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.
