Re: Spikes and CIM?
Guys,
A spike is only designed to handle 20 amps max. That is the rating on the contacts in each internal relay. When used with the compressor, you can change the fuse to a 20 breaker as the compressor start current exceeds 20 amps for a very short time.
A CIM motor on the other hand, has a stall current of 133 amps. That is the current it draws every time you apply current to it and it is not moving or everytime you are in a full throttle push with another robot and going nowhere. It will draw that current even if you put a 20 amp circuit breaker in place. Breakers do not limit current.
For FRC robots:

A. Each CIM motor and Fisher-Price motor must be connected to one and only one approved speed controller. These motors must not be connected to relay modules.
