Q:When I put freon in ac motor runs for 1 to 2 seconds

The connections for R-12 and R-134a are different so if your A/C equipment was able to connect it's R-134a fittings to the car then I would say that someone has already changed the car over. On my car I changed the fittings, added new compressor oil and then had it vacuumed out before adding the new R-134a. It works marginal but I don't think you can ever get them to work as good as the R12 did.

Q:blower does not come on with switch and fuse is good.

Should be in the right rear quarter area

Q:I am converting my '79 VW rabbit from ac to non-ac.Where do I find the bracket that holds the alternator low on the block.

Check first with the auto-parts dept.at the dealership. They are fairly knowledgeable as to whether that is possible. Otherwise ask the service manager if that is possible to do. They may have a parts car out back of the dealership and you could get a used bracket there. Otherwise check out autosalvage yards for a 79 non ac car for the bracket.

Q:Hi all, I have a AC motor that i would like to use to make a wind generator. I would like to know if I can make this motor to DC. If anyone has done this an was successful, please show me how.

Not really, get yourself a permanent magnet motor. To convert an AC motor to DC would require a major rework of the motor.

Q:a motor that runs on ac and dc?

Mostly, if they have a lot of power in a small package (especially for rotary speed), but are used only sporadically. They often are a bit noisy. If they have a speed control, then they could be universal.

Q:Preferably an ev gray design

1 HP = 745.699872 watts so for at 65HP you will need 48,425 watts that is a lot of electricity. 1 watt =1 Amp x 1 volt. At 110 volts that is about 440 Amp more than enough to kill someone so please be careful.

Q:Can I inverse rotation to AC single phase motor? How?

Motor that can be reversed have wired connections that have to be changed to do so. You could bring the wires out to a relay or switch. There is no way to do it by playing games with the power phasing, etc.

Q:i purchased one grass cutting electric blade trimmer (sun-jeo) from USA .4.5amp motor -120volt-60hz. how much its watts and it can be use in 240volt-50hz in india?how much of rpm the motor will produced while operating?

that depends on the motor the gearing and everything is different in every motor you must check the specifications of the motor you choose ... the power of the motor will be approx 120 volts * 4.5 approx = 490 watts a fairly low power motor.. and no unless you can divide your 240 in half with a center tapped transformer isolating one maybe then you would be able to use it but would require a special device to down the voltage to 120 you cannot run it at 240 wihout completely destroying it..

Q:Specifically, I want two questions answered:1.How does a single-phase permanent split capacitor AC induction motor work? (I know it involves the phase difference between a capacitor's current and voltage, but I need some more detail).2. All the fans in my house with this type of motor have 3 speeds. How do they achieve these three speeds? I've taken apart the motors and found 4 pairs of coils (i.e. 8 coils in total)?

Re added details: If there is no resistor inside, there must be voltage taps on the windings. I think that is the most common arrangement for a lot of types of fans.

Q:AC motors are designed to operate at +/- ____ Percent of their rated potential difference, and +/- _____ percent of their rated frequency?

To approach the question the way it is asked would be to say few. Only synchronous A/C motors operate at a fixed speed based on the number of poles and the frequency of the power supply. A synchronous speed can be in increments of 3600 RPM or 2500 RPM depending on the frequency. Induction A/C motors will operate at the synchronous speed when there is no applied load and will begin to slow down slightly as load is applied. That slip is usually around 2- 3% when the nominal design horsepower is produced. . For example, an 1800 RPM synchronous motor will operate at 1800 RPM when fully loaded. A common induction motor will operate between 1800 and 1750 RPM. Most motors are manufactured to specific horsepower ratings at their design speeds and so cataloged. When a device needs a motor and it's design horsepower is known, the motor selected will be the next larger size. For instance a direct drive pump may be rated at 17.5 horsepower non-overloading (maximum) at 1750 RPM. There are no standard motors made to that specific horsepower so a 20 horsepower motor will be selected and will run efficiently at that partial load. Depending on the motor cooling system and the motor wiring insulation design, some will have transient service factors of 10-15% above the full load rating, but prolonged operation in an overloaded condition will shorten the motor life. In the larger sizes, motors can be custom built to closely match a non-standard horsepower within the normal speed range.
