Re: Mecanum Wheel Speed Reduction

Here's the formula for vehicle free speed at motor free speed:

V = (N*pi*D)/(720*G) feet/sec

N is the motor free speed in RPM.

G is the motor revs per wheel rev (i.e. includes gearbox and sprocket or pulley reduction)

D is the wheel diameter in inches.

A rough rule of thumb1 is to multiply V by ~80% to account for various friction forces to obtain vehicle top speed at full throttle.


1originating I believe with JVN. The actual fudge factor depends on your drivetrain design and workmanship.
