The How's and also Whys of High Torque Clock Movements
Clock movements are the body and soul of any type of watch, whether analog or digital, whether contemporary or antique. Clock movements are additionally known as motors, and also their function is to revolve the hands on a continuous basis to ensure that the clock constantly portrays the correct time. Thus, we're discussing a rotary motor that has to apply a certain quantity of minimal torque upon its load, the hands, to accomplish its task.
Clock movements are standardized according to the most generally used applications. What this indicates is that the electric motor is developed to offer enough torque to cover hand weights as much as a given restriction yet can not rotate minute hands (larger than hour hands) considering greater than this.
In method the weight limit for the most prominent clocks represents a size of regarding 5 inches. In other words, hands with sizes higher than 5 inches will certainly in general existing as well heavy a tons for the electric motor, triggering the rotation to drag or even quit entirely. Hands shorter than the limitation will certainly create the motor no worry.
However the product utilized to make the hand likewise enters into play. Light steels such as tin or aluminum provide a smaller sized tons than ones made from brass, for example. So the 5-inch requirement is a catchall quantity, and standard movements may have not a problem turning light-weight hands longer than this.
