This value is the gear ratio of the geared motor product you selected. This value is found in the specification tables for stepping motor products. for performing the output torque calculations of an interior permanent magnet synchronous motor (IPMSM) including both permanent magnet and reluctance. If you selected a round shaft type motor (without gearhead), leave i blank or enter 1. Let's calculate the mechanical horsepower of a machine with a 150 N.m torque value and 1500 rpm speed: Power (W) 150 N.m 1500 rpm 23,563 Watts. Return to the form and enter the rotor inertia Jo and the gear ratio i of the product you have selected to calculate the torque requirement using that particular product. When we want to convert gross torque to horsepower, we need know the formula of power in Watts: Power (W) Torque (N.m) Speed (rpm) / 9.5488. (See the motor selection tips that will appear on the result window for the detail) Then, confirm the inertia ratio to be within the recommendation. Select a product based on the required torque and the required speed. Motorized arm motor sizing forms calculate the necessary Torque, Speed, Stopping Accuracy and System Inertia important when selecting a proper motor for the application.
#Motor torque calculator software#
The software will temporary calculate the acceleration torque with a load/rotor inertia ratio of 5:1. Motor power torque 9550 × motor power input speed reduction ratio use coefficient. Leave the rotor inertia Jo and the gear ratio i blank if you have not selected any motor (or geared motor) yet. J V + J C + J Dp2 ) ( D p1 / D p2 ) 2 + J Dp1 When we want to convert gross torque to horsepower, we have to know how many watts are in one horsepower for that particular type of device (e.g., in an electric motor, 1 horsepower equals 746 Watts). Inserting the values from above and solving the equation with the imputed values gives: Tim 9550-4372 6454 (N-m) Example Problem 2: Using the same process as above, first define the variables required by the formula. Tm CALCULATE CALCULATE Home Engineering Electrical DC motor armature mechanical torque (Tm) calculator- step by step calculation, formula & solved example problem to find the armature mechanical torque produced by an electrical DC motor. Is it necessary to hold the load after the motor is stopped, but not necessary to hold after the power supply is turned off? Our horsepower calculator can help you calculate power in horsepowers. Finally, calculate the Induction Motor Torque using the equation above: Tim 9550-rPrS. Is it necessary to hold the load even after the power supply is turned off? Rolling friction coefficient between wheel and floor
