Q:The direction of the flow in the pump with DC/AC motor?
what is your question? It turns the same way the motor turns.
Q:does a 3 phase ac electric motor used as a generator create 3 phase ac power?
Yes
Q:we are having slipring induction motor for crane application using rotor resistances for their torque. suppose i use drives for these motors what should i have to do for rotor resistances. please give me a proper solution
This is common on crane upgrades to short out the rotor and use a drive. There are specific drives for cranes but I have never seen a specific drive for a wound rotor motor. The standard crane drive is used. You may have a concern about the motors if they have not been rewound recently since voltage spike from the drive may damage insulation of anything lower than class F. Most re-winders use class H.
Q:It uses deepers for soft starting
To control motor speed.
Q:HiI was interested in the idea of using an electric motor as a kind of long lasting flywheel. It would generate electricity as a dynamo and store this in a battery. The electricity produced would then be supplied back to the motor to turn it. I know there would be efficiency problems but what else would stop this design. It's just I've never heard of a motor being applied as both a motor and dynamo (except perhaps in a hydroelectric dam) and wondered if this might be a problemThanks to anyone who can give some insight!
Any AC motor could not generate electricity ! It is a waste of time effort .
Q:im trying to get two compressors to work of a single pressure switch?thanks a lot!
Assuming both these compressors are supplying the same reservoir, you can use a common pressure switch. But starting current will be well in excess of your 30A. contacts. A better way would be to have the pressure switch supply a heavier current rated contactor, and use the contactor to switch the motors.
Q:The pack is 12v and I really don't have any experience with electrical engines, only gas.
Fisher-Price battery packs are a disappointment to many Fisher Price, riding toy owners. You are probably better off considering a motorcycle, car, or deep cycle marine battery. This does bring up a set of issues that electric vehicle makers have in general: cost, weight, volume/space, and bracketing for the batteries required. The next set of issues relate to charging systems; you might want to visit a couple of automotive and RV shops to get an idea of the considerations involved in selecting a charging system of which cost is only one. It also sounds like it is time to learn more about electricty, physics, and electrical motors. I'm sure that there is a reasonable amount of information available for free on the internet. But, the library is a great source for free information too.
Q:Ok I belive this to be two seperate issues, but they just started in the last week. I have 2004 Saturn Ion that when it runs idle and the AC is off it seems normal. However when I turn the AC on, and when I hear the AC mortor/Compressor start up, the car revs up to about 1500 RPM and then comes back down. Any ideas on what it might be?Second issue started today. The car began to overheat, it almost got to the red gauge then came back down to middle as i was driving. When i got it home, I checked the engine, and the coolant resevoir is full, the oil is good because i recently changed the oil 3 days ago. I let it cool down and started it up again, and it started to climb again, but it did not get all the way to the top, it fluctuated between 3/4 and middle slowly. I noticed that the radiator fan did not kick on once, and i checked the top and bottom hoses running to the radiator. They were both hot. Any ideas?

The AC take a kick to get it going. The engine compensates for it by giving it a little more horse power. once running it does not take much to keep it going. Second issue started today.

I noticed that the radiator fan did not kick on once, and i checked the top and bottom hoses running to the radiator. They were both hot. Any ideas? ANSWER All cars do this. It takes the car to heat up to the thermostat temp. before it opens. once opened the car temp comes down to about 175 - 190 degrees. But it does take about 200 - 210 degrees to open the thermostat. You just never noticed it before.
Q:how do electric motors work on the ff. devices and machines?
effency of any machine , input output work.input energy
Q:Why is the AC motor connected to the capacitor?
The capacitor is used for phase separation, to make the current phase two Rao group produced in the nearly 90 of the difference in eve joy to produce a rotating magnetic field. In three-phase electric current, the current between each phase has phase difference itself, do not divide phase. A capacitor induction motor has two windings, that is, the starting winding and the running winding. The two windings are 90 degrees apart in space. At the start of a series of winding capacitor is larger, when the running winding and start winding through the single alternating current, because the capacitor current of the starting winding in time than the current running winding advance angle of 90 degrees, the first to reach the maximum. Two of the same pulse magnetic field is formed in time and space, so that a rotating magnetic field produces the air gap between the stator and the rotor, the rotating magnetic field, the induced current in the rotor current, and rotating magnetic field interact to produce electromagnetic torque, the motor rotation.
