How to find motor torque

It requires special expensive equipment. Therefore we suggest calculating it. In DC motors , electrical power (Pel) is converted to mechanical power (Pmech).

Physically, power is defined as the . 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 .

Speed of electrical motors - output power and torque.

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. From the formula above we see that . I am intending to replace that engine with the DC motor.

Merkle-Korff Gearmotor specifications.

Convert Stall Torque from in-lb to N-m. A motor turns electrical energy into mechanical energy. Calculate the Force required to . The magnetic field spins the rotor, rotating the output shaft.

Torque is the force with which the shaft spins.

Using the example figure, multiply 0. Now divide the torque by the current. To calculate the Motor Voltage Constant read the no load speed (rpm) and convert it to radians per second. Take the Rated Voltage of the motor . The desired speed range may be difficult to achieve depending on the type of application.

Generally speaking, the user can follow the below steps to choose the proper motor and driver.

Determine the motion profile and calculate acceleration, deceleration and maximum velocity required to make the. This online calculator turns power into torque and vise versa. To convert watts to another power unit, see box to right.
