Exactly How to Fit Large Clock Hands

Large clock hands are those that are longer than around 7 inches (talking the minute hand, not the hour hand). The reason big clock hands are so marked is that sizes above that cutoff length consider excessive for a conventional motor to rotate. In other words, the typical torque is insufficient, calling for the developer of the watch to get a high-torque movement rather.

Large clock hands are theoretically unlimited in length, but practically talking you will not see any longer than eighteen inches, suggesting that the matching clock would go to the very least a backyard in size. Even then, the likeliest application for such a watch would certainly be something placed straight to the wall (using the wall as the dial, in a manner of speaking) without being enclosed in an instance.

Manufacturers have to tune to the pleasant area on the market, and for clocks that implies diameters ranging from a few inches to about ten to twelve inches. Therefore, clock movements (or electric motors) are supplied with simply enough power to revolve any and all hands falling in this range. This permits the manufacturer to make simply 2 versions of each motion, one with basic torque as well as one with high torque.
