Q:Which type of electric motors are more powerful a.c or d.c?: AC motors can convert more power per unit of mass and more power per unit of volume. In a DC motor, almost all of the input electrical power must pass through the commutator. The commutator adds size and weight and reduces efficiency. The design of the rotor windings also requires more copper and reduces efficiency. Lower efficiency means increased heat requiring a larger motor. In the case of a brushless DC motor, there are permanent magnets in the rotor making it more like an AC motor and possibly somewhat more powerful than an AC motor of equal physical size and mass. In addition, AC motors can be manufactured in power ratings that are not possible with DC motors. The commutator limits the maximum voltage and current. AC motors can operate at higher voltages. An AC motor has been manufactured for 101,000 kW (135,000 Hp). It has two 12,500 volt, 3-phase stator windings.

Q:Hi, I was wondering how to connect my FASCO model K628 motor to a AC power plug. It says: brn- commonblk-208v Red, Orn,Orn 230v Its my first time doing this, and I'm really confused Thanks!: This is a single-phase motor for use on either 208 volts or 230 volts. You need either a 208 volt or a 230 volt source. For 208 volts, connect one hot wire to the brown motor lead and the other to the black motor lead. Tape the Red, Orn, Orn lead so that the bare end can's touch anything. For 230 volts, connect one hot wire to the brown motor lead and the other to the Red, Orn, Orn motor lead. Tape the black lead so that the bare end can's touch anything.

Q:Ok basicly the harddrive motor i have has 4 contacts... I attached 2 wires to the most likely contacts i thought would make it spin but all it does is spin for like 2-3 seconds then it stops?? How can i make the motor spin? INeed it for a project because of its high rpm.: mine has four contacts also and it says on the little label that it starts on a certain voltage. maybe you don't have enough? maybe there are four contacts for two coils inside and maybe it can't run off of just normal voltage but maybe two phase?? just a guess.

Q:it has 3 wires coming out, what are they for?: Two are for the AC power and one is for the ground, Im guessing. If they are very light guage wire it could be for some sort of remote, but since its old who knows. Any pics?

Q:how to convert 12v DC to AC three phase, to run converted car alternator as a motor.?: It has to be way less expensive to just buy a motor for what ever you need it for. The alternator will not have much power should you figure out how to make it work.

Q:ac motor to ac generator?: The DC motor has a fastened magnetic field created by potential of the two an enduring magnet or by potential of DC contemporary flowing by way of a field winding. The armature has a winding that rotates interior the fastened field. A DC contemporary utilized to the armature winding will result interior the armature rotating to the component the place the magnetic field of the armature is aligned with the fastened field. At this component the armature might end, by no potential to teach anymore. So there's a gadget referred to as a commutator on the armature shaft that's used to prepare contemporary to the armature winding AND to opposite the path of contemporary pass in the process the armature on the component of rotation the place the armature might otherwise end. as a result while the armature approaches the component of field alignment while it would end, the present path is without notice reversed by potential of the commutator, and the fields are bucking one yet another and the motor keeps turning, and this technique repeats itself consistently. The DC motor will enhance right into a DC generator despite if this is pushed by potential of an exterior source of mechanical skill. If the commutator function have been faraway from the DC motor and altered with slip jewelry that habit contemporary to the rotating winding with out reversing the path of contemporary pass, and if the motor have been pushed be an exterior skill source, you at present have an AC generator. The voltage and contemporary generated as a result will opposite path each 0.5 turn of the armature because of the fact the windings are crossing a magnetic field of opposite polarity.

