The How's as well as Whys of High Torque Clock Movements
Clock movements are the body and soul of any type of wrist watch, whether analog or digital, whether modern or antique. Clock movements are additionally known as electric motors, and their feature is to revolve the hands on a constant basis to make sure that the clock constantly depicts the right time. Therefore, we're talking about a rotating electric motor that needs to apply a particular quantity of minimal torque upon its tons, the hands, to complete its job.
Clock movements are standard according to one of the most commonly made use of applications. What this means is that the electric motor is made to offer adequate torque to cover hand weights approximately an offered limitation yet can not revolve minute hands (heavier than hr hands) evaluating greater than this.
In practice the weight limit for the most prominent clocks represents a size of about 5 inches. In other words, hands with sizes more than 5 inches will certainly in general existing as well heavy a load for the electric motor, creating the rotation to drag or even quit entirely. Hands much shorter than the limitation will certainly cause the motor no problem.
However the product made use of to make the hand additionally comes into play. Light metals such as tin or aluminum furnish a smaller tons than ones made from brass, for example. So the 5-inch criterion is a catchall amount, as well as conventional movements might have no worry turning lightweight hands longer than this.
