  • Industrial robot having redundant emergency brake circuit
    Patent number: 8736219
    Abstract: The invention relates to an industrial robot having a robotic arm. The robotic arm has several axes (A1-A6) and at least one electric drive, which comprises an electric motor (7-12) and power electronics (16) actuating the electric motor (7-12) and is equipped to move the relevant axis (A1-A6). The industrial robot (1) is equipped to short-circuit the electric motor (7-12) in the event of emergency braking simultaneously by means of two independent electric current paths.
