Q:I am making a cotton candy machine and I need to be able to slow down the motor a little bit. Its 115 volts and 3000 rpms. I was told that I might need a special kind but Im almost positive I could use a regular house light dimmer. Which kind should I use?
There are several kinds of 115 VAC motors out there. The universal motor found in many home appliances will run slower if dimmed, but in reducing RPMs you also reduce power because you are basically choking off the motor's source of energy. Because the motor is running near its stall point it will have very little torque available (but since you're using it to make cotton candy, you shouldn't have any trouble there). Any light dimmer will work for this, but if you can find a cheap variac of the same current rating as your motor, you'll get better results. The majority of single-phase AC motors run at a speed that is determined by the windings and the AC line frequency, though, so a true AC motor will not run slower if you use a dimmer; it will only get hotter and produce less usable torque. The only way to slow down a motor of this type is to use a variable frequency drive (VFD) or inverter, which can actually change the frequency of the power supplied to the motor. But here you have to be careful, because unlike a three-phase motor, a single-phase motor cannot start at just any speed. If you get an inexpensive (under $200) drive with a keypad programming interface, you can set it up to start the motor at full speed and then slow to a preset RPM. Again, these motors are designed for a specific speed so you will lose efficiency when slowing them down, but your application doesn't need a lot of torque. eBay is a good source of cheap VFDs, but check to make sure that you select one compatible with single-phase output (and that your motor is also compatible).
Q:Relation of voltage, speed, voltage and torque of single phase AC motor
The speed and frequency are the same, because the supply voltage is constant, the frequency of the change, the result of direct reaction is the same speed change, frequency increase, speed also increased, it minus the other also reduced.On voltage analysis, look at these formulas.Motor stator voltage: U = E + I * R (I is current, R is electronic resistance, and E is inductive potential);And E = k * f * X (k: constant, f: frequency, X: flux);For asynchronous machines, T=K * I * X (K: constant, I: current, X: flux);It is easy to see that the frequency of F changes, is also accompanied by the change of E, voltage of the stator should also change, frequency control methods commonly used in fact is that, when the frequency changes, the inverter output voltage, also is the increase in voltage at both ends of the stator is changed, is proportional to the this is the ratio of frequency conversion constant V/f. Analysis of the three equations can also be used in front of the same results can be obtained.
Q:i have an omniblender that claims to turn this fast and my dad seems to think its not possible. but i think much higher rpms are possible, but the question is what kind of power is a motor going to need to turn that fast in terms of voltage, faze, amperage pull, windings. can a motor that weighs only 6 lbs do this?
The amount of power that it takes depends on the rotating mass and the load that is applied to the rotating parts. Blenders are usually gear driven to increase torque, so if the motor turns at 36000 rpm, the blades might be going at a different speed, or maybe it's the blades that turn 36000 rpm.
Q:I have this saw and the speed control board has gone bad,so i am going to try and use a variable ac or dc power supply to run the saw,but i am not sure which one the motor uses. I have already hooked the motor to a battery charger,it ran find but does not have enough torque for the blade to cut wood.
I can't imagine a contractor grade Craftsman 20 scroll saw running on DC. It doesn't make sense. If this thing has a normal two or three wire cord plug then it's certainly 110 Volt AC current. I don't think Craftsman ever made a scroll saw that ran on DC.
Q:The difference between a direct current motor and an alternating current motor
The principle of AC motor is complex, but the structure is relatively simple, and it is easier to maintain than the direct current motor. The direct current motor introduces the current into the rotor armature through the brush and commutator, so that the rotor is forced in the stator magnetic field to rotate. AC motor (AC asynchronous motor to commonly used as an example) is the alternating current into the stator winding, resulting in a rotating magnetic field in stator and rotor air gap, rotating magnetic field induced current in the rotor winding, the rotor stress in the stator magnetic field generated in the rotation. DC motor speed control is simple, but the use of limited occasions. AC motor speed control is relatively complicated, but it is widely used due to the use of AC power supply.
Q:The motor is an AC motor, with details:S#: C56A23193 Type: C Ser 2H97HP 1/2RPM 1425Code: KHSG: OpenPlease answer back ASAP! Thank you.
The serial number you mentioned would be the number for the entire motor not the bearings. To find the bearing needed you could take it to an electric motor repair shop, they may be able to determine the bearing size or remove them, measure the bearing itself and find it dimensionally. You'll need the shaft diameter, outside diameter and the depth of the bearing.
Q:what are windings on electric motor for a ac unit?
The copper windings react to the magnets in the casing of the motor, which repel the windings, and in doing so cause the motor to turn.
Q:I am trying to figure out how to make an bench grinder that has an AC motor with a DC power supply with out buying an expensive inverter. This is for class project and we are on a budget.
Can you tell us something more about the motor ? I think if we knew what kind of AC motor it is we could know about the construction and that will make it easier for us to think of a way to run it on DC supply. I think you might need a Brush and Slip ring assembly to be mounted on the same shaft as the motor so that the DC gets Converted in to AC.
Q:As soon as I turn off the heat, the whistling sound dissapears
Quite likely it is,- when bearings get dry they squeak or chirp the more worn the louder the noise and more frequent! I may progress to a point where it goes into a low growl At this point it is past worn out,- and will blow a fuse if let run very long (as it draws excessive current this way)! Are you talking about the blower motor-- (as turning off heat), -- or just changing the blower doors to another position, -- (blower still running)-like going from floor heat to defrost? If this is the case, then you might have a piece of paper or a leaf, - or a label off something trapped in a place where it vibrates like a reed in a musical instrument-- this would likely change with blower speed!
Q:I know its been asked before but I need advice on what kind of motor to use for making a rotisserie. I want to be able to add a potentiometer and have a speed of between 2 and 10 RPM. I was originally thinking of a washing machine motor but think that it may not have the power at lower speeds.I Would also like to do it with a direct drive instead of having loads of pulleys as featured on you tube, although i realize some gearing may be required.Thanks in advice people.
The motor in your link is rated 0.4 watts input and about 0.3 watts output. You need about 10 times that power for a small rotisserie. The speed of an AC motor can not be inexpensively controlled without losing torque. For AC use, you need a universal motor, an AC motor with brushes like those used in plug-in electric drills and food mixers. DC motors will also work. For the speed that you need, most of the speed reduction must be obtained with gearing,
