because of high voltage
Answer.
The purpose of a no-volt coil is to cut off the power supply from the motor if the voltage supply drops to below a safe pre-determined value.
So, alot of thin wires so that a strong magnetic flux is produced which will keep its armature attracted to the Iron point.
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
Usually for this type of installation there is a control transformer installed in the starter enclosure. The primary of the transformer is the motors line voltage and the secondary is the control voltage which is usually 120 volts. In Canada the control transformer needs fusing on the secondary side of the transformer. In the US the transformer needs fusing on the primary and secondary sides of the transformer. The secondary side of the transformer's terminals are labeled X1 and X2. The X2 lead is grounded to the starter's enclosure. From this point out the wire is then termed the circuit's neutral wire. This wire then connects to one side of the magnetic starters draw in coil. Yes, 120 volt coil would require a neutral, this could be derived from the control transformer if it has one or from an external source.

You will not be able to use the line voltage to operate the photocell directly as the photo cell is usually rated for 120 volts or in some instances 240 volts. You will need a step down transformer 480 to 120 volts. The starter will also need to have a 120 volt coil. The black and white wire of the photo cell connects to the output of the transformer and the red wire from the photocell goes to the starter coil. From the neutral terminal of the transformer a wire is taken to the other terminal on the starter coil. The transformer should be about 50 VA.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
A: A coil does store energy and this energy will be released after the current is removed is evident by a reversal of voltage across it before it collapse finally with less and less voltage <<>> Using a volt meter to ground, you would see the supply potential coil voltage on the coil end, if the return wire from the coil was open.
6 volt starter made for the vehicle. Click the link.
It will give a hotter spark when cranking if the coil gets full battery voltage while the starter is engaged.
no volt coils are used to de-energise a contactor should a situation arise in which voltage is zero
Probably not much because 6 Volts is not enough to power a 12 Volt coil
Yes. Since the coil is run at full voltage when starting 12 volts may be too much for a 6 volt ignition coil. It would be at about 8 volts when running. There is a starting resistor.
probably an old style 6 volt coil with an old-style 'lantern=battery' (6 volt) big fat square thing with the springs on top or old style 12 volt coil with like gas lawn mower key-start (completely sealed) battery /has male tabs/ on top. but coil will not hold a charge for later use.
what is the number of turns in the primary and secondary coil for 12 volt battery charger with 220 volt power supply> what is the number of turns in the primary and secondary coil for 12 volt battery charger with 220 volt power supply>
It is impossible to figure out the question.
if the vehicle it is in is a truck i would say 12volt if it is in a bus it is 24volt this is only due to the starter and the direction the starter will turn
If you've got a 6-volt starter that isn't working, I'd take it to an auto electric shop. Most of them can rebuild starters.
Nine tenths of the voltage would appear across the 200-ohm coil.
