Värinävä

Värinävä is a Finnish term referring to a device that generates or transmits mechanical vibration. The word combines värinä (vibration) with a suffix common for instruments or devices, and it appears in Finnish technical literature to describe components or systems whose primary function is to create controlled vibratory motion. The exact meaning can vary by discipline, and the term is usually clarified by context or accompanied by specifications such as frequency and amplitude.

In industrial engineering, värinävä devices include vibratory motors, shakers, and feeders. These devices convert electrical energy into mechanical vibration, typically through an eccentric mass on a motor shaft or through a separate actuator. They are used to move, sort, compact, or surface-condition materials, improve flow in hoppers, or aid screening and conveying processes.

In medical and consumer contexts, vibrating devices labeled as värinävä include handheld massagers and therapeutic tools designed to stimulate muscles, relieve stiffness, or promote relaxation. Performance is described by frequency (measured in hertz), amplitude, and mode of operation (for example continuous or pulsed).

Terminology and standards vary; värinävä is a generic term and may be replaced by more precise designations in technical documents. Safety considerations include proper mounting and isolation, electrical protection, and heat management.
