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

  • Higher Work Efficiency
    • Resistant to Voltage Drop

      The HiKOKI AC brushless motor is scarcely affected by the applied voltage, offering steady performance even when using an extension cord.

    • Constant Speed Control

      Maintaining speed under load ensures stable performance and high efficiency.

    • Optimal Airflow System

      Optimal Airflow System

      A rear fan efficiently cools the motor for more durability.

      Compatible with Engine Generators

      HiKOKI AC brushless tools work with engine generators without on-board inverters.

    • Note that not all HiKOKI AC brushless tools have the features listed above and some features are not unique to AC brushless tools. For details, refer to each product’s webpage or instruction manual.

HiKOKI AC brushless motor tools

  • Safety Consciois
    • Brake System

      The motor stops shortly after the tool is turned off, so users can put the tool down quickly and move onto other projects.

    • 0-Voltage Restart Protection

      The motor does not restart after the power has been temporarily cut off during operation to avoid accidents.

    • Kickback Protection

      When a sudden drop in motor rotation speed is detected, the motor rapidly stops to reduce the kickback.

      CAUTION
      Depending on operating conditions, the Kickback Protection System may not work or provide specified performance. Ensure that the workpiece is properly placed and supported and that the main unit is held firmly during operation. Please carefully read KICKBACK AND RELATED WARNINGS in the instruction manual.
    • Soft Start

      Start-up torque is reduced for better control.
