To build and design a fully functional,
completely electric remote controlled car that
will be able to reach speeds greater than a 100
miles per hour.
David Tran





Have a control system that ensures stability at
high speeds.
Develop a power system to power all necessary
components within the car.
To design a high performance chassis and shell.
Use an onboard microcontroller to integrate all
the various systems within the car.
Integrate a RF system for communication
between a laptop and the car.

We will build a GUI
interface to control the
car.

Good torque at high
speeds
Low Turn Motor for
higher RPM
Programmable for high
efficiency at low and
high speeds
Need upwards of 10-15
thousand RPM
Possibly 2 for 4WD
Robbie Banks

The motors take three
inputs, each is a sin
wave 120 degrees out
of phase with each
other.
Robbie Banks


A three phase output
is created by turning
on and off the six
transistors at a
specific frequency and
time.
We will need to
regulate the frequency
so that we get
maximum
acceleration
