So i was just thinking about the new motor limit coming with v5 since the motors are more powerful. but what if you don’t need the power of a v5 motor and a 393 is plenty. what if you could use a 393 and it count as half of a motor on your motor limit?
So there was a thread earlier last month and Paul Copioli said if you’re using V5, you’re not going to be able to use 393s at all. So I don’t think the half motor idea is going to work.
Then you would have a 16 motor robot, essentially making all the current 12 motor robots wade in comparison. (Sure, the motors will be weaker, but still, 16 motors.)
Also, it is V5 or the current system. That has been clarified several times, as discussed above.
I would rather have 12 393s running with a cortex than 16 393s running with a V5 brain. This has been mentioned several times that 393s on V5 are for low power applications only.
so will or will not 393s work with v5
They will work for low power applications. Read “worse than they do on Cortex”
The legacy ports on the V5 all run a 5V. So running a competition robot from them is not very good. But in a classroom it would probably work fine. The cortex provides around 7.2V to motors.
The motors on the cortex just receive full voltage which is as high as 8.6 at the start.
They will work, but at reduced power. The 3 wire ports on the V5 are largely there for the use of the current sensors, however they will power the 393 motors at 5 volts. This will allow places that use VEX in the classroom where they do not necessarily need full power to save some money on motors (PLTW for example, a HUGE customer for VEX Robotics). However as it has been pointed out, using 393s with V5 will NOT be legal in VEX Robotics Competitions.
