Electrospindle C3140-D-DBS-P-ER20-0.7kW-12.000-24.000rpm

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 ceramic 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 12000-24000rpm motor differs from the 18000-24000rpm motors because of the lower base rpm. Because Teknomotors have a linear V/f curve, this means that this motor already has full power available at 12000rpm, resulting in higher available torque at speeds up to 18000rpm. A motor with a base rpm of 18000rpm only has 2/3 of the power available at 12000rpm and therefore has less torque available at lower speeds.
