High torque movement clock hands are, put simply, those that are too hefty and/or also long for a regular motor to revolve adequately. Normally, (min) clock hands calling for a high torque movement are longer than 5 inches. The measurement is conventionally made from the facility of the installing opening to the idea.
Yet high torque clock movement min hands are readily available from suppliers as long as 18 inches. This implies that the diameter of the corresponding dial is over 3 feet throughout. Since's a huge wall surface clock!
There are, certainly, numerous, lots of clocks much less than 1 foot in diameter. Without a doubt, there are so many that many minute hands are well under 6 inches in size. Thus, the 5-inch limit for minute hands that can be turned utilizing common movements is not a serious detriment for many clockmakers.
A greater torque need calls for even more power, draining pipes the battery faster. It is consequently a design factor to consider for the maker to give the minimum amount of torque that is sufficient for the majority of situations. Normally, hands constructed from various products differ somewhat in their weights, however the five-inch limitation serves as a hassle-free criteria tipping factor.
Now, the key function of clock hands is to report the moment, with creative and stylistic declarations taking a back seat. Nevertheless, design can be used tastefully to attract the eye, helping with the focal point on the function of telling time. So style choices most definitely belong.
In addition, you desire all the parts to interact sympathetically. The hands and numerals require to contrast well against the dial history, and these aspects ought to enhance each other rather than fight. So when you have identified that you need a high torque movement for the big hands you intend to utilize, take some care in selecting both hand and dial designs that best realize your vision.
You do not need to make use of a similar design for the dial as well as hands, however, for ideal results the two designs must work. An easy way to acquire sufficient contrast is to make use of contrasting shades for the dial background and the hands. Consider using an in different ways tinted used to stop perplexing it with the minute hand.
Clock hands for high torque movements come in a number of various sizes, but there are normally just a handful of differing forms. You'll discover a straightforward taper, a thin bar, ones with arrows (with or without a reversing ruby on the other side of the installing hole), spear, gothic, as well as serpentine. One of the most usual color choice is black, but you will also locate gold, silver, white, and also vintage.
While we get on the topic we need to review pendulums for your high torque movement. The movement supplies a pendulum accessory that oscillates to and fro, and for this reason there are torque factors to consider here as well. You may or may not wish to make use of a pendulum, but if you do there fits to be a weight limitation that, if surpassed, will certainly prevent the attachment from oscillating.
This restriction is apt to be about 3 or 4 ounces. Bear this in mind if you are providing your own pendulum. But if you go get it from the parts distributor, simply make sure to obtain a pendulum developed to opt for the high torque movement you choose.
