Light tower generator set :
- Q:Can the voltage regulating module be used as AC motor speed regulation?
- Ordinary three-phase AC motor (commonly used three-phase AC asynchronous motor) is the stator winding into three-phase alternating current, resulting in a rotating magnetic field (the rotation of the magnetic field speed n=60f/p, also known as synchronous speed). The rotating magnetic field is relative to the rotor winding (usually the squirrel cage winding), and the rotor winding induces the rotor induced current due to the electromagnetic induction principle. The rotor current produces a tangential torque under the influence of the magnetic field, so the rotor spins.
- Q:the difference in construction, what does 1 of them has that the other does not and what does this part adds to it and thanks
- what does 1 of them has that the other does not? usually a simple dc motor has a commutator and an ac motor has slip rings.
- Q:I am using the motor on a toy car.
- on a DC motor you can control the direction fo the spinning, and on an AC motor they olny have one way of spinning.
- Q:I have a 1.5hp 220v 3 phase motor driven band saw. I need to run it on a 220v single phase system. The original single phase converter consisted of a 550uF capacitor supplying the third phase winding with the contacts of an NC relay in series with the capacitor. The coil of the relay is from the supply through a resistor to the third phase winding and dropped out when the motor came up to speed. A second 40uF capacitor is from the supply to the third phase winding and is the only capacitor that remains active when the relay opens up (motor is up to speed). I'm looking for a simpler and more reliable solution, as the present circuit is temper mental and old. Replacing the motor is a last resort. Is there a simpler capacitor type converter that can be designed? The saw is only operated intermittently for 10-15 minutes on time, 30-60 minutes off for an 8 +hour period, for a few days a month. It is used for a meat cutting band saw. Any sources, help or information would be greatly appreciated. Thank you.
- Capacitor type converters do tend to be temperamental, but the circuit you have seems to be about as simple as they come. Rotary phase converters are generally considered much better, but are also much more expensive. Another option that may be practical due to the lowering cost of semiconductors, is a is a VFD inverter drive, while the name includes variable frequency you can just as well use it at a fixed speed. Just a couple weeks ago I installed 3 conveyors with singe phase to three phase VDF inverters (albeit wit smaller motor than yours) and they work flawlessly.
- Q:after changing the brushes on my wood router with a ac motor it is not working and both wires are live
- If just one brush is hung up in the passage, it won't work. Maybe remove them and inspect the brush-guide assembly and ensure the new brush slides in all the way down to the commutator/slip-ring. You can file brushes to make them fit better. Also, it's unlikely the problem is a dirty armature as another answerer suggested. Just spin the motor by hand in both directions and try it again. If it doesn't run, it wasn't dirt causing it.
- Q:The difference between AC motor frequency conversion speed regulation and voltage regulation speed regulation
- Voltage regulation: smoothness is good, speed range is narrow, can not be used for constant load speed regulation.
- Q:are dc electric motors cheaper to operate than ac motors and why?
- DC motors, if you are talking brushed, vs AC motors or Brushless? OK, it depends on the situation, but: Brushless motors have less friction, all other things being equal, and can be somewhat more efficient, wasting less electricity. Brushless motor controllers, if you are operating from DC, can be a bit more complicated, expensive, and a bit less reliable. However if you are operating from AC and the motor is matched to the incoming AC, i.e., 110vac 60 cycle, this is negated. Same for DC brushed motors. If they are operating from the correct voltage DC supply, then the controller is minimal, but still a bit of resistance from the brushes. However, to answer your question as asked, negating the start-up costs, a correctly designed AC motor operating from matched AC is the cheapest to operate- minimal controller, maximum efficiency. After that, brushed or brushless motor on DC , or brushed motor on AC, just depends on lots of different parameters, cost of failures, etc.
- Q:I had an HVAC tech check the AC units on a house just before I bought it. He said on one of them, the condenser fan motor is quot;locked upquot; (his words), well, I went up there to check things and the fan spins just fine, however the motor won't start. It won't start if I spin the fan with a stick either.He quoted me $425 to replace the motor, but I think I can do it myself. Is there a place that would sell me one?Also, the current motor in there is not the original one (The unit is an old 50YG500514 Carrier. It looks like someone replaced the fan motor before with an Emerson 1/4 hp motor. The wiring looks different. (I have another unit exactly like it that works fine, and that one has a GE motor).
- Check and make sure you match a generic motor with frame / horse power / Voltage / RPMs/ and proper rotation. The original motor horse power is important to match. If the new motor requires a run capacitor, have the seller match one for you. Haul the motor to WW Granger. I think they are nation wide. they can match it up for you. they have a web sight too. Some motors are universal motors who's rotation can be reversed by exchanging two sets of motor leads with instructions attached. Good luck. Rangefinder
- Q:my friend tells me its really bad for your car or the ac motor or something, is this true?
- No, it's bad to sit in your driveway with the AC on. Windows have no affect on that, except it's really hard to cool off when the cold air is rolling out the windows. AC compressors put a lot of strain on an idling motor. If you are sitting still, you have no air circulating through the radiator to cool the engine. That's probably what your friend is talking about. Traffic stops, drive thrus shouldn't be an issue. It is a good habit to always monitor your temperature guage as well as oil guage when you are operating a vehicle. If you are sitting still with the AC on and the guage starts to go up, shut off the AC and roll down the windows. The temperature will start to drop on the gauge.
- Q:I am trying to determine the power requirements for an AC Motor for 2 types of wavemakers; Plunger and Flap.Here is the layout of the plunger and tank
- I think you need: F= Discharge (in m^3/s) * Speed Speed can be calculated according to you data. Discharge would the amount of water displaced every second, in m^3/s. Use P=F*V, should get you the power.
