Q:If you cut the power to an electric motor and while it is still spinning if you put a strong magnet near the motor will it slow down more quickly with the magnet or without the magnet near it. Assuming that the external magnet is stronger than the magnets inside the motor. And is there a way to implement this without damaging the motor?: i dont think that would work. but if you are talking about creating a self powering/self recharging system then yes. most eliectric cars already have this technology. a battery that supplies power for the electric motor wich turns an alternator wich in turn creates power for the battery. presdo you've done it.

Q:i need help with a school project. im in high school.: An electric motor has a rotating armature, and stationary field magnets. The armature's magnets are usually electromagnets, and the field magnets are usually electromagnets in large motors, or permanent magnets in small motors. Whether it's an AC or DC motor, the rotation comes from the interaction of the armature with the field magnets, either attracting or repelling each other. It takes a very intense magnetic field to produce the forces that rotate the motor, and the magnets within the motor are designed to direct the fields so that they can interact strongly. Magnetic fields' intensity varies inversely with the square of distance from the magnet. That means if you move 2x as far from a magnet the intensity drops to 1/4 and if you move 3x as far from a magnet its intensity drops to 1/9. This means that for the motor to be powerful, its magnets must not only be strong, but very close to each other as well. So, what about an outside magnetic field? Will it affect the motor? Yes, it will, but the real question is - how much? Most magnetic fields in our world are not very strong, and not anywhere near as strong as those found inside a motor. In addition, the source of an outside magnetic field is going to be much farther away from the motor than the motor's magnets are from each other. Finally, most practical motors are enclosed in a metal frame that blocks magnetic fields from getting in or out. As a practical matter, a normal outside magnetic field would be too feeble in comparison with the motor's own fields to affect a normal motor. To have a noticeable interaction would require an exceptionally strong outside field, and a very small motor.

Q:alternators: No, not easily, at least not for single phase AC. Your alternator is a DC powered rotor coil in a three phase AC coil stator. The rotor needs DC current to produce the mag field. The brushes that power the rotor are fixed rings, they don't reverse polarity on rotation, so no DC motor action. Your rotor is not wired for induction nor are your stator coils, so no single phase AC motor action. You need a rotating magnetic field to make it work, you need three-phase AC supply and power the stator coils separately and a DC supply for the rotor. Then you will have a 3 phase AC motor. Easier to just buy a motor, though there are instructions on the internet for doing it. Google alternator as brushless motor

Q:what are the applications of ac dynamic braking?: Do you mean vehicle braking? Not as good as DC dynamic braking, which for vehicles, means you can recover the energy and store it in a battery. AC, you have to dissipate it in a resistor or in the generator itself.

Q:You have an AC current, and you want it to be a DC current without it pulsing. Here's my solution. You put the AC current into an AC motor. You then have the motor turn a DC generator, making a DC current. I think this will work, but I can't tell...: 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.

Q:Can the speed and torque of three-phase asynchronous AC motor be controlled at the same time?: More than 50HZ constant voltage, constant power, but the speed increases at the expense of torque, the above formula N becomes the working speed of the motor, such as 5.5KW 4P-50HZ, at 1000 rpm, torque = 9550 * 5.5/1500=35N.M at 2000 rpm. Torque = 9550 * 5.5/2000=26.2N.M

Q:I work on cellular radios and we always use a rectifier to convert the AC to DC. It seems like we should be able to use AC to run the equipment. What is the specific reason we can't?: As far as the radio is concerned, the circuitry is designed for DC. There are various circuits like diodes and transistors that can only accept one-way current, and if you push current the other way you can damage them. The primary reason for using AC is simply because electricity can travel much, much farther than with DC.

Q:Where are the low voltage AC asynchronous motors used in electric machines?: As long as the driving force is the place, basically used，Widely used in industry, agriculture, national defense, aerospace, scientific research, construction, transportation, and people's daily life.

Q:My AC induction motor has to run in indexing table application which works 24X7. Each cycle has 1.2sec (0.2sec idle). Hence per hour the motor has 3000 cycles. Iam having forced cooling fans on motor to dissipate the heat generated due to high start/stop. My motor brake (AC) releases within 0.04sec engaging within 0.007sec. hence the total braking action is about only 0.47sec. Pls tel me the 0.2 sec is enough for idle condition of motor.: Well as you know, S3 is intermittent duty, but I think S3 maybe something like 20 min run per hour. See the site below which states equal on/off periods I think. Better off replacing with S1 motor I would think, unless above 20 kW. or so.

Q:A sinlge phase AC motor is needed to lift up vertically a load of 150kg to 200kg using chain and gear. Please help.: Depends on how fast you want to lift it. With the right gears a tiny motor will do the job, although it may take hours.
