Examples of motor torque calculation

Now you can calculate the torque for this load at this speed assuming that you know efficiency of the motor. The proportionality constant for the relationship between motor speed and motor torque is the slope of the torque vs. In this example , the speed reduction caused by the 0. Merkle-Korff Gearmotor specifications.

Convert Stall Torque from in-lb to N-m.

To calculate the peak power and torque produced by an electric motor , you will need to know the following:.

The following calculators compute the various torque aspects of motors.

These equations are for estimation only, friction, windage, and other factors are not taken into consideration. Speed of electrical motors - output power and torque. Example - Torque from an Electrical Motor.

The torque delivered from an electrical motor producing 0. As you see this equation torque is the product of the force and the distance between the force and the center of rotation. So calculating load torque is determine the force in the system and the logical distance between the motor shaft and the . Physically, power is defined as the rate of doing work. Calculating Mechanical Power Requirements.

For linear motion, power is the product of force multiplied . Explaining the frequently-misunderstood relationship between power and torque.

For example , we have heard engine builders, camshaft consultants, and other technical experts ask customers:. POWER is CALCULATED from torque and RPM, by the following equation : . Using the example figure, multiply 0. The relationship between Power, Speed and Torque. The higher the speed the more power, the higher the torque the more power.

In fact the power depends on Torque multiplied by Speed. How do you calculate hydraulic motor torque ? PSI = Pressure into the motor in Pounds per Square Inch.

Disp = Motor Displacement in Cubic Inches. When performing calculations , be sure to use consistent units. Helpful tools for calculating motor loads with formulas.

It is the responsibility of the customer to specify the required motor Hp, Torque and accelerating time for his application. Fluid Motor Torque from Pressure and Displacement. Reference Citation: White Hydraulics Drive Products.

When selecting drive wheel motors for mobile vehicles, a number of factors must be taken into account to determine the maximum torque required.
