VIBRO KIT

TECHNICAL REFERENCE MANUAL

3 Technical data

3.1 Introduction

The new VIBRO-KIT is a compact tool for simulating rotating machinery measurements. It is meant for
demonstrations or educational purposes such as in a lab or university. It provides a playground for
almost unlimited experiments.

It's made of solid aluminum. It’s built of a small electric motor with a simple control panel, two bearings,
two optical strip-tape angle sensors, two encoders and two different couplings on each side. One is rigid
and the other is made of spring.

The RPM can be controlled manually by a turn knob, or you can completely define ramps, cycles, etc.
with the built-in display.

Furthermore, an external analog voltage (or even PWM signal) can be used to control the RPM.

Functionalities:

Manual RPM control (turn knob, display)

Definable ramps (runup, coast down, hold time and multiple cycles)

RPM control by external voltage (e.g. step curve)

External PWM input

Different angle sensors (2 optical strip tape, 2 Encoders)
