Are you here because you want to know how the sewing machine motor works? If yes, then you have set your eyes on the right content. In this presentation, we are going to explain the mechanism through which the sewing machine motor works.
Ok, without squandering any minute of our limited time, let us directly dive into it.
The composition of a sewing machine
The automated mechanisms of these machines are actually quite simple, although the machine itself seems confused, as it depends on a collection of motors, pulleys, and gears. The sewing machine is nothing but a sharp instrument. To be honest, these machines are something like vehicles. There are currently several models available that vary widely in terms of how they are operated and cost.
Howwever,the secret behind the sewing machines is that they work in a completely unexpected way, using a different kind of stitch and two completely separate threads, one from the top (through the needle) and one from below (through a coil called a bobbin) in one mounted as a shuttle designated pivotable support mounted).
The needle drives the thread through the material and frames a circle that hits a loop on the shuttle. The circle folds over the bobbin thread as the needle pulls the following thread segment through the material. The needle thus passes the thread more than once through the material to form progressive stitches. This type of programmed sewing with two threads instead of one thread is called a lockstitch.
To further help break down how this is achieved, below we look at three mechanisms that usually occur inside the motor.
Ok, let us see.
1. Needle mechanism
This is the least complex mechanism of the three. The dimming shaft drives a wheel and a crankshaft that raises and drops the needle.2. Bobbin and shuttle mechanism
Usually, the shuttle and the loop making stitches out of the needle thread have to turn relatively fast than the needle.To achieve this, the shaft turns the shuttle in a faster spins. This is employed using gears or pulleys that are usually wrapped around the wheels that can be in different sizes.
3. Feed-dog mechanism
This is another mechanism inside the sewing machine motor. The feed dog moves the fabric through the machine at a constant speed, guaranteeing the same length of stitches. It moves up and in the meantime advances, which is done by two interconnected mechanisms driven by the primary shaft.Final Verdict
This is how the sewing machine motor works. However, today’s machines accompany work in PCs and the small screen shows that guarantee smoother activity. These PCs can control various types of motors thus control how to move the needle bar, feed the dog, and tensioning circuit. Some of these machines can produce uncomplicated or increasingly tangled weave patterns because they have a fully mechanized work area that holds the erect fabric under the needle.Also read: Necchi sewing machine guide
