Electric motors in karts: a simple guide

The most important variable in these equations is the motor constant, k.  The motor constant is made up of a combination of stator size, windings, and magnetic field.  I had to keep these in mind when choosing the components for my motor to make sure it would perform well.  Torque (τ) and rotational velocity (ω) of a motor are both related to k.

k=NBLD
ω=2*V/k
τ=2*k*i

N is the number of turns of wire on each tooth of the stator, B is the remnant flux from the magnets, L is the length or thickness of the stator, and D is the diameter of the stator.  k is also related to speed and torque, where V is the voltage and i is the current through the windings.
