Air Bearing Motor
The air bearing motor, also referred to as the
actuator
, deforms the sample by applying a shear strain to the
sample. The motor can be operated in dynamic (sinusoidal) mode, steady (constant rotational rate) mode,
or step strain and step stress mode.

Motor position and velocity feedback are recorded using a high resolution optical encoder. Dynamic
motion can be recorded down to 0.5 µrad while transient motion can be recorded down to 30 to 40 nrad.
Modular Power Supplies
The ARES-G2 uses separate power supplies, which house the electronic instrument power supplies, motor
power amplifier, the main power conductor, and a self-diagnostic display.
These stackable units are designed to sit on the floor under your lab bench, leaving more room on the top
of the bench for other uses.
The larger unit on the bottom (see the figure below) is used by the ARES-G2 test station. The smaller top
units are designed to be used by the optional environmental units such as the Forced Convection Oven
(FCO) or the Peltier Plate system.

Stackable power supplies
Multiple environmental option power supply units can be stacked on top of the test station power supply
unit for systems that have more than one environmental option.
