- Q: I looked up blower motors for my 99 Jeep Grand Cherokee online and they have a few VERY different ones:Crown Left Blower Motor, Dorman AC blower motor, etc. Is there not just ONE blower motor? How do I best go about purchasing these correct parts online without having to shell out so much dough?!
- Try switching your wall thermostat fan switch to the on position. That is suppose to make your fan run 24/7. If it starts then your stat is not always making the connection in the auto position, and you need a new stat. If it still won't work, remove the cover of your furnace and trying spinning the motor by hand(w/ switch back in on). If it starts then you either have a dead spot in your motor windings, or a bad motor start capactior. If the motor is old your better off just replacing both. Unfortunately you can't go and get a motor just anywhere, but you can get a stat at a hardware store. If you need a motor check on the furnace manufacure's website for a parts dealer in your area.
- Q: I'm interested in learning what happens to a three phase motor if one phase loses power 1) while running, 2) prior to start?I've I've got a three phase motor with only two phases still good, can I manually rotate it to give it a quot;kick startquot; so it will continue to run in two phases?
- In case it's a Delta wound Motor the current going through each phase will exceed the designed current.It willcontinue to run for some time as the rotating magnetic field will still be produced and then one phase will blow and the motor will stop.This will be true for case 1 and 2 both. In case it is a Star wound motor the rotating magnetic field will no longer be produced and the motor will not run.True for 1 and 2 both. You can't give it a kick start to run.Thats true only for single phase motors which either need a manual starting torque or a capacitor toprovide it.
- Q: We rewound an ac motor but when we tested it,in a jog, one of the coil got burnt. We checked if there was a wrong connection but there was none. We checked also the number of turns,the size of wìre. We rewound the burnt coil,and test again,the same thing happened.We're wondering why it was happened?.Please help. . .
- The basic reason is too much current, so need to find the cause of that. I have had experience with a motor that drew far too much current on no load, and continually burned out, and it turned out the field lamination were skewed so that the field was not properly aligned magnetically. This did not cause poling, but the problem was visible when the field was inspected. This was a manufacturing defect. Other reasons may be shorted turns, or the laminations are not well insulated, as each is supposed to be insulated from the next. I expect you have already checked for poling and that the shaft does not have excess play. I don't know what the effects of a bad rotor are. I guess the winding causing the problem can be tested and compared with others on the bench, without the rotor. Apply a low voltage from a transformer to the winding and measure the current, comparing with other identical windings. When you say tested in a jog: To me jogging is pulsing the motor to step it along a bit. Could this be grossly exceeding the current rating? I guess a particular coil would tend to burn out first, but the others would be hot too. In the end the rated current should not be exceeded for more than a few seconds, then wait for it to cool down. Some larger motors have starters that prevent the restart until it has cooled down. It is also possible that a supply phase is bad, possibly due to a faulty contactor or connection that has high resistance..
- Q: Will a DC shunt motor operated on an AC supply?
- NO..it will run based on your country voltage for example in my country it will run 50Hz..that means it will change direction(clockwise-counterclockwise) in 0.02 second..U can't figure it because the movement is so fast.
- Q: blower does not come on with switch and fuse is good.
- Should be in the right rear quarter area
- Q: I installed a new blower motor resistor pack on my 97 Dodge B2500 Van. The pack and connecting harness had burnt from a faulty connection. I chose to use one from a 98 1500 Pickup as that I could not find a wiring harness for my van's resistor pack (No salvage yard had a 97 or latter van). The old resistor pack was the open coil type, the new pack it the solid ceramic type. I installed the pack and harness on Saturday. I located the pack (when standing in front of the van) on the left side of the cover over the evaporator. core. Yesterday and today the blower motor quit running when I was adjusting the fan speed. The AC compressor was still running. Shut the control off and back on a few times and the fan works, it seemed to take about 30 seconds to one minute to restart. It will work at any speed. It only quits when I change fan speed and at random at that.
- you may need to replace the actual switch that turns it on ,i have seen a lot of those go bad and that's how they,ll do if it had anything to do with the resistor again it wouldn't work at all or it would have burnt the new resistor out on it,so you know that part of it is still working, id lean towards the switch ,it could have been part of the problem all along ,id try another switch on it,see if that doesn't repair it,you could also have motor going out on that one that will cause them to burn up resistors a lot,good luck.
- Q: The Tesla Roadster is powered by this motor. What is the meaning of i?
- You need to specify what type of motor you have. There are two basic types: DC - is it a shunt motor or a series wound motor? a resistor can be used for speed control of both of these but the characteristics are different for each. AC - is it single or 3 phase? the only type of ac induction motor that can use a resistor for speed control is a wound rotor type. For standard induction motors you need an electronic device that varies the frequency, but bear in mind that the power output will be less at lower speeds for the same supply voltage.
- Q: hey i have four questions for yas most apprieciated if you can help!!!Question 1Where does the energy that makes the DC electric motor work originally come from?Question 2What difficulties would you have measuring the current flowing through a DC electric motor when it is operating?Question 3Please Explain how you would calculate the resistance (in ohms) of a DC electric motor circuit.Question 4PLease name as many appliances that have electric motors in themplease and thank-you if ya answered!!! PEACE OUT :D
- 1. The power for a DC motor can be from different sources. It may come from a battery such as small toy trucks or the blower motor on your car. It may come from AC power through rectification. Such as in many industrial applications. 2. It is done commonly in troubleshooting. I personally would use a clamp on ammeter. Simply put it around one of the wires going to the motor and read the readout on the meter. Smaller motors this would be harder. You could also use a regular ammeter by placing the ammeter in series with the motor but that would require some wiring. 3. To calculate the resistance in ohms of the DC motor you would need to know a couple of things. First of all what is the voltage applied to the motor. Second of all, how much current did you measure in step 2. Now use Ohm's law where R = E/I. R is the resistance in ohms, E is the voltage and I is the current. 4. Many appliance have electric motors however, not many household appliance would use a DC motor because it would take additional equipment to convert the household AC to DC and since there are small AC motors readily available this is not done. Washers and Driers have a drive motors and timer motors. A microwave with a turning table would have a motor. Blender, refrigerator, furnace, mixer, garbage disposal, can opener....too many to hit them all. Now, some smaller household electronics such as computers, video games, vcr's dvd players, walkman's, etc. would have DC motors.
- Q: I have a Comfort Maker Heating Air Conditioning system/furnace and I noticed that I am not getting air through the vents. The dampers are in the open position. I switched (at the thermostat) to AC/fan on quot;AUTOquot; for 20 minutes, and I noticed that the squirrel cage and the heat inducer/motor was running while it was set on AC. Is that supposed to happen. I also ran it on heat and same result w/absolute NO heat/flame coming out of the manifold.Also, the whole time the system was running, the outside air handler unit never commenced.
- Sounds like a bad control board. The relay for the inducer motor is on that board. If the board shorts many will turn the inducer motor on as a safety. No flame up on heat is another symptom, since the inducer must be off when you call for heat. If the board is bad no A/C is also a symptom.
- Q: Dc I have motors, leds and such what can I power with ac
- AC is used for power generation and distribution, many motors, lighting, appliances, furnaces, electric stove, dryers, and other high power items. DC is used by DC motors, LEDs, most low power electronics equipment, etc. In most cases AC power is converted to DC for these applications.
