Q:2000 Accord V6, changed motor mounts, AC not working now?
go get tested for leaks and new r 12..
Q:AC motor for wind turbine help?
no, not without a lot of difficulty. Stick with DC motors, and only ones with permanent magnets. .
Q:Car revs up when ac kicks on and now car is overheating?
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 motor/Compressor start up, the car revs up to about 1500 RPM and then comes back down. Any ideas on what it might be? ANSWER This is normal. 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. 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 reservoir 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? 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:Repair of 120 AC motor?
Try the link, I've had success with then in the past. Good luck!
Q:can you run a brushed ac motor on dc current?
Brushed AC motors are in fact serial DC motors. So, the answer is YES, you can. But you must do some maths not to overload it so it burns out. And (as in AC) it will not be a reversible motor! (i.e. if you reverse the poles, it will still rotate in the same sense).
Q:what is standard RPM of 1 & 1.5 hp motor?
Assuming an AC motor, it depends on the type, the number of poles, and the power line frequency in the country where it is used. In the US where the power line frequency is 60 Hz, a typical induction motor will run slightly below the synchronous speed of 1800 or 3600 rpm at full load. Depending on the amount of slip, nominal speeds of 1725 or 3450 rpm are common. In 50 Hz countries the synchronous speeds would be 1500 or 3000 rpm with nominal speeds once again slightly lower. A typical gas engine in that HP range might be designed to run at anywhere from 1500 to 10000 rpm depending on the application. Don
Q:Can i use an AC drill motor as a generator?
Drill Motor Generator
Q:How to ground an ac motor and add a switch to it to turn it off and on?
You don't need to install any extra switches, just install it properly and fix the existing wiring if that's the problem. zxc
Q:Disadvantage of AC Drive?
Speed Control The main disadvantage of AC motors, when compared with DC motors, is that their speed is more difficult to control. AC motors can be equipped with variable frequency drives, which provide smooth turning moment, or torque, at low speeds and complete control over the speed of the motor up to its rated value. Variable frequency drives improve speed control, but do create losses with reduced power quality. Control Complexity The device used to control an AC motor, known as an AC drive, is typically more complex than that used to control a DC motor. An AC motor controller must convert AC mains electricity to DC, and convert DC back again to an adjustable frequency and voltage output to the AC motor. By contrast, a DC motor has a separate field, or excitation, and power circuits, requiring just a single power conversion from AC to DC -- so the circuitry of a DC motor controller is simpler. Power Torque Historically, another disadvantage of AC motors has been that they develop less power, or less torque, per frame size. Research conducted by Rockwell Automation compared typical, commercial AC and DC motors in industry standard National Electrical Manufacturers Association (NEMA) frame sizes, and found this to be the case. However, AC and DC motors employ different classes of insulation and have different service factors -- the overload capacity at which the motor can operate without damage -- so direct comparison is not always straightforward. Other Disadvantages AC motors are typically more expensive than DC motors for most horsepower ratings. If the rotor of an AC motor rotates faster than the speed command of the AC drive, the motor acts as a generator and pumps, or regenerates, energy into the drive. If the drive cannot absorb this energy, the drive will switch off, or trip, with a fault. AC drives capable of regeneration are more complex and more expensive than DC regenerative drives. AC motors may also produce more audible noise than DC motors.
Q:How to make a motor spin faster without using more voltage?
If it is an AC motor, the speed will be set by the frequency divided by the mumber of pair of poles. One pair of poles will give you the highest speed, equal to the network frequency. Most AC motors are two pairs of poles. You can also use a variable frequency drive. If it is a DC motor, it will spin faster if you reduce the shunt field current/voltage. I.e., descreasing the strenght of the fixed side magnets . .
