Motor Controller
This is the controller: the most technical part of the kart. The controller is a completely sealed unit containing power
and logic circuitry; it is FLASH-microprocessor-based, enabling
fi
eld re-programming, and o
ff
ering numerous user set-up
options. The controller contains a triple-fail-safe system to provide a high level of safety. If the diagnostic LED
fl
ashes, or
is not illuminated, the safety circuit may have been tripped and the kart may not operate. The controller’s personality is
set with what is called a “pro
fi
le.” The pro
fi
le of the kart determines how quickly the kart accelerates, the di
ff
erent speeds
the kart can achieve, the amount of regenerative braking present, as well as the maximum amp draw of the motor. The
pro
fi
le’s parameters should only be adjusted by quali
fi
ed personnel, and the original pro
fi
le should be saved as a base to
go back to in case of problems.
Essentially, this is the brain of the kart; it takes the input from all of the other components, then tells the motor what to do.
HERE IS THE LAYOUT OF THE CONTROLLER:
(A) – PC Pak input (see description of PC Pak below).
(B) – Interconnect board cable input
(B-) – Main ground coming from battery
(B+) – Main power coming from relay/contactor
(F1) – Field coil going to motor (F1)
(F2) – Field coil going to motor (F2)
(M1) – Main motor power going to motor (A1)
(M2) – Main motor power going to motor (A2)
