Electrically powered construction machine

Abstract

An electrically powered construction machine (1) is described, comprising a body (2), at least one air-cooled electric motor (3) for driving a drive system (4) and / or a working unit (5), and an electrical power supply (6) for providing the at least one electric motor (3) with electrical energy via an air-cooled power electronics unit (7). To ensure reliable cooling of several high-performance components within a compact design, it is proposed that the cooling surfaces (3k, 7k) of the electric motor (3) and the power electronics unit (7) be arranged facing each other, with a cooling air duct (9) connected to a fan (8) being arranged between the cooling surfaces (3k, 7k) of the electric motor (3) and the power electronics unit (7).
