What is EC Tec?

EC means Electronically Commutated.

The EC-TEC drive concept generates an extraordinary amount of power while consuming extremely low amounts of energy. The EC-TEC motor runs without carbon brushes and is therefore wear-free, maintenance-free and extremely sturdy.

EC-TEC works with continuous monitoring of all important parameters, such as temperature and speed. If the tool approaches a critical range, EC-TEC automatically reduces the power supply and output to protect it.

Together with the integral sensor system, 12 magnetic poles move the internal rotor within the smallest space, provide updated information on the current status of the rotor, make sure that the motor runs true and the speed is adjusted accurately.

EC-TEC represents maximum efficiency, productivity, reliability and an extended service life. EC-TEC not only provides maximum power, it also adapts to the working conditions. Special power electronics only ever generate enough energy for the relevant application, which means they save energy and increase battery charging intervals significantly.

EC-TEC is found on our Cordless Range and some of mains powered tools where it benifits from this application.