Q:I just took an Ac electric motor from an old broken washing machine and I would like to use it for a project but I dont know how to wire it to make it work. Im trying to build a machine to roast pigs over a fire but i need help because i dont know how to set up the motor. if some one can explainto me how it works, it would be very helpfull. There are two white wires going to the top and three others, black blue and red, going to the coils. On the motor, it says its a 110v Ac - EL (CL F) 16000 rpm 50/60HzIf some one could help me or show me where i can learn all i need to know, it would be very helpfull.: Hi. I'm going to assume this motor is a shunt motor (parallel wound) which means it has a good constant speed but low starting torque. And the rpm seems alot. are you sure it's not 1600 rpm? Either way you would probably have to get some gears built into as cause you don't want that pig taking off. There are other speed control options depending on the type or motor it is. So to power it you're gonna need a transformer ( unless you're in a country where 110 is standard). You're gonna need to wire a motor starter into it. This will consist of a start/stop switch, a contactor, an emergency stop, a breaker (the rating of this will depend on the FLC (full load current) of the motor, and you will need a TYPE C) and to protect the motor you'll need some thermal overloads. This can also be 110v so you won't need a transformer. I can explain how to wire it using what I know and using the equipment I use.. You should be able to start it DOL - direct on line, which means you can start it from the mains without adding extra starters (star/delta) 1.You take the power into the breaker and out into the contactor. If it's a single phase 110v contactor the numbers are normally 1 (in) and 2 (out). 2. You then take it from the out and into the motor. That's your power done. For the control you need to... 1. Take some 110 power from the incoming power and start from the emergency stop. 2. If you are using a thermal overload connect from the emergency stop to 95 on the o/l. Then take it from 86 to the stop switch (1). 3. Then connect (2) to number 3 on the start. The holding contact needs to be in parallel with the start button so you need to wire 3 to number 13 aswell. 4. (4) from the start button needs to go to number 14 AND A1 - which is the actual coil. Then you finish off with A2. Easy peasy lol. I hope you've understood my waffling... Good luck

Q:what happen if direct current is supplied to ac motor?also what happen if alternating current is supplied to dc motor?In which case motor makes to and fro motion(vibratory)?: i think motor will burn out

Q:hey i have four questions for yas most apprieciated if you can help!!!Question 1Where does the energy that makes the DC electric motor work originally come from?Question 2What difficulties would you have measuring the current flowing through a DC electric motor when it is operating?Question 3Please Explain how you would calculate the resistance (in ohms) of a DC electric motor circuit.Question 4PLease name as many appliances that have electric motors in themplease and thank-you if ya answered!!! PEACE OUT :D: 1) Are you asking how does a DC electric motor produce energy? The simple answer is that by changing a magnetic field around a coil of wires, you induce an electric field. Inside of a conductive piece of wire an electric field will push on electronic particles (like electrons and protons) and force them to drift towards the area of lowest (or highest depending on the particle) area of potential energy. Theres quite a bit of calculus involved in a better explanation though. 2) Well practically it would be near impossible to go near an electric DC motor while in operation. Essentially is a big coil of wires with magnets spinning around it. Aside from being shocked, I dont think you could get close enough to do any type of measurements with a DMM. 3) I suppose your asking how to calculate the internal resistance of a device. There are several ways to do this, depending on how much you know about circuits. One way is to apply a known load to a circuit and measure the voltage drop across it. You can then do a bit of voltage division and come up with an easy answer. This is due to something called the loading effect which basically says that as the load on a circuit increases the effect of the internal resistance of a source (dc motor) decreases. 4) I'm sure you can figure this one out.

Q:Basically, I want to control an AC motor where the end user will only have to push three buttons. One button would be quot;lowerquot;, in which the motor would turn for a certain amount of time and stop at the desired time. The other button would be quot;raisequot;, which would turn the motor in reverse for the same period of time and stop. And the third button would be quot;stopquot; to stop the motor at any point along the way.To describe what I'm talking about, basically I'm making a electric projector screen. So the user hits quot;Lowerquot; and the screen goes down to the exact point it's supposed to.Thanks for any help!: you really don't want to control this with timers. You want to use limit switches to stop it when it reaches the limit. Otherwise it would stop at the wrong spot as the motor bearings aged, or if the line voltage were off a bit, or the track grease wore out. And it you are going to design something this complicated, you need to think of all the contingencies, and more.
