The Rotary Multi-DOF Torsion Module is ideal to teach principles of robotics and torsional dynamics. You can use it to demonstrate real-world control challenges, such as the effect of flexible coupling between an actuator and a load encountered in complex industrial processes.
The Torsion module attaches to the Rotary Servo Base Unit (SRV02) for teaching 1 DOF torsional dynamics. Adding one or more (up to seven) torsion modules in series allows to expand complexity of the experiments to study 2 DOF or Multi-DOF torsional dynamics. Using this experiment, students learn to:
In addition to teaching intermediate control concepts, the Torsion Module can be used for research in various areas, including robust control and system identification.
How It Works
The Torsion Module is a rotary torsional system that consists of an instrumented bearing block, which is mounted in a cubic aluminum frame. A shaft is free to spin inside the bearing block and its angle is measured using an encoder. The shaft can be fitted with either a torsional load or a flexible coupling.
The assembly made of one Rotary Torsion module coupled to a Rotary Servo Base Unit constitutes a one Degree of Freedom (1 DOF) torsional system. The Rotary Servo Base Unit lies on its side so that its DC motor and output shaft are horizontal and able to rotate a flexible coupling attached to a rotational load. The torsional load consists of two inertial disc masses, which can be located at different anchor points along their support bar. Up to seven torsion modules can be coupled in cascade to allow for multi-dimensional control problems.
The Torsion module comes with Quanser-developed courseware for 1 DOF experiment. The workbook with exercises, together with quick start resources, a comprehensive User Manual, pre-designed controllers and a system model allow you to get your lab running faster, saving months of time typically required to develop lab materials.

Control Topics (1 & 2 DOF Torsion)
To set up your Rotary Torsion workstation, you need additional components. Quanser engineers recommend:
¹ alternatively, you can use Q8-USB, QPIDe or any equivalent NI DAQ device supported by QUARC
² only 1 DOF Torsion experiment supported
³ NI cRIO-9074, or NI cRIO-9024 with cRIO-9113 or cRIO-9114 chassis
4 NI DAQ device must be supported by Quanser RCP toolkit. Alternatively, you can use Quanser Q2-USB, Q8-USB, or QPIDe
