The drive sets the motor speed to what the workshop consumes. Depending on size, flow turns down to 32 to 45% of rated: the 75 kW modulates from 5.55 to 12.35 m³/min.
At fixed speed, a screw with no demand left runs unloaded and still draws 15 to 35% of its power while producing nothing, according to the US Department of Energy's Sourcebook. The drive slows the motor down instead.
IE4 class synchronous motor (IE5 on request), whose efficiency stays high at reduced speed.
