Calculating Maximum Angle for Incline w/ Stall

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum incline angle for a vehicle powered by two motors, specifically addressing the relationship between torque and speed during stalling conditions. The formula Torque = r * F * sin(angle) is proposed to determine the maximum torque at zero speed. The conversation highlights the necessity of a clutch or torque converter to manage the speed difference between the wheels and the motor, particularly emphasizing that electric motors deliver maximum torque at zero speed. For further insights, the user is directed to a resource on vehicle performance related to slope angles and friction.

PREREQUISITES
  • Understanding of Torque calculations in physics
  • Familiarity with electric motor characteristics
  • Knowledge of clutch and torque converter functions

I want to calculate the maximum angle an object can move. So my example is a vehicle using two motors going up an incline. Do I use Torque = r * F * sin(angle) until the torque totals to a constant max torque value but with a speed of 0? I did think maybe I had to change values to equal the torque to 0, but if torque = 0 then from graphs, the speed is at a constant movement. And in the physical world, I want the speed to = 0 ideally so the object is in stalling (these are my assumptions).

I'm just not sure where I go next with this data. So any push in the right direction would be appreciated.

I have looked into torque / speed graphs, but I'm not 100% how to incorporate stall on an incline, so I assumed using the equation above would satisfy my question.

From the motor point of view, you will need a clutch or torque converter that will slip to accommodate the speed difference between the wheels and the motor. With an electric motor, there is no problem as it produces its maximum torque at zero speed.

For more info on the potential slope angle for a vehicle, but based on friction, see the section Theory»Longitudinal acceleration»Accelerating»Hill climbing at the bottom of the page on this http://hpwizard.com/car-performance.html" .
