SIEMENS AC Motor

Q:What does it do, what industry is it from, and what is it mainly used for by industries?: The standard every-day induction motor is a squirrel cage motor. The term originates from the placement of rotor bars equally around the rotor, and then shrting the ends of the bars together with a conductive ring of some form. This makes it look like a squirrel wheel or hamster wheel. It is one of many different types of machines built by electric motor/generator manufacturers (others include wound-rotor induction machines, synchronous machines, permanent magnet machines, and direct current machines, and linear machines). It is by far the most commonly seen version of an electric motor in the world; it has been used historically for processes that require high starting torque, single speed, and relatively high stall capability. Also, since the majority of the world's utilities generate AC power, it uses the available power directly (unlike a DC machine). With the increased popularity of power electronics and the development of frequency converters, the induction machine is now used in processes that require variable speed as well. Typical processes include all those that are 'flow' specific; compressors for refrigerant and coolant, fans for airflow, water (or other liquid) pumps, high-speed drills (like oil rigs), and so on.

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 is the 'A' Dimension of an AC electric motor?: A also stands for Amperes. But not when it is part of AC.

Q:How to change DC motor to AC motor?: Asynchronous motor speed = (60* frequency / pole count) * slip rate.

Q:Why is DC motor speed regulating better than AC?: As long as the DC motor changes the armature voltage, it can speed up, but the AC motor needs to consider the stator and rotor coupling problem

Q:It is the chiller plant pump and we were trying to run the pump,unfortunately the motor was damaged.so what could have happened to this motor.: Just a big, old-fashioned short circuit.

Q:I work with electricity frequently enough and I have a motor that I want to use as a generator/alternator. Its a universal motor so it can be run on AC or DC. Currently I can't find my multimeter and I am having problems finding a answer through searching. So I need to know, when I spin a universal motor am I creating alternating current that I will need to add a rectifier to so I can run a DC component...or am I creating DC? I ask because I have a motorized bike and I just found a sprocket drive motor and I want to use it as a dynamo for lighting, and I want to rig it to DC battery storage as well. Or if you have ideas for circuitry on my specific project that would be even better!: you pick a mechanical potential of spinning the motor, the path of the rotation would be certain the order of the levels interior the output. in case you turn the path of rotation, you will replace the order of levels. that's acceptable to 3 section autos. some autos can in simple terms be became around one course so pay interest or you will smash your brushes in a hurry. you will could desire to spin the motor on the precise speed this is indexed on the motor's faceplate or you wont see the 60Hz or the output voltage you assume. in case you will attempt to power electronics with this AC generator you pick extra aspects to normalize the frequency and voltage or you will in all threat blow issues out whilst your RPMs replace under a load / no load situation. you apart from could could desire to be sure the RPMs are consistently consistent or your output will selection notably.

Q:hey please help my assinment id due soon and i cnt fail!!! lol mum will kill me!!! i have a few questions please if you are answering tell me which question it is from thanx and please help :D!!!Question 1:How do you tell if an electric motor is AC or DC. AC is alternating current and DC is direct current.Question 2:How could you measure or calculate how much power (in watts) an electric motor produces?Question 3:Please explain where the force comes from that makes an electric motor move.Thank you soooo much to the people that actually helped!!! :D: Q1. a DC motor only has one coil of wire, and a left and right magnet. (Single Phased) An Ac motor can be two or three phase. so the AC motor has more than one coil of wire. Q2. power = amps x voltage.... the voltage applied times the amps applied would give your power in watts. amperage can be measure with an amp meter. Q3. The force that moves the motor comes from electromagnetism. There are magnets and coils in the motors. When the coils are energized with they become magnetise and the opposed the magnets forcing the rotor (in which usually the coils of wire are) to turn For more info read on wikipedia

Q:Approximated dimensions are 7quot; dia, 14quot; length.: I assume you are looking for a replacement. This seems like a spindle motor for a NC machine, but my search didn't find one with all the characteristics mentioned. The clue is 8000 rpm. This is probably a 4 pole motor, so frequency is up to 266 Hz AC supply. It means it works with a variable speed drive, so may be married to that closely (I mean, I am not sure if you can substitute). It may even have speed sensing associated. It is this drive that produces the 460V and the appropriate frequency for the rpm which will be related to V/Hz. These motors are usually meant to be smooth running. Check the spec you gave carefully. It seems too small for 75kW and too fast for 75kW too. Still @ 8000rpm this may be possible. It may be that you can only buy a replacement from the manufacturer/supplier of the NC machine at great expense. Consider a motor rewind and new bearings, whatever (get it refurbished). This might not be so difficult or expensive, but once again, 75kW @ 8000 RPM? Maybe the re-winder needs to know what they are doing for that sort of balance. Some of these have exotic bearings too.

Q:I will be really happy enough if this answer is answered more reasonably in a simple explanation. What is the real difference between a DC and a AC motor? I know about the alternating and the direct current. One flows in reverse ad the other in one direction. But that's not clear enough. Please help me out.: A good explanation requires diagrams which can't be included here. It is important to understand that the direction of the force on a wire in a constant magnetic field depends on the direction of the current. Reversing the current direction reverses the force. The force's direction must change each half-rotation to keep the motor turning. This force-reversal can be achieved by: - in a DC motor using a split ring commutator and - in an AC motor having two slip rings and using the fact that AC reverses direction each half-cycle.
