Long Lifetime and Maintenance Free - The AC brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear even in severe work environments. Besides, no carbon brush replacement is required.
Compatible with Engine Generators - Equipped with Hitachi's original, compact high efficiency inverter circuit, the demolition hammer works with an engine generator that doesn't have an on-board inverter.
Stable Performance during the Voltage Drop - The brushless motor runs cooler, and its performance isn't affected as much by voltage drop from long extension cords onsite. This vastly improves electrical efficiency.
Low vibration handle (on both the H45ME and H45MEY) - Hitachi's original, spring-type dynamic vibration absorber with a weight and two springs move in the opposite direction to the vibration direction of the main body. This results in reduced vibration and improved operating efficiency.
High Durability - The internal double-insulation construction with a very sturdy aluminium die-cast body and a plastic internal stator holder - makes the housing more rigid, significantly enhancing durability of the motor unit.
