Can We Run a Hover Craft with a Single Motor???

With enough thrust, a brick can fly

1. home central ac unit motor seized up, fan doesn't run, top of ac getting hot.?

This is not a cost-saving moment. The motor has badly overheated, This was likely caused bty bearing problems, but it does not really matter bacaue you cannot repair it and continuing to try will increase risk of fire. One option only: replace it. If it is a belt-drive unit, you may be able to do it yourself. If it is integrated, professional service isrecommended.

2. Boat motor will Raise but will not Lower. Please Help?

Check the voltage at the solenoid as it can click but wo not Transfer voltage to run the motor

3. How do I remove hard to get to head cylinder bolts on the mustang motor 97 gt ?

the main reason for torquing down a cylinder head is so as that it particularly is pulled down the two over its finished section and would not enable it to warp whilst it gets warm.only slacken em off and commencing on the centre and shifting out in a spiral take em all the way down to 30 nm then commence on the centre returned and turn em ninety stages then repeat.circulate away 2 minutes between each and each circuit to permit the gasket to "relax". do no longer slacken only one at a time and then re-torque because of the fact the pinnacle gasket is not waiting to realign itself if all something of the bolts are tight and do it whilst the engine is stone chilly.the clarification they replace stretch bolts is to give up them bottoming contained in the block bolt holes and that they could ought to stretch some to try this.notwithstanding it constructive as hell makes somebody countless funds.

4. Is it safe to keep a small bottle of motor oil in your car for the event of an emergency?

yea. people have been doing that for many decades. people that own cars that use up oil carry oil with them so they do not run their oil level too low and break down

5. Are the 3 wheeled motor cycles (Trikes), safer than the 2 wheeled ones?

Not really. The trike is much MUCH easier to FLIP

6. How long will my trolling motor last?

I suggest getting a vmax battery, it will last you a lot longer than after market batteries. wal-mart's batteries die out very quickly because they do not use lead inside. it's all loose and un-condensed so they normally die quickly.

7. how to generate electricity from a small motor that is used in toy cars?

Small Toy Motor

8. What happens when a brush-less motor stalls?

Your equipment will be fine as long as the stall periods are not too big(like 5 minutes). I think the first thing to fail is the ESC as you are using half the voltage the motor is rated for. You also have to take into account that the battery can also heat up and fail, as if you would short circuit the battery. But as I said, if it's not for long periods of time you wo not have a problem

9. How do I change the direction on my trolling motor so I can run it off the back of my boat?

Dependant on the style, Make, and Model of the Motor, it is just as simple as Turning the Control head. To do this, Look at the Shaft where it intersects from the control head. Usually on the Back side (side opposite of the handle) there is a hole with a Grub or lock screw. Sometimes they require a Hex Key to be able to Loosen this. There may also be more than one. Loosen, but try not to remove the screw. Turn the Head till the Handle is in the Front of the Motor Bobbin. Tighten the screw and you are set. .. IF its a Bow Mount trolling motor, thats a Totaly Diffrent story. a bow mount is on a Special Mounting that allows the Motor to be pulled out of the water and lay's flat on the boats gunnels. There would be a way to mount it back there if it is bowmount, but that is a Case by Base basis Based on the Thickness of your Transom and such. I hope this helps!.

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
