Problems with Motor 2000 Lincoln Navigator?

ok ! so what,s the problem?

1. Is it true that 4 cylinder car engines should use special motor oil and not the regular type motor oils that?

Complete nonsense and marketing hype. You can use whatever oil you want and as long as you change it regularly the body will fall off the car before the engine wears out. Lubrication related engine failure is almost unheard of

2. A 1.5 kW electrical motor was run on full load for 4 hours. Consider the efficiency of the motor to be 100%,?

A and C A because Energy = Power * Time C because Enthalpy h = Internal energy U PV work

3. What type of jon boat & motor to get?

no smaller than 14 foot. a 20hp motor. a 16 ft. would be safer and more convenient. you cannot get what you need for your price unless you find a used buy

4. how much are motor mount , oil pan and radiator?

country/state? motor size? A/C? turbo? Auto? all factors in the price

5. Can a microwave motor be powered by usb? [closed]

USB power is really quite limited. As well as motors made for your particular application, if you can go to 12 volts you could look at the motors used for rotating reflectors on automobile warning beacons or disco lights.However, USB powered turntables for light loads are available quite cheaply. (Example Amazon link)

6. Life WITHOUT a motor vehicle, possible?

Depends... when I lived in Manhattan the train stations were everywhere... and parking was near to impossible. I had little choice. It was good for me to be more active too

7. DC motor pid control [closed]

I am assuming you mean 12V geared DC motor. It can give a stable response. In fact, this is done all the time. Plus, if the load is relatively stable, and the gears and other transmission elements have enough friction, you may not even need to use PID - a simple proportional controller might be good enough. But your question is not sufficient for providing a specific answer to a particular design option, because you can also implement a PID controller for a 12V geared motor under load and have it not work. It just depends on the specifications of motor, the gears, the power supply, the controller (amp), the software, and the load

8. Why use a variable frequency drive along with an electric motor?

Unlike DC motors, whose speed can be controlled by varying voltage, the speed of certain types of AC driven motors - synchronous motors and induction motors - can only be controlled with a variable frequency drive. Induction motors are very inexpensive and reliable because they have no windings or magnets on the rotor. They rely on currents "induced" in the rotor to produce a magnetic field acting against the field created by the windings in the stator (body) of the motor. The speed an induction motor turns at depends on (1) the frequency of the alternating current (hence, alternating magnetic field) in the stator and (2) the load, or torque demanded of the motor. The only way to control the speed is by adjusting the frequency of the AC current. Variable speed controls make it possible to replace more complicated, expensive and less reliable DC motors in many applications.

9. How does an electric (AC) motor work?

This is a huge question and I do not know how much detail you want or how much you've had the education to understand, so I will be general. First a few basic concepts: Current flowing through a wire causes a magnetic field to be generated. Magnetic fields influence each other to move. Alternating current reverses polarity with each cycle. One simple type of electric motor consists of two fixed magnets and a coil of wire wrapped around a central shaft. The coil of wire becomes an electromagnet when an electric charge is applied to it. This then generates a magnetic field. The coil and the shaft it is attached to begin to rotate due to interactions with the two fixed magnets. This rotating shaft is the basis of the electric motor. There are many more details which you could learn if you want to do more research. There are many more complicated motor designs. An electric generator is the opposite of what was just described--physical rotation causes an output of electric energy. If you want a more detailed understanding of the fundamental forces involved, I would suggest taking an electromagnetic field physics class. Or if you just want to learn more about motors get one and tear it apart! Reverse engineering is the best way to truly understand how something works.

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
