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. To begin calculating the value of the torque, you have to realize that there's a slightly misleading point in the above set-up. How to use the torque conversion calculator Input the value that you wish to convert. and rpm. In the engines of heavy machinery, torque is the rotating force produced by the engines shaft. YDFORCE has perfect after-sale service network. It can be understood that the higher the rotational speed, the smaller the output torque when the power P is constant. You might also be given the torque and told to solve for the force. In calculations, torque is represented by the Greek letter tau: . Using a strain gage connected to a torque telemetry system, you can see what torque the engine is actually putting out. In physics, the torque is given as the twisting force that generate rotation of object. You may simulate what engineers in former times did by dividing every variable by the unit the formula is expecting (kN and 1/min) and then at the end add the unit the formula is claiming it result to be. The other alternative would be to use a unit-aware formula which in your case simply means to divide all by 60000. Note: Your email information will be kept strictly confidential. In the torque equation, force is represented by "F.", In the torque equation, this angle is represented by the Greek letter theta, "." Calculating Torque. So the direction of the torque is away from the tires which is also direction you want the lug nuts to ultimately go. Torque, power calculation: [] = [ y] [ ] / At lower RPM (motor rotation), you can expect lower motor power at the same torque. This method is what is used by engine manufacturers to develop the specifications for a particular engine. The above tool requires the following data for calculation: Motor-rated power in HP or kW. b General calculation method: reduction ratio = working torque 9550 motor power motor power input revolutions work coefficient.

Since you know that net torque is 0, you know that the 2 forces must add up to 0, so you can construct your equation to find the missing force: For most physics problems, this distance is measured in meters. 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. The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isn't work or energy, so should just be newton-meters). As a small thank you, wed like to offer you a $30 gift card (valid at GoNift.com). In FPS system the H.P is ( 2 X (phi or 3.14) x N x T )/33,000 where N is speed in RPM and T is Torque in Lb.Ft. We don't collect information from our users. How do you calculate the torque of a gearbox? Please read AddThis Privacy for more information. In physics, the torque is given as the twisting force that generate rotation of object. This is good. We use cookies to make wikiHow great. 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. Motor power = torque 9550 Rated powers motor input speed /Ratio /service factor. The consent submitted will only be used for data processing originating from this website. Power is certain, the speed is fast, the . The magnitude of the torque is 200 Nm: For example, if the object is moving clockwise and the magnitude of the torque is 200 Nm, you would express this as -200 Nm of torque.

The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. It refers to the ratio of the instantaneous input speed to the output speed of the reduction mechanism, which is represented by the symbol "i".

\u00a9 2023 wikiHow, Inc. All rights reserved. Torque calculator is used to find the value of torque which arises from a rotating object. The unit of torque is N.m (Newton-meter). Among them: t-torque; 9550-constant (no need to investigate its source); p-motor power (kw); n-output speed (rev/min). Doing so you can provide your variables in any (correct) units you like and will get a correct result. For example, for 1.5kw motor, the output torque of 6 stages is higher than 4 stages. Among them: t-torque; 9550-constant (no need to investigate its source); p-motor power (kw); n-output speed (rev/min) The above calculation is the torque equation. Torque = force x distance. The end result is an engine performance curve, which graphs torque, speed, and power. You need that ship to function at its rated horsepower capacity to ensure youre performing efficiently.

\u00a9 2023 wikiHow, Inc. All rights reserved. Mathcad is unitaware and it considers the units, too, not just the numbers in front. In other words, Torque T (N.m) is equal to the ratio between the electrical power P (W) in watts to the acceleration. You can look at RPMs and other engine metrics, but you need to know torque to calculate horsepower and effectively evaluate engine performance. The straight line about which the object rotates is called . After strict training, the after-service engineer could offer clients the rapid maintenance service on demand. In a certain power, the higher the speed, the lower the torque, vice verse. Load torque : T LR = Nmax 9550 P LR [N . By using this service, some information may be shared with YouTube.

If a negative sign appears before the value, it simply means that the object in question is rotating clockwise. To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . Your Calculation Values Given Travelling Operation Lifting Operation Mass to be Moved m = kg Speed v = m/s (This is a common problem in these situations.) 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. The lug wrench is 0.60 m long until the end, where you apply your full weight of 900 N. What about direction? 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. The definition of gearbox transmission efficiency: refers to the ratio of the output power (or output torque) to the rated input power (or input torque multiplied by the transmission ratio) when the rated input speed reaches the rated input power (or input torque). Electric motors are operated at very different speeds and torques. The following formula: Motor power = torque9550motor power input speedspeed ratio use coefficient. The testing can be done with the equipment in place, and provides horsepower data quickly and accurately. Formula: T=9550P/n Commonly used formula in engineering: torque; power; calculation formula for the relationship between speed. Here the formula Md = 9550 x P / n to calculate. Steps to evaluate Torque of d = 9544 m, F = 9550 N Torque is defined as the force applied over a certain distance and is similar to work.

Today, Yiding Transmission will take you to understand the commonly used torque formula and the calculation of servo motor torque. reducer torque = 9550motor powermotor power input revolutionspeed ratiouse coefficient Knowingthe torque, the output revolution of the reducer and the use coefficient, then how to calculate the motor power of the reducer? For example, suppose you're told that the net torque is zero. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The Break-down Torque is the highest torque available before the torque decreases when the machine continues to accelerate to working conditions. I am using formula: Torque=9550*P(kW)/n(rpm). Different gear arrangement gearbox with vary transmission efficiency: Single-stage planetary gear:97% , two-stage planetary gear:94%, three-stage planetary gear: 91%. Servo motor torque calculation formula: T = F * R * reduction ratio. The Meaning of Torque Torque (also called moment mostly by engineers) is calculated by multiplying force and distance. Torque is an effective measurement when seeking to quantify the true mechanical torque on the driveline component, such as a driveshaft or a coupling. It looks ugly in calculation, since it is not standard, but it works! A high Starting Torque is more important for application or machines hard to start - like positive displacement pumps, cranes etc. Your email address will not be published.
