\u00a9 2023 wikiHow, Inc. All rights reserved. Mathcad is unitaware and it considers the units, too, not just the numbers in front. Once you get past that, everything's fine: Torque is power divided by angular speed. The formula you use is from times where unit aware calculation tools were not available. m). Duringthemodel selectionprocess of speed reducer, normally several parameters will be involved includingthe reduction ratio of the reducer gearbox, the output speed of the reducer, the matching motor power and the output mode of the speed reducer. The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. Define the calculation method: reduction ratio = input speed and output speed. C. The calculation method of the gear train: reduction ratio = number of driven gears and number of driving gears (in the case of multi-stage gear reduction, the number of driven gears can be multiplied by the number of driving gears of all meshing gear sets. In imperial units the Full-load Torque can be expressed as, T = 5252 Php / nr (1), nr = rated rotational speed (rev/min, rpm), In metric units the rated torque can be expressed as, T = 9550 PkW / nr (2). b General calculation method: reduction ratio = working torque 9550 motor power motor power input revolutions work coefficient. Holding torque is a measurement of how much rotating force is required to force a stationary stepper motor shaft out of position. In torque problems, you'll typically be given the magnitude force. Among them: t-torque; 9550-constant (no need to investigate its source); p-motor power (kw); n-output speed (rev/min) The moment of inertia for a solid disc is. Try to imagine an object which rotates around a specific point. If you happen to exert any force (torque) from a distance away from the pivot point, even though the force acts along a straight line, the object will start rotating.

EDIT Just noticed that Fred had beaten me by 1 Minute and has provided the better solution. The torque of the reducer is inseparable from the motor speed, power and other factors.

Note: if When calculating the torque through the reducergearbox, the factor of gear transmission efficiency loss should be considered. You'll typically see it referred to as "angle " or "angle theta.". The 9550 in your formula is probably a conversion factor for some specific unit system, and you should get rid of it. for use in every day domestic and commercial use! The service factor is also called the using factor or safety factor; especially for users who select the gearbox, the gearboxs use factor should be determined in combination with other factors like working conditions and driven machinery. Save my name, email, and website in this browser for the next time I comment. Torque measurement can provide you the information you need to keep heavy industrial and manufacturing machinery up and running properly and efficiently. These applications will - due to browser restrictions - send data between your browser and our server. T-torque; 9550-constant (do not have to find outits source); P-motor power (KW); n-output speed (rev/min r/min) Note: if When calculating the torque through the reducer gearbox, the factor of gear transmission efficiency loss should be considered. For example: If you need the machine to drive a 100kg object,knowing the move distance R = 50mm, and the reduction ratio is 1:50, please calculate the torque of the servo motor? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. we calculate the motor power P1N. You can compare your horsepower calculation to what the manufacturer has stated to see how your ship is performing. The end result is an engine performance curve, which graphs torque, speed, and power. In the torque equation, this distance is represented by "r" for radius or radial vector.

Torque (also called moment mostly by engineers) is calculated by multiplying force and distance. Were committed to providing the world with free how-to resources, and even $1 helps us in our mission. 1. Knowingthe motor power, speed ratio and theuse coefficientand you want to know the torque of the reducer. Torque Conversion Calculator You can use this free torque conversion calculator to easily convert a range of torque measurement units including pound-force inches, Newton meters, kilogram-force centimeters, ounce-force inches, kilogram-force meters, among others. In this case, take your right hand and curl the fingers of your hand in the direction of rotation caused by the force. For example, a motor that puts out 10 lb.
