System description and operation

VFD system

A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface.

AC Motor

The AC electric motor used in a VFD system is usually a three-phase induction motor. Some types of single-phase motors can be used, but three-phase motors are usually preferred. Various types of synchronous motors offer advantages in some situations, but three-phase induction motors are suitable for most purposes and are generally the most economical motor choice. Motors that are designed for fixed-speed operation are often used. Elevated-voltage stresses imposed on induction motors that are supplied by VFDs require that such motors be designed for definite-purpose inverter-fed duty in accordance with such requirements as Part 31 of NEMA Standard MG-1.

Q:I know that means i'll choose my job at basic but does it mean that I could get a job I don't want? I really want to do Biomedical Equipment Tech.: It means while in Basic, you will get a list of jobs to choose from, based on your Electronic line score. The jobs offered will be those you qualify for and that have a Tech School class that starts within about two weeks of you graduating Basic. But you have to understand, in the electronics area, Tech school class's do not start every week, or even every month, some only have 4 or 5 Tech School class's each year. So you will NOT be offered every AFSC, only those with a Tech School class that starts soon after you finish Basic. So there is really no way to tell, if Biomedical Equipment Tech will be offered or not.

Q:I'm currently doing a 3 year advanced diploma for electronics engineering program. However, I don't feel it could really lead to much possibilities. What do people think?Are there any electronics engineers here in the room?? If so, what challenges do you face??: It's pretty booming right now, and probably will be for the next couple of decades at least. As far as possibilities go, what are you looking for? Some EE's start their own companies and make millions. It's as much as what you make of things as it is about hopping on the right train to take you where you want to go. The downside of engineering has to be the pressure and the deadlines. Marketing and money drive engineering. And the market doesn't want to wait forever for the next gismo. Your design has to be finished by a certain time or else the whole bridge project gets held up, etc.

Q:Crossword: (5 letters) Fire extinguisher used for electrical equipment. (I believe the 4th letter is E): WATER!!! no? Novec is another one like Halon

Q:I have a garage full of my dad's old equipment from oscilloscopes, amplifiers, circuit board materials, etc. that I don't know what they are/or are worth, or how to go about selling. Does anyone have any suggestions other than listing everything individually (there is a lot) on OKorder or CraigsList? I'm leaning towards hiring someone to come in and auction it all off for me, but need suggestions.Thanks!: Perhaps try an OKorder seller, or let a friend or relative put it on OKorder. It is quite a bit of work to sell on OKorder properly, but if you give then half the proceeds, you both might win! Another approach is to bring it to a large city electronics swap - all kinfds of electronics geeks come to these and you will gets lots of advice on value.

Q:does adjusting the router's position about an inch or adjusting the direction of the antenna affect my laptops browsing speed?: It can indeed. Moreover, adjusting your router position actually increases or decreases your wireless signal. Your wireless signal strength has a large bearing on your browsing speed. However, an inch or two should make little to no difference. But dont rule it out.

Q:Are the different parts of an electrical distribution system connected in series or in parallel? Give the evidence. Give two reasons.: All equipment should get supply voltage same.So we have to connect all in parallel But to complete the circuit, we need Phase and neutral Bulbs, fans, washing machines, fridges are connected in parallel

Q:I hateTummy, supper, baggie, materials, equipment, fix used in making food, supplies, ointment: Hopefully. I have rarely heard this word used correctly. It means in a hopeful manner. The following usage is so incorrect: Hopefully, I'll be picked as the best answer. But people continue to do it, and it makes my ears bleed.

Q:A. Identify only the primary source of electrical energy for the equipment or circuits in question.B. Enable backup energy sources, such as generators and batteriesC. Make sure all workers are safe and accounted for before equipment and circuits are unlocked and turned back onD. Avoid testing equipment and circuitry to ensure they are de-energized: picked B and got it wrong. :( its either D or C

Q:Especially from the U.K? I wanted to buy some weighing scales for like ?6, cos like I noticed you can resell them over here in the U.K for like ?50, or are these fake?: the us is in a recession; NOTHING should be bought from China. also, China is a COMMUNIST nation.
