- Q: well... our daughter is kinda dingy... anyway, yesterday my wife I had to run a few errands we noticed the weather was nice, so she called our daughter at home to tell her to open the windows turn the thermostat all the way up so the ac wouldn't run. We got home 5 hrs later she had turned it up all the way, BUT also set it to heat !!! Our house was like a sauna !!! Ok, so flipped it to off left the dial set to 85. It should shut off, right? nope. This am, left it on 85 moved the lever to ac. it should shut off, right? Nope, it's been 15 mins the blower is still running.Now what do I do? Up to yesterday it was working fine. I can only assume that ac/heat switch has broken,
- two are for te fan operation range the third is for high limit. there should be about 30 degrees between the fan pointers the higher one set at about 110. the last should be set at about 145. once the fan switch has engaged it will not shut off untill it gets below the low set point. for the sumer you can set the lower set point right up against the cut in pointer both at about 110. you should have no trouble then. Dont forget to set the cut out back down to about 75 or the furnace will short cycle in the winter.
- Q: Okay well first off our ac was running awesome and then one day the unit stopped spinning outside so we called a professional he came out and said that the capacitator(not sure how to spell it) burnt up which was not uncommon in this heat then he said we needed to change our filters he hosed it all down recharged the freon, a week later it compeltely freezes up, the outside unit was spinning but nothing was coming out of the vents , so we let it thaw out call him he comes out says our blower motor was getting stuck so he readjusted it said it was working already cooling our house down! Awesome except it froze up again! So we call him again and he tells us that our blower motor in our furnace needed replaced, so we replaced that ... We fall asleep to a hot house hoping it would get cooler threw the night w our running ac again only to wake up to it being frozen again ..... Please help ...
- You AC guy, like most others I've run across, has absolutely no idea what's wrong with your system. They are taught in AC school that if this happens, replace that. If that happens, replace this. They are not taught HOW TO TROUBLESHOOT! I've had so called AC techs try to tell me that the motor will cause the capacitor to fail or the capacitor will cause the motor to fail. I've been in electronics for 43 years. It will not. A failed capacitor will prevent the motor from starting or running. Sure, he replaced the capacitor because the motor stopped running - it's a run capacitor needed for the motor. That was the easy part. Cleaning the coils by hosing them down is a maintenance action, not a repair action, unless it was extremely clogged with dirt. I doubt the blower motor was getting stuck and needed adjusting. There is no adjustments for AC motors. If the motor was bad, he should have caught that on the 1st visit. You may have bought a motor you didn't need. He's cleaned the coils and recharged the system (which I doubt was he problem either). I'm not an AC tech, but I believe you have a restriction in the refrigerant line going to the evaporator. That restriction is acting like the expansion valve causing the evaporator to ice up. A plugged or severely restricted expansion valve itself may be the problem. That's what the problem was with my unit. The restriction could also be a kinked refrigerant line going to the evaporator - that was the problem with my daughter's unit. IT'S NOT YOUR COMPRESSOR. The fact that you can create ice tells me the compressor is working. But if the problem isn't fixed soon, you could lose the compressor due to high head pressures caused by the icing problem.
- Q: Hey guys, my AC tries to start outside it seems, but then i hear a big BEENG sound for like 4 seconds (as if the AC tries to start). Then it stops. I have a digital thermostat and its showing all 8888. I tried to stop the circuit breaker and restart it to no avail. It's the unit outside that seems to be the problem.ANy clue what's going on here and how much it will take to fix it?
- could be all that is wrong is your capacitor has gone bad...these give the compressor and the fan motor a boost when starting...each item can have its own capacitor or they can be both connected to a dual capacitor...you might also need to put a hard start kit on your compressor...a spp-6 hard start added to the run capacitor will give your capacitor a much larger boost at start up...they are easy to install with one lead going to each side of the compressor capacitor or on a dual capacitor one lead will go on the c or common terminal and the other lead will go to the h or herm terminal...you can bleed a capacitor by taking a screwdriver with a good insulated handle and using the metal part of the screwdriver just touch it to both capacitor terminals at one time...be sure power is off unit before attempting any repairs...
- Q: Is 3 phase AC induction motor specified in terms of Voltage, Current Power. I have heard that a motor can be operated over a range of volt, current power. then what do the rated values indicate. Also if a motor is specified as 48 V AC, 300A then can it be operated with a battery that could supply 48V DC... neglect all the losses the need for an alternator. Thanks in advance...
- The rated voltage is nominal voltage for which the motor is designed. The voltage can vary by plus or minus ten percent or so and the motor will still deliver the rated power without overheating so much that its useful life will be significantly shortened. The rated power is the power that the motor can deliver to the load 24 hours per day, seven days a week at rated voltage and rated ambient temperature for its expected lifetime. If the load is a little higher the motor's life will probably not be effected too much particularly if the temperature is not always at the maximum. If the load is less than the rated power, the motor will probably last longer than expected. The power delivered will be only what it takes to drive the load, so it can be much less than the rated power, but the motor will be less efficient if the load is a lot less than the rated power. The rated current is the current that the motor draws when it is operating at the rated voltage and delivering the rated power. If the voltage and/or load are above or below the rated values, the current will be above or below the rated value. Over a small range of voltage variation, the current changes in the opposite direction as the voltage change so that voltage multiplied by current will be about constant. Any battery of any voltage and sufficient power delivery capability could supply power provided that the DC power is converted to an AC voltage and frequency that are appropriate for the motor.
- Q: Criterion of selection between a AC and a DC motor advantages and the disadvantages of them?
- Since you are asking for the criterion of selection, here it is.. AC motors have two coils: an outer coil to produce magnetic field, and an inner coil to produce counter electric field. DC motors have an outer magnet, and an inner electric field. DC motors need DC voltage supply, and since all of the household supply is AC conversion is needed (thus making DC more inefficient, although the loss is minor) AC motors give better torque than similar DC motors. Since AC motors have two ciols, the magnetic field between the two colis can be adjusted to give maximum efficiency or power (something that DC motors cannot do)
- Q: If you cut the power to an electric motor and while it is still spinning if you put a strong magnet near the motor will it slow down more quickly with the magnet or without the magnet near it. Assuming that the external magnet is stronger than the magnets inside the motor. And is there a way to implement this without damaging the motor?
- You do not specify if it is a DC or AC motor, but that should make no difference. Yes it will slow down faster and No you can't do it with out damaging the motor. You will likely cause the rotor to hit the armature damage the bearings. Also there the question of interfering with the current generated with the still spinning motor rotor, Those could be high enough, if the magnet is large enough, to exceed the insulation capacity and short the armature.
- Q: Heater &AC blower motor will not work in 2000grandam se? Already replaced blower and resistor.Still nothing?
- Check the fan switch, it may be shot.
- Q: AC servo motor why drive?
- Servo motor control is more complex, you need to change the frequency, voltage, current, in order to achieve the motor speed, torque, position of the overall control, servo drive is dry. The servo motor is only responsible for how much frequency and voltage you give me, so I'll do the right thing. Changes in frequency, voltage, direction, etc., are handled by the servo controller.
- Q: Hi i am looking for a company that makes hollow shaft ac motors , it is american company that is called US , but i cannot seem to find it anywhere , i tried googling for it but obviously the brand name ( US ) isvery common that i get a lot of results that i am not looking for , can any one help me with this brand , if there is a website or something for them i woud really appreciate it

- Q: what is the connection of single phase AC motor rew and fwd?
- In AC single phase motors to reverse the direction of rotation of motor, you have to reverse the direction of the magnetic field. To reverse the direction of magnetic field interchange the winding wires.
