Electrospindle+Pressurized C3140-C-DBL-P-ER20-PR-AC-0.73kW-18.000-24.000rpm

The Electrospindle C3140 is the smallest design in the Electrospindle family. These motors are widely used on smaller portal milling machines and are very suitable for both milling and drilling due to the double angular contact bearings in the spindle nose. By means of a variable frequency drive (VFD) the speed can be regulated between 6000 and 24000 revolutions per minute.

This motor differs from the other Electrospindels C3140 motors by its type of cooling and bearing seal. Normal Electrospindles have fan blades at the end of the main shaft that provide cooling but can also attract dust into the motor. Electrospindles with overpressure seals, if connected to (dry) air, can allow air to flow continuously through the seals, preventing (fine) dust from entering the motor, making these motors suitable for use in a dirty/dusty environment.
