Hitachi Power Tools released a new addition to its growing commercial product line with the launch of a 4-1/2 inch AC Brushless Variable Speed Angle Grinder- model G12VE.
Hitachi’s AC Brushless motor is more efficient; leading to longer run time, increased power and extended durability with essentially no maintenance. Eliminating the need for carbon brushes means freedom from issues with the motor armature burning out, and experiencing layer shorts or commutator wear in severe environments. Also, brush wear and resulting armature damage from lack of maintenance is the most common service issue. This is completely eliminated by the Brushless motor resulting in more uninterrupted run times.
Additionally, Hitachi AC Brushless tools integrate electronic controllers that compensate for reduced power loss due to voltage drop. The G12VE AC Brushless Grinder is also designed for compatibility with a generator thanks to Hitachi’s compact and highly efficient inverter circuit. This circuit cleans up and modulates the electricity before it is used in the motor providing steady, stable operation and greatly reducing the risk of damage to the internal circuits.
