The purpose of this file is to gather all the basic current data on Motors , Electronics and
Dynamometer testing of motors together.
The data presented here is relevant to new car design.
1 MOTORS:
Current thinking is, the best motor available is the Faulhaber 2232 6 Volt.
This is a 10 Watt motor with the same shaft size and mounting detail as the 2224 series
which had previously been very popular. The 2232 however has a rotor resistance that
better suits the characteristics of the typical electronics units being used , consequently its
torque at low RPM is significantly higher resulting in better acceleration and faster race
times.
Below is the graph of Torque vs RPM for both these motors.
These graphs were produced from data obtained in is the initial tests we performed to
evaluate the suitability of the then new 2232 motor.

When these results were entered into the Mathematical Simulation, predictions were that
by just changing motors from 2224 to 2232 a significant reduction in race time occurs.
Technical Data for these motors follows. These are copies of the manufacturers data
sheets.
