A brushless motor is an electric motor without carbon brushes, that is, without sliding contacts. In brushless motors, there is no electrical contact between the moving rotor and the stationary stator.

A brushless electric screwdriver is necessary:

  • When used in cleanrooms
  • When assembling sensitive or electrical components
  • In ESD environments
  • For > 500,000 screwings per year

Other arguments in favor of brushless technology:

  • Brushed technology is no longer being further developed in screwdriving technology
  • Less downtime due to time-consuming maintenance work
  • Almost no price difference between brushed and brushless technology

Lever start system:
The electric screwdriver is started by pressing the start button by hand.

Push start system:
The electric screwdriver starts by pressing the screw on the screw head.
