I am trying to get very simple Torque formula to work good but no luck (like in attachment). Example: driving a 100kg object, R=50mm, reduction ratio: 1: 50, 1) The concept of reduction ratio: the transmission ratio of the reduction device, which is a transmission ratio, refers to the instantaneous input speed and output speed in the reduction mechanism. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Divide the diameter of the output gear by the diameter of the input gear. Your email address will not be published. oz-in = Inertia based on weight; oz-in-sec = inertia based on mass; Calculation for oz-in to oz-in-sec. For tips on how to calculate torque using angular acceleration, read on! The end result is an engine performance curve, which graphs torque, speed, and power. For AC motor: the rated torque = 9550 * rated power/ rated speed; For DC motor, due to the many types of product, it is . The load is constant power, then T and N is basically the inverse relationship. The concept of power is the work done per unit time. T unit is kg-cm, torque = 9550 * output power / output speed. Different gear arrangement gearbox with vary transmission efficiency: Single-stage planetary gear:97% , two-stage planetary gear:94%, three-stage planetary gear: 91%. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Gearbox output torque refers to the actual working output torque. (Mandatory) The rated power and rated speed of the motor can be found on the nameplate of the motor. The Meaning of Torque Torque (also called moment mostly by engineers) is calculated by multiplying force and distance. Torque = 9550*output power/output speedPower (W) = RPM (rad/s) x Torque (N. m). Using your right hand and curling your fingers in the counter-clockwise direction, the thumb sticks out. The formula you use is from times where unit aware calculation tools were not available. Lets look at a scenario where both of these values are important. Binsfeld Engineering Inc.

Definition and Equations, Difference Between Independent and Dependent Variables, M.S., Mathematics Education, Indiana University, The same argument as above applies to cases of. In this situation, the ideal situation is to have the lug wrench perfectly horizontal, so that you can step on the end of it and get the maximum torque. In torque problems, you'll typically be given the magnitude force. As weve mentioned before in our article on ship performance monitoring, when you have the ability to accurately measure and monitor horsepower, there are a number of performance diagnostics you can keep up on. In calculations, torque is represented by the Greek letter tau: . Mathcad is unit aware, it will deal with your units, changing the numbers to make the values match the units you put in (and adding units to make your equations balanced.). This is good. The reduction ratio of the general reduction mechanism is marked with the actual reduction ratio, but some special reducers, such as cycloid reducers or harmonic reducers, are sometimes rounded by the rounding method without denominator. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Torque is defined as the force applied over a certain distance and is similar to work. 1. Combine that with the ships RPMs, complete the horsepower calculation, and youll have the ships actual horsepower in hand. P1N>=(T2n1)f1/(9550(n1/n2)m) can be derived from the power of the motor you want to select at this time. The above equations are particularly helpful when there is a single known force acting on an object, but there are many situations where a rotation can be caused by a force that cannot easily be measured (or perhaps many such forces). Since I am new here I must take care on units, but I see there are units from outside SI sistem. So the direction of the torque is away from the tires which is also direction you want the lug nuts to ultimately go. -feet of torque used with a gear reducer with a 10:1 gear ratio will give you 100 lb. 08/25/2017 3:38 AM. 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 = KTi In most applications, electronic drivers control stepper motors. You might also be given the torque and told to solve for the force. In physics, the torque is given as the twisting force that generate rotation of object. Using a strain gage connected to a torque telemetry system, you can see what torque the engine is actually putting out. Torque is proportional to excitation flux and armature current. Slip: S = (Ns - N) / Ns * 100%; Energy Saving Calculator. Then, when we calculate the Acceleration Torque in Torque Calculation we divide the total the total inertia by the gravity from. Power measurements, on the other hand, are typically most important when quantifying the performance of the equipment driving the shaft (such as an engine). I did not know that there is unit Hza. Torque: Md = 9550 x P / n; Calculations slip. For example, a motor that puts out 10 lb. In Metric System the H.P is ( 2 X (phi or 3.14) x N x T )/4500 where N is speed in RPM and T is Torque in Kg.M. In fact, there is nothing to discuss, there is already the formula P = Tn/9.75 .
