What is the difference between a "motor circuit protector" and a thermal magnetic circuit breaker?
545118
A motor circuit protector (MCP) is a magnetic only (short circuit only) device that will operate under short circuit conditions in excess of its instantaneous tripsetting.\n\nThermal-magnetic circuit breakers have a thermal circuit interruption function and a magnetic interruption function. The thermal function uses heat-sensitive bimetallic elements that respond to overload electrical currents. The magnetic function responds to very high current overloads such as those that might occur during short-circuit conditions.\n\nIt looks like the significant difference is that the thermal-magnetic circuit breakers use both thermal and magnetic interrupts, while the motor circuit protector only uses a magnetic interrupt.\n\nI hope that this helps.\n\nCheers\nAlister\nhttp://www.marketscience.com.au

From looking around, I would believe it's a canadian classification for fireworks/explosives, but I can't seem to find a direct link to the canadian references.\n\nAh, found it.  Look at part 3b, and you'll see that 7.2.3 covers Single Use Standard E & F Motors

A Thermal Interface Material (aka TIM) is used to fill the gaps between thermal transfer surfaces, such as between microprocessors and heatsinks, in order to increase thermal transfer efficiency. These gaps are normally filled with air which is a very poor conductor.\n\nThey take many forms. The most common is the white-colored paste or thermal grease, typically silicone oil filled with aluminum oxide, zinc oxide, or boron nitride. Some brands of thermal interfaces (notably Arctic Silver) use micronized or pulverized silver.\n\nAnother type of TIM are the phase-change materials. These are solid at room temperature but liquefy and behave like grease at operating temperatures. They are easy to handle and are not messy.

Impedance is related to alternating current Circuits.\nResistance is related to direct curent circuits. It has the Unit of inverse velocity. hence resists the motion of electrons in a conductor and as a result dissipates heat energy.Hence it is considered as a heat dissipating device..\n\nReactance is an energy storing device and is associated with coils which are magnetic energy producing device.\n\nHence a reactance stores energy and then gives it back .\n\nImpedeance is the sum of resistance  plus reactance but reactance is 90 degrees out of phase. Hence reactance is \ndescribed as imaginary quantity where resistance is real quantity.\nResistance is real because it dissipates energy and reactance is imaginary be cause it stores energy as magnetic and does not dissipate as heat energy.\nImpedeance in a circuit folows the same circuit rules as resistance.

First of all generator generates electricity. Electricity is tapped from armature of the generator. While in electrical motor , supply is given to the armature. As far as your question is concerned since the armature is rotating while magnetic field is stationary only way to tap the supply is through brushes. Continuous wire will break .

The entire reason that every house and business and car/truck has breaker boxes is because of resistance. Current flowing where it shouldn't, and causes somehting to heat up is because of resistance!\n\nComputers....same thing. Most circuit boards have relayes that will 'trip' if a short occurs, and usually this results in things getting overheated.......because of resistance.\n\nResistance is like friction for electrons. If you rub two sticks together they get hot (resistance)....same for electrons flowing thru a wire. The electrons 'bump' into various things as they go, and it gives rise to heat to put it simply.\n\nToasters rely on resistance to work. Ever look inside when one is on? Ever see the glowing wires in there?.....resistance causes the wires to heat and get red hot! This is what 'cooks' your toast.\n\nSame for an electric oven.......electric heating in your home.\n\nDoes this help?\n\nGood luck to you!\n\n:)

You might start by contacting the power company.  If you have concerns about eletromagnetic interference, they should be willing to help you.

Wall sockets have AC voltages, so there is no positive and negative.  One of the two prongs has what is called "Hot", and the other is called "Neutral".  The Neutral is connected to ground back at a distribution center, while the Hot is 110 Volts AC (in the U.S.).  By the time it gets to your home, the Neutral is not quite ground anymore, but is still relatively safe- wheras the Hot is quite dangerous and potentially deadly.\n\nSome appliances are designed to have extra protection between the Hot and people.  For example, a light socket has the 'threads' (the easily touched part) connected to Neutral.  As another example, most appliances and the light switches disconnect the Hot when they are off.\n\nThe different sizes of the sockets prevent you from plugging an applicance in backwords.  If you did this, then the switch would disconnect the Neutral instead, and leave the Hot on- making the device less safe.

it reduces fluctuation, whether upwards of downwards. This is best to protect motorized appliances like refrigerators, computers, and other sensitive devices. There are stabilizers focused on sine waves and digital waves depending on what devices to protect. 3rd world countries would always have fluctuations of power and this is where it is mostly needed.

Not sure. I use to be an electronics Tech but that was before SMPS existed. I'm guessing you might find something on the link below:

The difference is that the pipe allows for complete current loops around the circumference of the pipe, which will generate a magnetic field in opposition to the falling magnet.  In a coil, with the ends disconnected, you won't have this happening.  You induce some emf in the coil, but it's not a closed circuit, or at least not one that can generate a magnetic field opposing the falling magnet.  You could consider small current loops induced within the wire, or around the circumference of the wire, depending on the magnet's orientation, but these will be small and weak compared to a current loop all the way around a pipe.  However, if you wire one end of the coil to the other,  you should get some Lenz's law braking of the magnet.   \n\nIt's a very clever idea for a demonstration.  I had to go set it up and test it myself with some magnet wire wound around a glass tube and a glass tube sheathed in a copper pipe, to see the effect you described.  Like I said, if you connect the coil to itself, you will see some effect, but it's not nearly as strong as the copper tube.  I think this is because the emf is induced in the coil as a whole, and not as a local loop as in the pipe, so you have a field of the same total strength, but it's not as strong locally. I think I'm going to have to play around with this some more and maybe do some actual math to figure out the full details.

They are called Surface-Mount resistors, and they look like little rectangular boxes about the size of breadcrumbs.  Of course it's hard to tell which ones are resistors since diodes and small capacitors also come in this size and style.  If you've broken one off they are hard to get back on properly.  You'll need to ask a friend who has surface mount soldering skills and an expensive soldering iron made exactly for such a task.

The non technical explanation.\nMeggers were a device used for checking the winding insulation on motors. Manufacturing technology was not what it is now with a wide variance in motor preparation, especially rewinds. Meggers put a current through the winding and measure the loss and Resistance. A lot of standard bid specifications include the megger test to be performed. It has become obsolete since manufacturing is much better and the current used can destroy a lot of electronic control components .
