Power Window Motor?

Remove the door panel, remove the plastic, remove the motor

1. How to drive DC motor with stm32?

I would just use a L298 Driver IC. They are pretty simple. I do not like messing with P channel transistors.You should check the datasheet for the appropriate thershold volatages and check what you are actually getting on your circuit

2. I am looking for some advice on motor/motor controller?

Best would be to take an industrial servo drive. It wwould always come with all required software, tools and whatever you may need. The cost may be a little high... But wasted time is minimal

3. Harddrive spindle motor?

maybe you do not have enough?? just a guess

4. What is a breaking arrangement in an electrical motor?

It is an arrangement meant to stop the motor or sometimes used to reduce the speed.In DC motors and AC motors there are different types of breaking.To know more search "Breaking of DC motor" or "Breaking of AC motor" on internet. What is a breaking arrangement in an electrical motor?

5. What does it mean by a 25 kW electrical motor?

What does it mean 0.37 kw on a land pump? Does it mean it consumes .37kw per hour or something else?

6. Diode Sizing for DC Motor H-Bridge

I have not seen a definitive, engineering answer with explanation to this. So this is just a 'Strawman' or 'Aunt Sally' to be knocked down or improved.The 'folklore' agglomerated answer I derived from people with more experience than me was:That all sounds reasonable, but feels unsatisfyingly ad-hoc. So I would like a better answer with the maths, science and engineering too

7. The purpose of microtubules and motor proteins in mitosis?

The spindle fibers that connect to the Kinetochore on the sister chromatids are made of microtubules and are involved in the splitting of the sister chromatids in anaphase. (Kinetochore is a structure of proteins associated with specific section of chromosomal DNA at each centromere.) This is what I took from your question I am sorry if it is not what you are looking for.

8. Does an a/c motor need a capacitor?

wow the simple answer is NOOOOO but if your motor has one, then yes its required to start it...

9. Will putting a fan or propeller on a drill work as a boat motor?

A cordless drill would work, plenty of power - but is pretty heavy as it is made to drill holes primarily.... The chuck is convenient to grip a shaft in though. It would be simpler and and easier to use a small 360 or 540 can motor, a simple mechanical speed control and a rechargeable battery of around 6 volts or so - all this is available from any competent hobby shop, along with various linkages, props and so on. I would suggest using a small boat prop on a shaft drive in the water - rather than an air screw - it is more dangerous to have a large rapidly spinning prop near hair and hands.

10. what's the BEST MOTOR OIL out there

i've tested all the synthetics i can find in my cars and those of a couple of friends. i keep track of fuel economy and oil deterioration. this is what i found. as a general rule, synthetics are better than conventional oil, but not always. generic synthetic and valvoline actually got lower fuel economy than some premium conventional oils. mobile 1 is about equal to a premium conventional oil for power and fuel economy. pennzoil and quaker state synthtics are ok, but you can do better and they wear quickly like a conventional oil. amsoil and royal purple will give amazing spikes in fuel economy and power, but deteriorated faster than anything else i tried. same with the other cars we ran it in. it is an exceptional racing oil where the oil gets changed every 500 miles, perhaps unequaled as a racing oil, but not overly useful as a daily driver because in every car we tried them in economy and power dropped SHARPLY after 1000 miles. Castrol Syntec gave almost as good as the peak gas mileage of amsoil and royal purple, but did not deteriorate like they did. it tends to hold it's condition to close to 6K. now some will come on and say you can run amsoil, royal purple and mobile 1 extended much longer than the others, (up to 20,000 per oil change) but this is what i found when i researched that. repeatedly toyota and honda mechanics i talked to said the only cars they rebuild right now are from people who try to do that. a couple of companies i know that put thousands of miles a month on their cars tried as well. they all ended up with extra rebuilds... do not do it. on 0 weight oils, i tried them as well and found that unless you live in an area where the temperature regularly stays below 0 (farenheit) you can do more harm than good as this does not stay on the motor as well and you end up with some metal on metal at start ups.

