  • Page 4: Introduction

    1. Introduction Due to its construction, the rotational speed of a 3-phase AC motor is directly dependent on the frequency of the voltage and the number of poles. In case of a 3PH 50Hz voltage and a 2-pole motor, the nominal speed would be 50 rps * 60 = 3000 rpm. In case of BLDC motors (brushless dc), the speed is directly dependent on the voltage applied.

    5. Safety- Precautions and Warnings This device produces dangerous electrical voltages and is used for the operation of fast spinning tools. Because of their high rotational speed, it may be dangerous in case of improper handling. For this reason, only professionally trained and qualified personnel should be allowed to work with and setup this device! Before the first commissioning can be carried out, it should be ensured that the spindle and the tool are fixed properly, to eliminate all dangers because of uncontrolled movement of...
