I => Input DC Current. 30 ) * Ï ). Torque - Horsepower (hp) conversion is a method of converting one unit from other and vice versa. This calculator will measure either horsepower or torque, depending on the selection made below. Measuring a static torque in a non-rotating system is usually quite easy, and done by measuring a force. The answer will be 0.00044. Power-Torque Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM) Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025. The equation of torque is given by, Where, F is force in linear direction. For example, if your engine has a torque of 350 pound-feet then the horsepower would be 333 horsepower, at 5,000 RPM. power 375hp at 5500rpm, with 6500rpm redline and 175lb-ft of torque at that redline, what would be the maximum torque (and at which RPM) if one would use the said torque curve assumption? Find a Spicer parts distributor today, or find where you can place your order now on Dana’s streamlined eCommerce platform, DanaAftermarket.com. Use the utility below for calculating the horsepower output based on torque and RPM. RPM Calculation Drive the test vehicle in the chosen acceleration gear and make a note of the exact speed at an exact RPM point, i.e. torque = rFsin(θ) r: the distance between the point of origin on the axis and where the force is applied on the piston. I would like to know what more information I would need that i could calculate theoretically to calculate how much power it would output from this. When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. To calculate the Torque (Nm), enter your Power (WATTS) and RPM below. All rights reserved. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM) Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488 Torque is a measure of the force that can cause an object to rotate about an axis. Taking the torque formula one step at a time, divide the HP of 1.6 by the RPM of 3600. Calculating motor RPM, as well as other measurements like torque, voltage and power, is essential when choosing a motor for a given application. Known variables: Horse Power and Speed in RPM Torque is the action of a force producing or tending to produce rotation. Number of teeth on driven Gear (T2) = 20.

Answer: Next multiply 0.00044 times the constant of 63,025. When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. The instrumentation can be supplied as standard transducers or in engineered solutions. Torque is a rotational force generated by the electrical system, whereas, the horsepower is an imperial unit of power equal to 745.7 watts. Calculate your Horsepower based on Torque & RPM. The torque delivered from an electrical motor producing 100 hp at speed 1000 rpm can be calculated as. Horsepower & Torque Calculator. Calculator-1. If you want to re-use it, just clean the inputs and the result by pressing the Reset button. We cannot perform the lift with this set-up, because the stall torque is smaller than . Sustainability Input the value that you wish to convert. In this case, the rotational speed which is measured in the Rotations per minute(RPM). The ⦠The calculatorâs usage is quite straightforward: just select the calculation type (power or torque), your unit system (metric or imperial), fill in the input values, and press the Calculate button. Performing a conversion from RPM to speed in a linear direction involves two steps: first convert the RPM to a standard angular velocity, and then use the formula v = Ïr to convert to linear velocity. When you choose horsepower, this calculator will measure the approximate horsepower of an engine based on the torque of the engine (measured in foot-pounds) multiplied by the RPM of the engine, divided by 5,252 (conversion between foot-pounds and horsepower). Returns & Refunds. And Driver gear is rotating with 100 rpm and 10 N-m torque. Problem: A shaft is transmitting 200 kW at 1200RPM. θ: this is theta, and it is the angle between where F occurs, and r. The formula for calculating the horsepower in a gas engine in a hybrid is the following: horsepower = torque x rpm To calculate torque from RPM, use this formula: Torque = (Motor Horsepower) x 63025 x Service Factor / RPM; What is RPM in this case? The motor power P (W) in Watt is equal to the 0.105 torque in Nm times of the speed. Horsepower to Torque Converter is an online tool used in electrical engineering to calculate how much torque will be generated according to the input power value either in horsepower or watts. Letâs take a sample problem to calculate the shaft diameter from the torque. V => Input DC Voltage. A machine rotates with speed 3000 rev/min (rpm) and consumes 5 kW. The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the RPMs. T = V x I / (2 x pi x N (rpm) / 60) N (rpm) is the speed of the motor. The power â torque calculator I attempted to reach a ⦠How to use the torque conversion calculator. Since there is no difficulty to measure rpm mechanically or using electric signals, you'll have no problems to compute or plot torque ⦠F: linear force, via the piston. Search, Identify and Order Parts - DanaAftermarket.com. How to calculate engine torque: If you know the Horse-Power of the engine, then you can use the following formula - Torque= 5252 x HP/RPM Why is engine torque important? The final Torque value of the motor is 28.16 ft-lbs of Torque. Example: Calculate the motor power rating in watts of the ac motor which has rated torque of 144Nm at 1480 rpm. These gears will cause corresponding objects to rotate slower or fast depending on the size of the gears. This is a very small number. Number of teeth on driver Gear (T1) = 40. Given the length of the moment arm, the torque can be found directly. Figuring out the Torque for Angled Forces Start with the distance of the radial vector. Measuring torque in a rotating system is considerably more difficult. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. Calculating motor speed can help you choose the right kind of motor when replacing components and help you make better repair decisions. We must either shorten the length of the lever arm, In imperial units, the Foot-pound is often used. Now if we talk about a DC motor which also works on the same principle since it is also a rotational machine. where P is power (Watt or kWatt), Ï is torque (Nm), Ï is the angular velocity (radians per second). Datumâs range of torque measurement instrumentation will provide accurate dynamic and static torque data to a high resolution. Sample Problem to calculate the shaft diameter from the torque. Why Itâs Important to Calculate RPM. The calculator accepts angular speed in RPM (rounds per minute) and the conversion to radians per second is a simple since one round is radians. Privacy Policy In order to get a realistic value, use: Your finish line MPH (from ET slip) Your finish line RPM; Your ring and pinion (gear size) Your circumference or roll out of the rear tires The rate at which an object covers distance is called time. Take maximum allowable shear stress as 70 MPa. Datumâs range of torque measurement instrumentation will provide accurate dynamic and static torque data to a high resolution. The problem with torque, however, is that it is measured in two different places: directly from the engine and to the drive wheels. This is confusing because colloquially the pound is sometimes used as a unit of mass and sometimes force. Torque = force x distance Torque Input Horse Power, hp : Input Speed, N (RPM) : Torque, T (lbs-ft) : Calculator-2.
