A sealed type internal pressure explosion proof robot motor assembly. The robot has a plurality of arms pivotably connected thereto and is used in an explosive atmosphere. Each arm is formed with an airtight chamber in which an electric motor is encased. These chambers are connected to one another so as to communicate by means of sealed hoses encasing wiring therein. Air or gas of a pressure above atmospheric pressure is supplied to the chamber through the hose. The electric motor is a DC print motor.
