This device utilizes a rotary motor to drive a needle bar, creating a smooth, consistent up-and-down motion. This differs from coil-based machines which use electromagnetic coils to generate a reciprocating motion. An example of its application is the creation of fine lines and delicate shading due to its consistent power delivery and reduced vibration.
The consistent operation often leads to less trauma to the skin, potentially resulting in faster healing times. Historically, these devices evolved from simpler rotary tools used in various industries and were adapted for tattooing to offer an alternative to the traditional coil machines. This evolution has yielded a quieter, lighter, and more ergonomically designed tool, often preferred by artists for extended sessions.
