Power measurements, on the other hand, are typically most important when quantifying the performance of the equipment driving the shaft (such as an engine). Choose the units of torque measurement that you would like to convert and click on the "Convert" button to generate the results. How to calculate the torque of the reducer? Calculating torque is a physics concept requiring an understanding of algebra, geometry, and trigonometry. As a small thank you, wed like to offer you a $30 gift card (valid at GoNift.com). The 9550 in your formula is probably a conversion factor for some specific unit system, and you should get rid of it. The fundamental equations relating torque and RPM to power is as follows: Power (Hp) = Torque (ft-lbs) x RPM / 5252 Power (kW) = Torque (Nm) x RPM / 9550 How to Measure Torque and Power of an Engine The most common method for measuring torque and power of an engine is through a dynamometer, or "dyno" test. T = r F sin . By using this service, some information may be shared with YouTube. Gear Reducer Torque = 9550 * Motor power / Rated Power motors input revolution*Ratio* gear reducer efficiency. The Locked Rotor Torque or Starting Torque is the torque an electrical motor develops when starting at zero speed. The thumb of your right hand now points in the direction of the torque vector. The formula is as follows: Knowingthe torque, the output revolution of the reducer and the usecoefficient, then how to calculate the motor power ofthe reducer. Doing so you can provide your variables in any (correct) units you like and will get a correct result. If youre ready to invest in a high-quality torque measurement system, talk to the experts at Binsfeld. While this method is straightforward for machinery that is mobile (such as a vehicle), it is not ideal in situations where machinery has already been installed. 08/25/2017 3:38 AM. In DC speed control, adjusting the armature voltage belongs to constant torque speed control (motor output torque is basically constant)In adjusting the excitation voltage is a constant power regulation (motor output power is basically constant).

The Break-down Torque is the highest torque available before the torque decreases when the machine continues to accelerate to working conditions. He is the co-author of "String Theory for Dummies.". Calculate the motor power of the gearbox via the following formula: Motor power = torque 9550 motor power input speed reduction ratio use coefficient. Reduced Voltage Soft Starters are used to limit the start current reducing the Locked Rotor Torque or Starting Torque and are common in applications which is hard to start or must be handled with care - like positive displacement pumps, cranes, elevators and similar. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Here the formula Md = 9550 x P / n to calculate. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. d. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel and diameter of driving wheel. Since torque is a rotational force, this distance is also a radius. The formula M=9550P/n can also be used for rough calculation. The above tool requires the following data for calculation: Motor-rated power in HP or kW. If you were determining the sine of the angle by hand, you would need the measurements for the opposite side and the hypotenuse side of a right triangle. "Calculating Torque." (Mandatory) The rated power and rated speed of the motor can be found on the nameplate of the motor. We don't collect information from our users. The torque of a 60 hp motor rotating at 1725 rpm can be calculated as: NEMA (National Electrical Manufacturers Association) have classified electrical motors in four different designs where torques and starting-load inertia are important criteria.
