydrogen gas source, how do I make sure that I don't get a flashback to my source?
Also, can anybody tell me or point me to a good reference describing how to size a pressure relief valve?
I am trying to figure out if I should calculate the MTBF of my new product using 217 or SR-332. I have read all the high level information on the differences between the two and I have experience performing the calculation using the MIL217 method. Can anyone tell me some more detailed...
All decent VFDs have current limiting to ensure that the inverter doesn't blow itself up, therefore I am not worried about blowing any rectifiers up either(as per dpc's comment).
Most VFDs are rated for a temporary starting overload of 200% of rated. This is for start-up since it resembles a...
I have a 100HP/460V synchronous motor sitting in the back of my shop along with a 40HP/460V VFD. I am hoping to hook the two parts together. The motor will be very lightly loaded with a gear box. The only thing I am concerned about is actually starting from 0RPM (kind of like a locked rotor...
visunaik,
There are a set of assumptions that I must make to provide you any information on this matter. If any of these assumptions are incorrect, please reply to this post.
-The form factor of 70X70X140 is a measurement in millimeters.
-Since a switch-mode power supply can be both a...
I was hoping that I could get any information/comments that my colleagues at Eng-Tips may care to voice. I have been investigating SR motors (Switched Reluctance) and have been itching to play with one. I have many articles/papers/books on the control of these motors (as well as other electric...
I've got to design a control for a brushless DC motor and I'm looking for control chips to build from. To give an idea of what I'm looking for, Fairchild Semiconductor made a part that would've been just about perfect...the ML4426 BLDC motor controller. The specifics were the bi-directional...
One great motor type is a winch motor...these motors are easily available from army surplus stores(Princess Auto here in Canada). Some even come with a gear reduction assembly built-in. These motors are certainly powerful enough to do this job in a satisfactory amount of time and they are also...
