May I ask: how do you know this?

... this would equate to power savings and allow more power delivered to the motor when near stall or highly loaded. Ether's tests support this showing the spike current to be near 130 amps for the Talon and only 120 amps for the Victor 888.
I wouldn't recommend using the transient inrush current test to draw that conclusion.

Look at the curves in the speed vs torque report. The Victor888 and the Talon create virtually identical power output from the CIM at max PWM. See attached graph showing the max PWM traces from the report overlaid for Talon and Vic888.
