Accurate Cogging Test System for Motor Efficiency Improvement
Applications:
Precision Motive’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 JT Series Torque Sensor integrating a 5 000 pulses encoder. JT101
to JT303 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 JT 101 – 10 mN∙m and JT 303 – 3000 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 poincs. 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).
