The Components on a Glance

Stand: The motor block can also be mounted on the stand in a perpendicular position so that the rotary pendulums can be attached.
Motor block: The shaft can be replaced by an elastic shaft which is a part of the uncertainty set.
Electronic unit: It contains the pwm amplifier and has plugs to connect the DAQ-card, the encoder card, up to 4 encoders, the motor, the power supply and allows to add an all-pass which is part of the uncertainty set.
Target computer: The target computer contains a PCI NI-6024E DAQ card, a Measurement Computing QUAD04 encoder card and a an Intel Pro/1000 GT network card.
