This serial products consist of wound rotor three-phase asynchronous motor,centrifugal fan and break-type electromagnetic brake. The
rmistors are embeded in stator winding
The motor brake is connected with shaft by spline. It is equipped with manual release device,which relieves the brake in the case of power
failure, so that it is easy to install and commission the motor or set down the heavy objects in the condition of failure
This type motor rotors are specially designed. Referencing the French technology, the shaft ends are closed by new-type hermetically
sealed construction, and the vriginative electromagnetic brake extends the life of motor airtight. When throwback is activated, the mechanical
and current impacts are smail,and also the vabration and noise are small. The comprehensive performance of this serial motors is greatly
enhanced
This type motors can be used to substitute those imported from France.
- 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:Trying to figure out how much current my attic fan draws and the label is scratched off
- In my electronics class we were taught that 1 Hp. is equal to 745 watts or roughly 6.2 amps. A half Hp. would be half that. NOW LISTEN CAREFULLY: Any figures for motors that you derive through anything but actual testing are only rough guesses. There are different ways to make motors and any number derived through calculations is just an educated guess. It, the calculated number, ignores all environmental issues as well as friction and who knows what else. Does that help??
- Q:Are dc motors more common than ac motors?
- If you include electronically commutated DC motors and stepper motors, in the home or office usually yes, as HDDs have one, most optical drives two to three, each PC type fan is one. A floppy drive has two motors. VCRs usually have 3 or more motors (I remember when VCRs boasted about how many motors they had). Kitchen appliances usually have AC motors. Mixers and blenders usually have universal type motors. HVAC usually uses AC motors, but modern A/C compressors and circulation fans could be computer controlled DC PM or electronically commutated motors. Hand held coded power tools are usually universal, fixed tools are usually AC motors. Cordless tools usually use PM DC motors. Toys use PM DC motors usually.
- Q:Hi, i got one of those baby swings that run on two D batts. They last about 1 week. There must be a coverter i can buy at radio shack, or something right? What would it be called? Thanks :)
- To covert AC to DC you use a transformer ..... the same sort of thing that you use to charge your car battery. But honestly mate, do you really want to muck about with DIY electrics on something you're going to stick your baby in ? Surely just buying some rechargeable batteries is a much better idea.
- Q:for example: 4-poles or 6-poles: which is difference i can see inside motor?
- yes if you can count the number of coils and interpret the winding configuration a motor rewinder at a repair shop can do this easily put it on a known frequency and measure the RPM - easier
- Q:howv does the AC electric motor differ from DC electric motor structurally. can we use AC 220 volt 60 watt ceiling fan case be used and changing coil and make it DC electic motor of 36 volts if so what power WATT should be given to give same energy output
- I think the simplest solution would be to get a 24V lorry radiator fan motor from a breakers yard and step down the voltage. or go one stage further and power from a photo-voltaic pannel so it works whenever the sunshines and automatically stops at night. rewinding the motor and fixing the commutator, brushes etc is likely to be difficult if not impossible without completly re-building from scratch.
- Q:I was curious if I rewired the AC motors on both the squirrel cage fan and outdoor unit to DC, and hooked solar panels directly to with battery backup, would that be anymore efficient than converting to AC?
- It really would not do you any good. The only power you'd save would be that which an inverter draws, and that's minimal. We live off grid and I can tell you that running a central a/c unit with solar will be exceptionally costly to setup and maintain. We use wind and solar and batteries and have over $25,000 in our system and I could not power a 220-v a/c unit.
- Q:I know AC motors have some advantages over DC in some applications, and the opposite is true in other applications. Most cars use DC motors when converted, but there was one professional model, The Sunrise by Solectra that had a huge range and highway speeds that used an AC motor. Why would that be the exception and not the rule?
- Alternating Current. Direct Current has a history of being dangerous.
- Q:Increasing the number of wire turnsDescreasing the strenght of the fixed side magnetsMaking more splits in the commutatorChanging to a power supply with more electical output.Help please!
- 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 . .
- Q:Hello everyone,I need help wiring up a pump motor that I just got to replace an old one. It is an Ironhorse Rolled Steel general purpose motor rated at 1 HP. It is dual voltage (115/230) but will be running it at 115V. It uses a T1-T8 system the colors are:Blue T1White T2Orange T3Yellow T4Black T5Red T8The wiring scheme for low voltage is:Line 1: Blue orange redLine 2: White Yellow blackHow do I hook this up to an AC power chord that has White, Black, Green wires?
- The motor will have a label with the acronyms: RLA, LRA, and or FLA. RLA and FLA are the figures for Amperage that the motor needs. A one hp motor is likely to draw about 16 Amperes at 115V. This is beyond the limit of most common receptacles. Be sure that you have adequate power. Dual voltage is used in large motors because of the high current requirement. At 220VAC the motor draws half the amperage. Lee26loo's instructions are correct (if your receptacles are up to it).
