DC Motor Calculations: Calculating Torque | MICROMO

DC Motor Calculations: Calculating Torque | MICROMOSample Calculation. The motor speed under load is simply the noload speed less the reduction in speed due to the load. The proportionality constant for the relationship between motor speed and motor torque is the slope of the torque vs. speed curve, given by the motor noload speed divided by the stall torque.
