Grinder’s motor has longer run time

Hitachi Power Tools has released a new addition to its growing commercial product line with the launch of model G12VE, a 4-1/2 inch AC brushless variable speed angle grinder. The grinder’s 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. Hitachi AC Brushless tools integrate electronic controllers that compensate for reduced power loss due to voltage drop. The G12VE is also designed for compatibility with a generator thanks to a compact and highly efficient inverter circuit. This circuit cleans up and modulates the electricity before it’s used in the motor providing steady, stable operation and greatly reducing the risk of damage to the internal circuits.
