One of the features of the Pro-160 / 360 is the ability to measure an RPM and then display this value, convert it to MPH, and to limit the top speed if required. To allow this we need to know a] the drive wheel diameter and b] any gear ratio between the motor and the drive wheel. Once those numbers are known they can be dropped in to a spreadsheet like this speed to RPM calculator.
|Wheel speed – rpm calculator|
|Wheel diameter [inches]||5.75|
|revs per mile||3507|
|Wheel RPM at 1mph||58|
|Motor sprocket teeth||11|
|Drive shaft teeth||23|
|Physical gear ratio :1||2.09|
|Motor RPM at 1mph||122|
|Max speed required [mph]||8|
|Motor RPM at required speed||978|
|Inches in 1 mile||63360|
The spreadsheet can be downloaded here.
The Physical gear ratio and the Motor RPM at required speed numbers can then be entered into the relevant points in the Pro-160 / 360 menu.
