Q:AC>DC output to run 24VDC / 5A motor.?
You were told right. Motors can draw more that rated current on start-up and when loaded down and power supply ratings are for resistive loads, which your motor isn't. I like to have a power supply with double the motor's running current if I can, or 10 amps. It will only take 2 amps 120VAC into the supply to get that much DC, so you're OK there.
Q:why a ac motor burn due to heavy load and low voltage?
With an AC motor running on a reduced voltage, slip is increased. That is the difference between the speed of the rotor and the rotating magnetic field in the stator, increases. When this happens more voltage is induced in the rotor bars, so more current flows in them. By transformer action, the current in the stator windings also increases and may lead to overheating and burn out.
Q:How resistance is produced in an electric motor? and if its not produced then why don't shock circuit occurs?
Hi, The electrical circuit that possesses resistance are the windings of a motor.A motor has two types of windings viz. Field windings and Armature windings. See,when we talk of only resistance then it is logical to understand the theory of a dc motor only(NOT ac motor) in regards to your question. In general,the resistance of field windings is maintained HIGH by using a coil of larger number of turns made by thin copper wires as the resistance is inversely proportional to the area of cross section of the wire. This is because,the initial applied voltage to the field windings is very high and may cause to generate a large current in field circuit in case of low resistive windings.(Remember Ohm's law). This initial transient current is very damaging and so undesirable for use in the field circuit. On the other hand,the resistance of armature windings is kept LOW by using small number of turns made of copper wires of larger area of cross section. This is because the armature circuit is rotary member of the motor and has capability of self limiting the resistance in the form of BACK EMF. Even the initial value of current is very much high in armature circuit too but the use of STARTERS limit the current by grading the value of effective resistance.Once the rotor attains sufficient rpm,the generation of BACK EMF now,limits the current in the circuit and starters are removed. So,this is a misconception that motor circuits do not have resistances. HOPE IT WORKED!!!
Q:will a brushless dc motor work underwater if you just varnished/sealed/coated the windings?
First of all as per my knowledge there is no DC motor which can work without brush armature. Sealed type AC motors are available even immersion type which can work in the water. The varnish is not guaranteed against water protection, there could be leakage currents possible dangers
Q:Braking principle of 220V alternating current motor
AC motor and its controlAC motor is divided into two categories: asynchronous motor and synchronous motor. According to the number of stator phases, asynchronous motors are divided into single induction motors, two-phase asynchronous motors and three-phase asynchronous motors. The three-phase asynchronous motor is widely used in industry and agriculture production because of its advantages of simple structure, reliable operation and low cost.
Q:If u connect a DC motor to AC will it run or burn up?
Most converters won't handle the load of a motor. Find the load in amp.s, (It will be on the motor). Multiply the amps. x 12V. This will give you the running Watt.s. Multiply the Watt.s x 2 to get the minimum transformer size. (Motors need the extra capacity to start up). Buy a 120/12V. transformer of at least that capacity, and a 12V. rectifier bridge with minmum twice the motor running amp.s capacity. Buy a single pole light switch. Wire your 120V. power to the switch, and then to the line side of the transformer (According to Code please). The wire the transformer to the bridge. Wire the switch and thence to bridge to the motor. Given up the idea yet? Do be sure that there's a manual latch to get you out of your Secret Room in case your amateur lash-up fails.
Q:Why do they still make locomotives with DC traction motors if the DC system is inferior to AC?
The only advantage i see to AC units is the ability to cut out a traction motor and still have dynamic brakes on the unit.And the dynamic on an AC unit will work virtually til you stop, whereas a DC unit fades out just before you stop.And i've never had to do it but on an AC unit you can reverse them and use them to hold your train on a hill if need be.I think the AC units with all the reliance on computers are going to be a pain after they get some age on them.A railroad environment is harsh and only time will tell if they can stand up to it.
Q:Why is DC motor speed regulating better than AC?
The magnetic flux can remain the same when the excitation voltage is constant at the time of DC speed regulation.
Q:What's the difference between a three-phase AC motor and a two-phase one?
No motor, motor what you say is a single-phase motor, that is, the next two lines Oh, that is a live wire connected with a zero line, it is called a single-phase motor, three-phase motor is connected is three FireWire (FireWire is a phase, commonly known as FireWire only), rated single-phase motor the common voltage is 220V, is commonly used in industrial production, mainly for civilian use, because it is not efficiency of single-phase motor three-phase motor is high, so once the power requirements in kilowatts, or thousands of Watts will choose a three-phase motor, like motor home are generally single-phase motor, because the load is small, like in the industrial production of some motor to 5000KW, if single-phase motor, the other does not, the line is much more coarse!! In fact, there are two single-phase motor windings, a working group is winding, which is the main winding, a group is to start winding, is a secondary winding, due to single-phase motor single-phase power supply, so it will not produce a rotating magnetic field in the winding, but the pulsating magnetic field generated by the pulsating magnetic field will not generate torque, so the motor will do not rotate, so give him a start winding power supply starting winding is drawn from the power supply of the main winding, but the middle of the device can be shifted (such as capacitors) such a current through the device with different phase after the current phase, also became the so-called phase, resulting in the rotating magnetic field in the windings, the motor will rotate the rotation principle of three-phase motor, I will not say, all the same! The only reference is three-phase alternating current, without phase-shifting! To answer your question directly, the main difference is the different nature of the single-phase and three-phase power supply (I think so, hehe), the applicable scope of single-phase motor is mainly used for the power supply voltage of 220V, load is not the case!
Q:New AC to DC idea, but will it work?
Yes, it will work, but it's not nearly as efficient as the traditional method of a bridge rectfier and capacitor bank. The AC motor will not be more than 90% efficient, and the DC generator will not be more than 90% efficient, so the whole assembly will not be more than 81% efficient. The bridge rectifier/cap bank will easily be more than 95% efficient.
