3. RESULTS In this paper, the energy-saving possibilities when using a VSD in a mine auxiliary fan have been investigated. It was assumed that without any control unit, a 75-kW auxiliary ventilation fan runs continuously at full speed for 340 days per year. In any case, during a lot of that time, the motor does not need to work at maximum speed.
