To verify that your ship is functioning as the manufacturer said it should, you would complete a test that quantifies the true output of the engine an engine horsepower verification test. Holding torque (T) is the product of a motor's torque constant (KT) and the current (i) applied to the stator windings. 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". Calculate the motor power of the gearbox via the following formula: Motor power = torque 9550 motor power input speed reduction ratio use coefficient. A collection of really good online calculators. 11 common faults and repair methods for three-phase asynchronous motors. If you're not provided with the amount of force, you would multiply mass times acceleration to find the force, which means you would need to be given those values. m). 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). Note: if When calculating the torque through the reducergearbox, the factor of gear transmission efficiency loss should be considered. n1/n2 = 1450/1.9 = 763 (here is the choice of four-stage motor), Therefore: P1N = P1 * f1 = (500 * 1450) * 1 / (9550 * 763 * 0.85) = 0.117 (KW) so we generally choose 0.15KW speed ratio is about 763 enough to cope with. The pull-up torque may be critical for applications that needs power to go through some temporary barriers achieving working conditions. Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. Try to imagine an object which rotates around a specific point. The most common method for measuring torque and power of an engine is through a dynamometer, or dyno test. This formula is a calculation formula for the relationship between torque, power and speed commonly used in engineering. You need that ship to function at its rated horsepower capacity to ensure youre performing efficiently. Cookies are only used in the browser to improve user experience. Define the calculation method: reduction ratio = input speed and output speed. What is the function of the rectifier for brake motors?

The 9550 in your formula is probably a conversion factor for some specific unit system, and you should get rid of it. So the direction of the torque is away from the tires which is also direction you want the lug nuts to ultimately go. T unit is kg-cm, torque = 9550 * output power / output speed. Here, the torque often isn't calculated directly, but can instead be calculated in reference to the total angular acceleration, , that the object undergoes. At this point, you can talk to either a consultant, the engine manufacturer, or the propeller manufacturer to determine where the vessel performance issue is coming from, and determine how to fix it. Servo motor torque calculation formula: T = F * R * reduction ratio. In calculations, torque is represented by the Greek letter tau: . Torque is a vector quantity, meaning it has both a direction and a magnitude. Retrieved from https://www.thoughtco.com/calculating-torque-2698804. T = 9.55 * P / N, T output torque, P power, N speed, the motor load has a constant power and cross-torque points, constant torque, T constant, then P and N is proportional relationship. 4. 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. Motor power = torque 9550 Rated power's motor input speed /Ratio /service factor. It looks ugly in calculation, since it is not standard, but it works! 88, Minhe Road, Zeguo, Wenling, Zhejiang, China.
