Motor torque calculations

[mvrk33]

To calculate the torque and RPM requirements for motors in your system, we'll first need to consider the various factors affecting the motor's performance. Let's break it down step by step:

Total Torque Requirement:

Based on the load, wheel mass, friction coefficient, and required acceleration, you can calculate the total torque requirement using the formula

Total Torque =(Load×Acceleration+Friction Force)×Wheel Radius

Where the friction force can be calculated as Friction Force=Friction Coefficient×Normal Force and the normal force is the gravitational force acting on the load

Total Torque Adjustment for Efficiency:

Total Torque Required=Total Torque/Efficiency​

RPM Requirement:

Once you have the total torque requirement, you can determine the required RPM using the formula:

RPM=Required Velocity/(π×Wheel Diameter)

Total Torque and RPM for Each Motor:

Finally, divide the total torque requirement by the number of motors to get the torque per motor, and calculate the RPM per motor based on the total RPM requirement.

Torque per Motor=Total Torque Required/Number of Motors

RPM per Motor=Total RPM/Number of Motors ​
