Using the relationships between motor constants discussed earlier, calculate the velocity constant of the motor from the torque constant obtained above. By multiplying the velocity constant by the nominal motor voltage, obtain the theoretical no-load speed of the motor (zero torque and no-load speed) and plot it on the left vertical axis. Draw a straight line between this point and the stall torque and zero speed point on the graph. The slope of

Sep 26, 2019 · The torque equation of DC motor designs is torque = IBA_sin_θ for each turn of the motor with the electric current I in amps, magnetic field B in teslas, area outlined by the coil A in m 2 and angle perpendicular to the coil wire "theta" θ. To use the calculate torque of DC motor designs, make sure you understand how the underlying physics works.

Given a constant v m, we can plot the speed of the motor as a function of the torque it produces (in steady state). The curve is just a straight line, as illustrated below. This equation allows us to calculate the stall (or starting) torque, by plugging in n = 0. This is the maximum torque the motor can generate. Torque should be proportional to current, whether stalled or not. Measure the current at stall. Is it what you expected? It should be just the applied voltage divided by the DC resistance of the motor coils that are switched in. Also consider that there can be significant ripple on the torque over a rotation.

Horsepower to Torque Converter is an online tool used in electrical engineering to calculate how much torque will be generated according to the input power value either in horsepower or watts. Generally, horsepower is a unit for measuring the power of various electrical motors, piston engines, steam turbines etc and it is equal to 746 watts or ... Continuous Stall Torque (T cs) – This is the amount of torque that can safely be produced over an indefinite period of time under a stalled rotor condition. This value is measured with the motor mounted on an aluminum plate (6” x 6” x 1.8”) heat sink, to the maximum allowable temperature of the windings.
