High-Frequency technologie

(8 products found)

High-frequency electric motors operate at a higher frequency than conventional 50/60Hz-machines.
Because of the higher frequency, the motor runs much faster. This high speed is reduced with gears resulting in a high torque. This high torque ensures optimum power when drilling and sawing in concrete.
The high speed requires qualitative ball bearings that need to be cooled with water. This cooling water serves twice, besides the bearings, also the rest of the rotating parts is cooled and the motor housing can be limited in size.
Since no more air has to be drawn in for cooling, the housing can be closed and dust or cooling water can not enter the motor. This also ensures a significantly longer lifespan.
So for large sawing or drilling projects, an investment in a high-frequency machine is certainly worth considering!
