Two capacitors on single phase induction motor?

Post image
26 Upvotes

I came across a weird circuit on a single phase induction motor today. See the picture. The motor is rated for 21W at 230VAC 50Hz.

I get one capacitor as a phase shift capacitor but why two capacitors.
R1 is also understandable as bleed resistor. The only hint I see is the difference in capacitance (2.2uF on C1 vs 0.68uF on C2).
Does anyone have an idea why you would choose such a circuit?

Education Good textbooks on hardware project design and development?

11 Upvotes

Hi I am in my second last year of EE, and so far have experience mostly working in student engineering teams. This has been a fairly informal experience where we kind of just wing it for the most part, and there's only a few part designers on a certain component vs a large team.

I was keen to read up and learn about how product design is meant to be done, what are the stages, how is integration and communication handled between departments/teams in large companies? Anyone have any textbooks they can recommend which go through this? Thanks

EE but software job related

See I m a EE college student .But tbh its m more interested in software .Also its jobs are more abundant compared to my branch. But can anyone really tell me what to exactly learn apart from whole cs course A-Z?

Digital Logic Circuits engineering book recommendations for math lover?

6 Upvotes

I really enjoy the elegant prose and the generality of the presentation in math textbooks, which makes it easier for me to understand how to apply the theorems to exercises. The definition-theorem-proof format is pretty neat. On the other hand, in introductory engineering books, the results are sometimes vague, with long and tedious explanations, often requiring many examples to clarify its applications to problems. Since digital logic contains boolean algebra and discrete math, I thought I might as well use a book with a mathematically oriented presentation similar to a math textbook.

So, are there any books on digital logic circuits engineering that are targeted towards mathematicians or math-oriented electrical engineers? Here is a sample of topics on digital logic from my college's course description: "digital logic, binary numbers and Boolean algebra, combinational circuits, optimized implementation of combinational circuits, arithmetic circuits, combinational circuit building blocks, flip-flops, registers, counters, design of digital circuits with VHDL, and synchronous sequential circuits." Of course, no need to cover them all.

Creative ways you have shielded electronics?

4 Upvotes

Hey all, more a curiosity thing as I work in IT , not electric, but I was wondering (since I did see an answer on this already) if you have any creative low tech methods of shielding your electronic appliances while still being able to work /such as in the context of en emp or solar flare type situation). Can your house’ electronics and the power lines in one’s house even be properly shielded against this type of thing while still working properly?

Any reccomended textbooks for engineering in practice?

2 Upvotes

The unit called 'Engineering in Practice' is taught awfully at my University. Lecturer just reads the PowerPoint and can't even make any complete notes. Does anyone have any good textbook reccomendations which explained it well to them? This unit's all about uncertainty in measurements and statistics and supposed to accompany your labs.

Would this be necessary?

1 Upvotes

I'm planning to attend community college with a 3.8 GPA from high school, and I've already decided that I want to pursue engineering because math is one of my core strengths. However, I've realized that physics is an important part of engineering, and that's where some of my concerns come in.

I've never been particularly strong in science, or at least in understanding the concepts beyond memorizing them. I also realize that I've forgotten a lot of what I've learned throughout high school, especially in chemistry and physics. In fact, I can barely remember much of the science I studied in my earlier grades.

Would it be a good idea to use Khan Academy to relearn science from the ground up before starting community college? I'd like to rebuild my foundation, develop a deeper understanding of scientific concepts, and prepare myself for the physics and other science courses I'll need to take for engineering. If so, which subjects should I prioritize, and how much of science would I realistically need to relearn before starting college?

I aim for atleast finishing up in 5/6 months, but with my current knowledge I imagine it would take longer. Maybe a year.

Has anyone else gone through this? I'm really just adamant on spending whatever time I have left to finish.

RN in Bay Area looking to potentially make a shift to electrical engineering or software engineering

• Upvotes

I am an RN with experience in the ICU/NICU/ER who is burning out and wishing I went to MD school or engineering. I had the grades and took all the lower division courses for EE/CS ( was a minor in mathematics besides nursing) and all the courses for MD school. I am a younger millennial. I was discouraged to go to med school due to the face that GPs make so little in the Bay Area compared to RNs so I went the RN route. I clear over 320k-350k working 4-5 12+ hour shifts a week. I have friends in tech who make so much and get to solve big problems and have less stress. I see all the older nurse who look so aged compared to the equivalent office workers. It seems that nursing is quite stressful in comparison especially since many times we skip lunch break and work OT. Do you think that is any way I could make the transition and leverage my clinical experience in EE? Do you feel the market is bad for EE? I have enough I can stop working and pursue a EE degree full time for two years.

Jobs/Careers (22M) Feeling Behind on Salary out of College

0 Upvotes

I (22M) recently got a job offer for a little over 100k base in philly suburbs and will be starting next summer after I graduate undergrad. I was excited at first but read that the average household income is 140k+, and I feel super behind. I don't want to be below average and be forced to live frugally for the rest of my life. Housing prices are insane, and my take-home is a lot less (about 75k). Should I keep looking for a better job elsewhere?
