Product Description
Magtrol’s Cogging Test System is a stand-alone test system designed to control and measure Detent Torque, Cogging Torque and Friction Torque. The test System includes a precision geared motor, a TS Series Torque Sensor integrating a 5 000 pulses encoder. CTS 100 to CTS 102 have a built-in security clutches to avoid system overload by mishandling when not in use. The geared motor drives the MUT (Motor Under Test) at a low speed from 1 … 10 rpm (other speed available as an option), while acquiring its cogging torque related to angle position. The torque measurement covers a range up to 2 N∙m (depending on the selected torque sensor) with an accuracy of ± 0.1 mN∙m (for TS 100 – 50 mN∙m and TS 101 – 100 mN∙m). The executable software controls the system and displays acquired data. It provides accurate peak-to-peak measurement of cogging torque and displays X-Y or polar graphs as well as FFT analysis. The software allows the storage of measured data and provides comparison of performance data by overlaying up to 5 graphs. A cursor can be used to read accurate values from measurement points. Measured parameters can be saved as text file TXT. For better accuracy and function control, the software includes a zero offset adjustment routine which checks transducer signal over a complete turn (test sample MUT not connected to the system).
As a stand-alone system, the CTS only requires 100 – 240 VAC power. A USB interface allows direct connection to the PC on which the software is installed. It is mounted on a PT-25 grooved base plate on which the motor fixture can be fitted. Vertical mounting bracket are available as an option, allowing to mount the system in vertical position, which is particularly recommended for very low measuring values.
Models CTS 100 to CTS 102 can easily be scaled up or down (50, 100 or 200 mNm), simply by replacing the TS Sensor which is mounted in front of the unit. The software will recognize the torque sensor being in use and will automatically adapt its measuring range.
