Re: Jaguars, what can we use in FIRST 2010?
Joe,
Your response triggered something else I had forgotten. The Jaguars have a much higher switching frequency than the Victors (15kHz vs 150 Hz for the Victors). As such the inductance of the motors play into the rise times of the pulses supplied to the motor. This effect is particularly nasty at low throttle values but the effect is a more linear response of throttle command to motor speed than in the Victors. Due to the effects of the inductance, small motor pulses cannot reach full battery voltage during the pulse width. Last edited by Al Skierkiewicz : 29-01-2010 at 12:39. |