IGBT of Fuji Motor Electronic Equipment Technology
The IGBT technology of Fuji motor and electronic equipment technology has been commercialized since 1988 and has been supplied in the market so far. Figure 1-3 shows the development process and application technology of IGBT products from the first generation to the fifth generation. Epitaxial wafers are used in the first to third generation IGBT, and the characteristics are improved by optimizing life cycle control and refinement technology of IGBT. Then, the fourth and fifth generation products have achieved significant characteristic improvement through the transition from epitaxial wafer to FZ (floating zone) wafer. In this regard, the design policy of IGBT has changed greatly compared with the past.Firstly, the basic design idea of IGBT using epitaxial wafer (series products up to 600V of the third to fourth generation, called "breakdown type") is as follows. In order to realize the low-pass state voltage during IGBT conduction, a large number of carriers are injected from the collector side to fill the IGBT with high concentration carriers. In addition, the n-buffer layer specially set to maintain the high voltage forms a very thin n-layer, so as to realize the low-pass state voltage. In order to realize fast exchange, life cycle control technology aiming at the rapid disappearance of carriers filled in IGBT is also adopted (through these, low exchange loss (eoff) can also be realized). However, once the life cycle control technology is applied, even in the normal on state, due to the effect of this technology (the carrier transport efficiency decreases), there is a problem of increasing the on state voltage, which can be solved by further high carrier injection.In short, the basic design concept of IGBT using epitaxial wafer technology can be simply summarized as "high injection and low transmission efficiency". In contrast, IGBTs using FZ wafers (series after the fourth generation 1200V) adopt a reverse basic design to inhibit the injection of carriers from the collector side and improve the transmission efficiency by reducing the injection efficiency. In the above-mentioned design concept of IGBT using epitaxial wafer "high injection and low transmission efficiency", the carriers that are not easy to be injected are forcibly suppressed through the control of life cycle, which not only limits the improvement of characteristics, but also increases the standard deviation of on-state voltage characteristics through the control of life cycle, It is very disadvantageous to the large capacity required for parallel use with increasing requirements in recent years. The technology developed to overcome this problem is a new IGBT using FZ chip (NPT: non punch through (used from the fourth generation IGBT) / FS: field stop (used from the fifth generation IGBT) - IGBT). The IGBT does not adopt life cycle control. Its basic design idea is to control the impurity concentration of the collector (P layer), so as to inhibit the carrier injection efficiency. However, in order to realize the characteristics superior to the IGBT using epitaxial wafer, it is also required to realize more than one hundred for the 1200V high voltage resistant series IGBT μ M (the thickness of n-layer in NPT and fs-igbt using FZ wafer ≈ the thickness of chip (wafer). The thinner the thickness, the lower the on state voltage can be generated). In short, it is not too much to call the development of IGBT using FZ chip a challenge to chip thickness.Fuji electric and electronic equipment technology has solved these problems. Starting from the fourth generation 1200V series - IGBT, it has realized the commercialization of "s series" constructed by FZ chip NPT. In addition, 600V series technology with higher thickness requirements is further developed, and 600v-u2 series (fifth generation) is being commercialized. In addition, in 1200V series - the fifth generation "U Series", in order to improve the performance better than s series, NPT structure has been changed to FS structure.The so-called FS structure does not use the life cycle control technology. While following the basic design concept of "low injection and high transport efficiency" of carriers, an n buffer layer to maintain voltage is set on the FZ wafer, so as to realize the IGBT structure thinner than the NPT structure. Through this change, 1200v-u series realizes the low on state voltage characteristic better than s series, and completes its commercialization. In addition, this technology is also used in 1700V series high voltage withstand series, and is also starting to be commercialized.Figure 1-3 changes of Fuji motor electronic equipment IGBT application technologyIn addition, Fuji electric and electronic equipment technology is also refining the surface structure indispensable for the improvement of IGBT characteristics (IGBT is formed by multiple IGBT plates. Through refinement, the more plates, the more low on-state voltage can be realized). Up to the fourth generation products, the planar structure (the structure of planar IGBT) has been used to promote refinement, so as to improve the characteristics. However, starting from the fifth generation products - 1200 and 1700V series, the grooved IGBT technology slotted on the Si surface and constituting IGBT has broken the subtle technical barrier and achieved unprecedented characteristic improvement. Figure 1-4 shows the change of characteristic improvement of 1200V series.Figure 1-4 improvement of balance characteristics
