A sprinter has a unique burst of speed
at his command, a marathon runner an astounding stamina
and a shotputter an enormous power reserve. What they all have in common, is the perfect preparation for their respective discipline.
The EC-TEC drive concept works precisely according to this principle. This means that a cordless drill
, delivered with an EC-TEC motor, will already be individually designed
from our development department and ensured to always reach the maximum performance
for every task.
EC-TEC guaranties more performance from a single battery charge.
EC-TEC does not just provide a high performance, but is also intelligent.
By way of special power electronics, that always provides only enough energy as the particular work situation requires, it makes it possible to save energy and at the same time get significantly more from one battery charge.
The inner rotor moves in close proximity to 12 magnetic poles which work together with integrated sensors to continually send information about the current position of the rotor which ensures a smooth rotation of the motor and a precise RPM regulation. Finally, the third important factor is robustness. EC-TEC works without carbon brushes and while it is working, virtually wear free, it is also constantly checking important parameters like temperature and motor speed.
Festool programmed the power electronics of the EC-TEC drive in the CARVEX so that it can reach a cut speed of just under two meters (6.5 feet) per minute.
EC-TEC is a special drive concept developed especially by Festool to achieve the highest efficiency and productivity, longest life cycle and reliability.
Therefore, Festool only applies the EC-TEC philosophy when it is clearly useful for the customer. Examples of this are the cordless T-
and now available with this drive is the new pendulum saw, the CARVEX PS 400
. Further products are already in the planning stages.
