You have to break the motor down to the armature (bit runs through middle) and stator the coil. cut all the copper from one end of stator. stand the stator on its pre-cutt end place wood in to the center of the stator and set fire to the wood ensuring all the varnish/resin is burnt away on the stator . then with tongs or pliers remove the looped ends of copper by with drawing the strands from their respective groves

How do you ionize argon?
Argon can be ionized either through a large voltage (AC or DC) potential highenough to where the argon dielectric breaks down and allows current to flow (ionized) or by excitation through very strong high frequency RF using a coil and an HF switching power supply.
What is the pharmacy symbol ac?
AC stands for "before meals", from the Latin ante cibum.
Can you use nitrogen in AC?
All Heating, cooling, and refrigerationtechnicians use nitrogen. Nitrogen is a noble gas and prevents copper pipes from oxidizing while brazing. It is also used to check systems for leaks. Leak testing with nitrogen can save loss of expensive refrigerant which is illegal to vent to the atmosphere. It's all so a dry gas containing almost no moisture so it can help to purge moisture from system that contains moisture. That being said, nitrogen can not be used in a operational systems. Home AC systems and refrigeration systems can not use nitrogen to cool. It will damage the compressor. Also onlylicensed techs should work on AC systems.
Why rotor of an induction motor has slots around periphery filled with copper or aluminium?
The slots in the rotor of an induction motor are filled with copper or aluminum because those copper or aluminum filled slots are conductors. They constitute multiple one-turn transformers, setting up an induced magnetic field, induced from the field windings, that creates a differential magnetic flux, i.e. a torque, that causes the rotor to turn.This has little to do with the fact that the field windings are pulsing from the AC current, because the rotor "windings" are pulsing in turn - what is happening is that the rotor and field "windings" attract or repel each other as a function of their distance from each other, which is related to slippage induced by torque.
What is a hectogeneous mixture?
a hectogeneous mixture is a very dangerous chemical. its formula is: A+B=AB, AB+C=AC+B,AB+CD=AC+BD.
How do you connect a diode across a ac coil?
You mean ac coil, the secondary coil, of a transformer? Then for the purpose of rectification, that is , for changing ac into dc, a diode is connected in series with the secondary coil of the transformer.
What is the ac coil in home ac units?
The coil are responsible for transferring of cool air trough the unit
How do you find where the leak is in central ac unit?
Check all the copper lines ,the evap coil and condenser coil with soapy water assuming there is still pressure in the system. Also spray the service valves. Watch for bubbles
How do you pump down a home central AC unit if you need to clean the coil and don't want to lose all the freon?
You do not need to pump the system down just to clean the coil unless you are planning to remove the coil completely from the unit.
If the AC has an outside line that is freezing then how do you check to see if the coil needs to be cleaned and is the coil inside?
The coil is inside. Check to see if the filter is dirty as well. To clean the coil you must remove the front panel to the evap coil. If you have a flat coil you must slide the coil out to clean it. If you have an A coil, take off the plate on the front of the coil and you should be able to visually inspect the coil. It is important that you do not mash the dirt into the coil fins.
What are the two ways to magnetize a magnet?
thermal - heat the magnet above the Curie Point temperature for the material it is made ofelectromagnetic - use a degaussing coil (a coil driven by AC to keep reversing the field of the magnet), slowly remove the coil from the vicinity of the magnet before turning the power off to the coil
How do you pump down an ac system to clean the evaporator coil?
Call an AC contractor
When recovery recycling equipment is used to remove refrigerant from a mobile ac system mow much lubricant will be removed during evacuation?
Generally very little, if any
What is coil pitch?
The distance between the two sides of an individual coil of and AC armature winding id termed the coil pitch.
What is moving coil voltmeter?
mic or moving iron coil is instrument type works on ac and dc
Can a 12vac coil be operated by 24vdc?
no, in an ac circuit the coil provides impedance but the DC coil needs some resistance to limit the current
Copper pipe freeze AC Unit?
An ac unit that has copper pipes can freeze up just as other pipes can freeze up. Once the unit freezes, you need to turn them off.
