Siemens High Low Voltage AC Motor

Q:AC Repair person said I have oil leaking from fan motor and should have replaced. Even though it still works. Show me how hot it got.: Sounds fishy to me. Ha. They are supposed to get hot and there's hardly any oil in a blower motor so you wouldn't see any leaks. A tech can test the amps and the volts. He can spin the fan to see if it spins freely. Listen if the bearings grind when it runs. Test the shaft for play. If he does all that, then he can say if it needs to be replaced. So, I doubt you need one.

Q:Im tryin to do a little home experiment. I want to know the detailed steps to turn an ac or dc motor into a power producing generator. I dont wanna pay for info so any links to free websites with details on this subject would be appreciated. Nothing complex explaining voltage and stuff like that just the actual pieces i need to add replace or remove for power production. thanx: Ac Motor Generator

Q:Is there currently a car that uses DC current Traction Motors, for the wheels, and a generator for power? Railroad engines use this method, on a much larger scale, of course, but has this been considered and used for automobiles?: The full hybrids that can move under electrical power alone (Toyota, Ford, Lexus and Nissan hybrids) use 3-phase AC motors. One of the reasons is that AC motors don't have commutators so they tend not to wear out as often as DC motors. These hybrids have inverters that can convert the hybrid battery's DC current to AC for use with the motors or vice versa when the motors are being used as generators during regenerative braking or being cranked by the gasoline engine to charge the battery. Railroads have been moving to AC traction in the past 10 years as well.. These days on the Class-I railroads the majority of 6-axle diesel-electric locomotives are AC, like the SD70ACE locomotives from Electromotive and the ES44AC Gevo from General Electric.

Q:the pulley isnt seized.it smokes only when ac or defroster is on.i would like to know how long can i drive it with the ac or defroster off all the time.: you can run as long as you like. Just leave the ac or heater off and your good to go.

Q:Why is DC motor wider than AC motor? High speed regulation accuracy? How do you know?: The speed regulation of DC motor usually depends on changing the voltage at the two ends of the armature. The speed and voltage are basically linear, so the speed regulation accuracy is high. However, due to the brush limit, the DC power is generally not largeThe speed change of an AC motor depends on changing the pole number or changing the frequency, while the mechanical characteristic is related to the rotor resistance, armature current and so on. The ancient and lower precision, to achieve servo control should be introduced into the closed loop control system.

Q:one word answer?: You might have bigger fish to fry before to long-- you're probably going to lose your intake manifold gaskets sometime down the road. There was a TSB issued on this problem in earlier models (and I believe the 2004 as well), and thousands of people have been having costly repairs that GM won't cover even though they've known of the problem for some time. It has to do with the Dexcool coolant they put in there (long life coolant) which has somehow been attacking the gasket, leading to a leak-- possibly an internal leak where the coolant gets into your oil and creates the potential for a very bad condition called hydrolock. Further, GM may void your warranty if you flush and oil-change all that stuff out and replace it with the green classic antifreeze.Watch for dropping coolant levels even if you don't see any drips and have that engine checked and replace the gaskets with Felpro replacements. Suggestion-- get thee away from the GM. I threw in some Bars Leak and stuck a FOR SALE sign on mine. Cheap, dirty repair? Dang skippy. I'm not wasting a plug nickel on the thang. That's GM's baby. Nissan is much better and they stand behind their cars. GM needs to stand in front of theirs.

Q:i am working on project and i have 3-Phase AC induction motors with the following specificationsstandard voltage 230vFrequency 60 Hertzhow can i increase the RPM of the motor if i have generator produces 230v and has 150 amp?and how can i know what is the frequency that the generator produces?: What is the HP of the motors? The frequency of the generator should be marked on it. If not, use an oscilloscope to look at one of the output phases; carefully. The generator must be a 3 phase generator to run the 3 phase motors. There will be 3 hot wires, and a neutral and a ground. The neutral may be missing if this is a delta connection. edit: looking at your last question, it appears that this generator is actually an auto alternator, which will not generate any fixed frequency AC, and will not generate 230 volts. Certainly not 35000 watts! .

Q:please answer with construction idea.: A universal motor is similar to a DC motor with the armature connected in series with the field. If DC is supplied it works like any DC series motor. If AC is supplied, the stator and rotor field strengths will vary exactly in phase with each other. When the AC current changes direction, the stator and rotor fields will reverse at the exact same instant. Therefore, the torque will always be in the same direction even though the fields change direction because the stator and rotor fields always have the same relationship with each other. When connected to AC, torque magnitude pulses at twice the line frequency. Comparing operation at a given AC RMS voltage and an equal DC voltage, the torque at any given speed is lower for AC operation. That is due the higher impedance with AC and magnetic saturation at the peaks of the AC waveform. To avoid overheating due to eddy-current losses, series motors intended for use as universal motors are constructed with laminated stator and rotor cores.

Q:How to change AC motor to generator?: The motor can be changed, or diesel gasoline engine as power drive, and capacitor connected to the motor at the outlet of the can, the capacitor adopts non polarity capacitor voltage, then Y must be greater than or equal to 250V, the delta connection pressure is greater than or equal to 400V. conditions must have left the rotor when the rotor magnetic remanence, no. With 6V DC motor in the three-phase one electrically connected to a few minutes, the rotor will produce remanence. Its efficiency is very low, three-phase motor with 4 poles. The speed is 3000 rpm. The maximum is 75%. after the transformation can only be used as emergency power. Do not try, there is not much sense, but can be used as academic discussion. The basic will not be adopted, too much waste, and here is the capacitor capacity at the discussion

Q:Is it possible to run an AC motor off DC current and still have it function correctly?: if it is a universal motor (has brushes) yes. if it is an induction motor, no
