Details

At 24V input, the performance curve summarizes speed, bus current, efficiency, and power versus output torque for sizing.

Moving to 36V shifts the operating envelope, with the same key metrics plotted against torque for quick comparison.


Thermal behavior at 24V, 120 rpm, and 6 Nm helps estimate steady-state temperature rise under continuous loading.


Point-labeled torque/time data at 36V supports benchmarking against your duty cycle at a 120 rpm test condition.
