Motor stall torque calculation
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ....

V = KEώ + iR + L (di/dt) A PWM driver will increase the voltage applied to the stepper motor to keep the current and torque constant. At some speed, the power supply will not have enough voltage, and the motor current will begin to fall. The torque drops with the current. If using a higher voltage power supply, the dynamic torque remains flat. The equation of torque is given by, Where, F is force in linear direction. R is radius of the object being rotated, and θ is the angle, the force F is making with R vector. Now if we talk about a DC motor which also works on the same principle since it is also a rotational machine.

For example, if a motor has 400 ft-lbs. of torque and stalls a particular converter at 3,000rpm. We can predict the new stall speed if torque is increased to say 500 ft-lbs. This Calculator isn't perfect. It won't work if the engines have wildly different torque curve, for example.
The Torque on shaft formula is defined as the shaft's resistance to twisting. Torque is measured in degrees is calculated using Torque = Force *(Diameter of Shaft /2).

M R = Motor friction torque M L = Load torque. Assuming that a constant voltage is applied to the motor terminals, the motor velocity will be directly proportional to sum of the friction torque and the load torque. The constant of proportionality is the slope of the torque-speed curve. Motor performance is better when this slope is a smaller number.
