Q:Is the motor of a washing machine AC or DC? ?
Ac Washing Machines
Q:what are the differences between ac and dc generating motors?
I think you are talking about electric generators rather than motors, although the problems are similar. AC generators are more simple ----they have a rotor coil rotating inside a stator coil which generates a magnetic field. The voltages induced in the rotating rotor coil is fed out via a brush commutator to outside wires. The DC generator is similar except that the commutator is more complex. It reverses the positive-negative polarity as needed to keep one output wire positive and the other negative. This involves reversing the connection to the rotor as needed during rotation. The AC voltage from an AC generator can also be converted to DC with a diode rectifier, which in most cases is preferred (less cost, more reliable --less wear). A car uses an AC generator (alternator) for this reason.
Q:what could cause ac unit to freeze up and motor to continue running?
The outside of the evaporator froze up. The evaporator is the part in the HVAC plenum under your dash. If you were to see it, it would look like a small radiator. Warm air from the outside passes through the evaporator which is chilled from the refridgerant (probably R-134A) running from your AC compressor. If you keep the AC on long enough, humidity from the outside air will start freezing to the outside of the evaporator. Eventually enough humidity could freeze and block the flow of air through the evaporator. The ice is of course on the outside of the AC system, so the refridgerant can still flow. since the refriderant is still flowing normally, Your AC compressor continues to function normally I assume the motor you mention is your AC compressor If you mean your blower motor, then the AC freezing would have no effect on the blower motor because cars arent wired that way. Not only does your car have no idea that your AC is frozen, but it would have no way of telling the blower motor to turn off because of that.
Q:Where can I find advice on troubleshooting ac induction motors?
Yes the capacitor could be faulty or the centrifugal switch or a bad winding or connection. The switch being easy to test as it should be made with the motor stopped. The capacitor probably best to check by changing it. You can do a rough check on the windings with an ohm meter but this may not tell you if an internal fault is shorting some of the windings but if its not the switch or capacitor then the thing's probably junk anyway. You think the load is the same but this is a big motor for single phase and compressors are hard to start so you need to be sure. Single phase motors can be a ***** when they don't work so good luck.
Q:how can we determine ac motor or dc motor?
The only wire accepted by the NEC and european community as being dedicated is the green wire that means earth ground. The green wire can have a yellow stripe around it but it its still earth ground. Today, then a motor that has brushes is DC and a motor that does not is AC. If I am confused then I always find the source of power and then it becomes apparent. In the european community then the brown wire is hot and the blue wire neutral with single phase. In the American commuity then the black wire is hot and white wire is neutral with single phase. Always measure the voltage with a proven good voltmenter.
Q:Is it possible to use a 50 Hz motor to a 60 Hz power supply without using any frequency converter?
It is possible to use if the load is light. Only thing that changes is speed of motor, instead of 1500, it will be 1800. Hence mechanical friction is slightly more, but a good motor must be able to withstand it. However if you load it up to say70% then that should be compensated
Q:What is an AC motor exactly? i need help!?
A motor that runs on alternating current as opposed to direct current. There are several types, also things like drills tend to have universal motors that will run on either.
Q:Along with coils in a 7.5 HP AC motor, Are magnets are used?
without magnets, no motor. The electricity provides the electromagnetic force to turn it
Q:How did the electric motor change the world?
When the electric motor Faraday invented is turned into a turbine; run by wind, water, steam, etc. it becomes a generator and produces alternating current. Thus his electrical motor design has a two-fold purpose. Many products have motors running on the same principle today - vacuum cleaners, power saws and so on - even heating and air conditioning units which force air through buildings and homes.
