Abstract
An electric industrial robot comprises a movable robot assembly (10) forming therein an airtight chamber, and an electric drive unit for driving the robot assembly. The electric drive unit comprises a plurality of motors (36-41). The respective casings (36a-41a) of the motors are disposed within the airtight chamber (30) of the robot assembly. Electric cables (57-62) connected to the motors, respectively, are led through the airtight chamber into a fixed pipe (67) connected to the robot assembly. The interior of the motors and the interior of the airtight chamber are kept at a pressure higher than an atmospheric pressure outside the robot assembly.
