AC Brushless Motor

Lighter. Easier to Use. The HiKOKI AC brushless motor is more compact and more lightweight than conventional motors.
  • For instance, if you compare the motors of the WR16SE brushless impact wrench and the WR16SA brushed impact wrench…

    31mm Shorter
    340g Lighter (50%)
  • Brushed Motor Overall length 124mm
    →
    AC Brushless Motor Overall length 93mm
  • Brushed Motor Diameter 62mm
    →
    AC Brushless Motor Diameter 45mm
HiKOKI AC Brushless Tool are Compact with a smaller Control Circuit, Smart with Motor Temperature Sensor to Prevent the Motor from Overheating
  • Conventional Control Circuit: width 90mm, height 60mm
    →
    Capacitor-less Circuit: width 70mm, height 35mm
  • Longer Life and More Economical

    The brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear.

    No Carbon Brush Replacement Means Less Maintenance and Less Overall Cost. No Commutators, No Moter Winding
