Curious... Anyone smoked a motor with Tetrix ptc

[Teched3]

I didn't say the main fuse from the minibot battery should be replaced with individual fuses to the motors. The thermally-protected motor feeds, repair of damaged motors, and main fuse reduction were allowed by the GDC in team updates to help protect these motors. Every other motor circuit on the robot requires power be delivered to a motor trough a main circuit breaker and then through an individual fuse or circuit breaker. The minibot should be no different just to maintain consistency, if for no other reason. I guess I can agree to disagree.

Hello Teched3

What rating and type (slow or fast-blow) of fuse did you put in series with each motor?

I was going to put one fuse in series with each motor to protect the motors during testing. If one fuse blows, there is no expectation that our Minibot continues to operate correctly (a fuse is not a current regulation device, it is a safety device). The extra fuses would be removed before the competition.

Thanks.

We used 2.5 amp fuses for testing. The power lead disconnected (one motor) on one of our test runs, and the fuse saved the other motor as the fuse blew when all the transferred to the operating motor. I believe they were standard fuses, not slow-blow. We are currently using the thermal protection leads on our current design for competition.
