three. Locate a minimal-voltage coil and use it together with a transformer (similar to Rod Elliott's strategy, but while not having to wind the coil myself). I found some 24v clock coils available at a very inexpensive cost in this article:
Would it not even be sensible to cover the exposed portion of the wire in which it can be soldered on to the electromagnet wire (and perhaps a slight portion of the electromagnet wire alone) While using the very same jacket of heat shrink tubing?
Hazard of hearth can be a secondary worry. The majority of these 120VAC coils utilize a forty AWG enamel insulated magnet wire. I haven't noticed any occasion in the enamel insulation breaking down eventually and that very small wire will probable open up up similar to a fuse in an overcurrent problem but YMMV.
The original experienced NO fuse, it's not precise, but a brief that would or else trigger a dilemma will blow open the single strand of wire, if it had been correctly sized.
Once the clock is mounted inside the casing, the device is secured that has a Lexan panel one/four″ thick. The Lexan is secured with ligature-proof/ tamper-proof fasteners.
Our anti-ligature enclosure for clocks is Exclusive in which is has 4 sloping sides so hardly any may perhaps really perfectly be looped through the clock for self-injuries.
In the event your coil has uninsulated or free wires for the finishes You may as well insulate the finishes with epoxy or liquid electrical tape. (liquid tape will insulate very well not not reinforce much). Of course, that heat gun should be enough.
By "frame", does one signify the frame of The inner clock mechanism or maybe the metallic backplate that goes onto the again with the clock's wood case?
It would also almost certainly be easier to eliminate if I at any time required to get direct entry to the coil yet again for just a long run mend.
“Sundial Time Devices has offered our firm with good service provider and merchandise for more than two a few years.
Test right here As a result, the motor is kind of substantial and it is a multi-pole smaller velocity wide range (see Photograph underneath). Although it may perhaps appear the coil is perfectly insulated from your case, the clearances are extremely tiny in addition to the slightest mishap could rapidly induce the movement and bezel to become Dwell.
We're sorry, but your Personal computer or network might be sending automatic queries. To guard our customers, we cannot method your request at the moment.
davefr explained: Here' an illustration of a coil saved with pigtails and warmth shrink and a person saved with 3M Glass cloth tape: Click to develop...
one. Maintain the coil but increase further insulation (similar to the 3M #27 Glass Cloth Tape) mentioned inside a post by davefr previously mentioned. I am undecided exactly how much This could enable, or whether the correct method to do It could be to apply read more the tape in excess of The existing wax paper insulation, or to get rid of the outdated insulation and exchange it with tape. In any event, this looks like a reasonably straightforward thing to complete.
