About the device of the rotary tattoo machine, as well as a few tips on how to choose.
Working Principle of the Rotary Tattoo Machines
Often tattoo artists are compared with artists who use tattoo pigments instead of the usual colors, and the canvas for them is the human skin. A kind of brush is the most important tool – the tattoo machine.
The modern tattoo industry presents us with a huge number of different types of tattoo machines, which are divided into 2 main types: rotary tattoo machines and induction.
To understand how a rotary tattoo machine works, you need to compare it with an induction tattoo machine. The distinctive feature of the rotor is that it has a motor that makes up the principle of operation of the rotor tattoo machine. With its help, you can change and adjust the impact speed by reducing or increasing the output voltage on the power unit. It works by converting the rotational motion into reciprocating motion, in the process of which the needle is immersed under the skin.
Rotary tattoos machines are equipped with thin acupuncture needles, which help to easily and easily work with the skin with a high level of sensitivity. The tattoo needle with ink is submerged into the skin at a depth of approximately 2 mm and its speed can be set from 50 to 1000 beats per minute. The rotors are ideal for working with sensitive areas and are widely used by craftsmen in permanent make-up.
Powerful eccentric motors are powered by the electric network and develop tattoo needle speed in the range of 5400-11400 rpm.
Another advantage is the special needle fastening system, which prevents the risk of scarring. It provides absolute safety and sterility of the procedure.
What is the difference between a rotary tattoo machine and an induction one?
One of the main differences between a rotary tattoo machine and an induction tattoo machine is that the driving force is first converted into a rotational force, which immediately becomes progressive. Due to the work of the motor is the movement of the needle, which ensures their uniform and easy impact on the skin.
As for induction tattoos machines, their principle of operation is much more complicated. Electromagnetic coils are responsible for supplying the needles, which in turn attract and repel the steel flanks.
Types of rotor tattoos machines
-
Direkt
The complete set of this kind of tattoo machine is very simple, it is the minimum necessary set of elements for the use of the motor: the motor itself, the body, eccentric, and the lock. They do not have any principle of motion transmission, because the tattoo needle is attached to the eccentric, which is attached to the rotor. The simplicity of the mechanism determines its affordable price, as well as ease of use. In production, they do not differ, so they are developed by almost all serial manufacturers and builders.

Straightforward.
An illustrative example shows what would happen if a standard induction tattoo machine operated on the principle of a rotary one with a rotary motor at its core. The design of this type of tattoo machine is quite simple. The device is as follows: a bearing or spring is mounted on the rotor motor, which drives the connecting rod and behind it the side. The design scheme makes this tattoo machine as stable and accurate as possible, which has a significant impact on the price of this type of device.
-
Slider
The main detail that distinguishes this model from the previous ones is a small element, which is called “slide”, you can also find the name “pin” or “slider”. In this type of rotary tattoo machine eccentric or bearing is driven by this small element – slide. The presence of spring in the device allows it to move smoothly and softly, thus ensuring a stable tattoo needle stroke.
-
Handle
Recently, this type of rotary tattoo machine has become very popular among tattoo masters around the world. Pens are often chosen for their work because of their ergonomic and comfortable shape. For this purpose, they use the more complex gear. Such a model of tattoo machines works exclusively on cartridges and due to its design is very demanding and expensive in maintenance. It will perfectly create soft paint, but the induction by the quality of the lines will not replace.
-
Piston
This type of tattoo machine is very similar to the slider, but it has one notable difference – the presence of a piston. A distinctive feature is also that due to the complex design of the rotor with the help of a connecting rod drives the piston, which moves exclusively on the guide.
Advantages of Rotary Tattoo Machines
High efficiency
At the same energy consumption, the rotary tattoo machine, unlike the induction tattoo machine pushes needles with greater force, has sufficiently high speeds and turns, resulting in clearer lines.
Versatility
They are perfect for performing tattoos with a huge number of colors and techniques. One rotary tattoo machine will perfectly cope with contours, shadows, and paint.
Low noise level
It is explained by the device of this type of tattoo machine. Due to the lack of moment of impact, the tattoo machine goes smoothly without creating discomfort for the master,
Minimal injury to the skin
The machine’s rotor tattoo unit allows the wizard to adjust the impact force and stiffness, thus minimizing skin injuries.
Ergonomics and lightness
At long work, this advantage is most loved by masters, because the weight of the tattoo machine is very important for the comfort of the master.
Low vibration
Since the tattoo machine does not have a moment of impact, due to the smooth movement of the tattoo needle vibration is reduced, which makes the work of the master as comfortable as possible and will allow novice masters to avoid errors during the elaboration of contours and the smallest details.
Shortcomings of rotary tattoo machines
Less contour clarity
Despite their versatility, the rotors are still inferior to induction tattoo machines in terms of contour clarity. The smaller the needle is in the skin, the clearer the pattern will be, in this respect, the induction acts more “hard” and is better suited for this laborious work.
Higher tattoo ink consumption
Rotary tattoos machines apply a smaller amount of tattoo pigment under the skin in one application. In order to perfectly fill the color under the skin, you need to walk several times in the same place.
Stronger impact on the skin
The needle is served at right angles, so the session will be more painful for the client. The rotor is less traumatic, but it can overload the skin – especially if you often go back to past places.
It is a great waste of time
Working with a rotary tattoo machine, the master will do the work longer. You need to walk around the drawing several times, it takes more time.
Expensive repair
The practice of tattoo masters shows that rotor tattoos machines, unlike induction, wear out faster, and a serious rotor breakage can hit your budget.
