Motorized Dynaeter Test Head
Model 6610 DS Seriesmom

These test heads combine in spindle form an optical torque transducer, an optical encoder, a low inertia clutch and a synchronous drive motor.

They are available with full scale torque capacities from 1-Oz-In to 320-In-lbs.

Speed can be measured with an accuracy of I RPM and position can be measured with an accuracy of .1 degrees.

Test Head Description

The 6610 series of test heads combine in spindle form a Vibrac Optical Torque Transducer, an Optical Encoder, a Magnetic Clutch and a variable speed drive motor that is connected to the clutch through a worm drive system.

This combination of components enables these test heads to be used in both a loading mode and a driving mode.

In the loading mode, the worm drive system prevents the clutch from being back-driven and therefore it performs as a load brake.

In the driving mode, the clutch provides overload protection for the torque transducer.

General Information and Specifications

The 6610DS-SD series of test heads were designed specifically for use with Vibrac's PC 3000 series instrumentation. This combination of test heads and instrumentation can produce turn-key systems for testing stepper motors, DC motors, brushless DC motors, actuators and other similar type components.
