In practice, the crystal becomes a tiny battery with a positive charge on one side and a negative charge on the other side current flows if we connect the two sides to make a circuit. Piezoelectricity (also called the piezoelectric effect) is the appearance of an electrical potential (a voltage, in other words) on the sides of a crystal when you subject it to mechanical stress (by squeezing it). The scientific definition of piezoelectricity is as follows:
The reverse is also true: if electricity is passed through Quartz, it will vibrate back and forth. This piezoelectric effect appears when certain crystals are pressed (in our case, Quartz), it makes electricity circulate inside these crystals. The movement of the rotor is then transmitted to the gears, which makes the quartz mechanism work.īonus: If you mount a stator upside down on a clock or watch, it will run upside down.

Then an electric current is sent in the opposite direction to reverse the polarity in the stator, which will make the rotor make a full rotation. We will then introduce an electric current into the coil, which will create a magnetic current in the stator resulting in half a rotation of the rotor. The stepper motor works on this principle! First, the rotor is magnetized. The reverse also works on the same principle, i.e., inducing an electric current in a coil will have an electric current. When a magnet is rotated in a cylinder, an electric current is produced. Marius Lavet is the inventor of the stepper motor in 1936, and this motor is made up of : The chip, this time, will send an electric pulse to a coil belonging to the stepper motor. As with the digital display, the battery will send a pulse to the Quartz, which will make it vibrate and send it to the chip. This chip will then decode all the vibrations received and tell the screen to increment the display by one sound every second and then by one minute every 60 seconds.įor the analog display, this is a little longer and more complex.
This pulse will create vibrations that are transmitted to the chip installed in the mechanism. The power source is the battery, which will send a pulse to the Quartz. It is straightforward to operate a clock or watch with a digital display using the properties of Quartz. How it works and how it is used in watchmaking also depends on the display mode, digital or analog. To achieve this coveted frequency, the Quartz is cut into a lamella and then placed in a tin tube to protect it. This well-calibrated frequency lasts precisely one second, so watchmakers then quickly use it to design accurate clocks. The operation of a mechanism using a quartz movement is very simple: Quartz, when electrically stimulated, starts to oscillate at a precise frequency due to its piezoelectric properties. To understand to what extent this quartz movement has revolutionized the world, we will see in this article:
Turning our lives upside down, it was finally possible to have the exact time in our daily lives. The Quartz brought a precision unmatched in the history of time "capture" and display the quartz movement has caused a revolution in the watch and clock industry.
