# Dc Motor Speed Calculator

The dc motor is also called as the direct current motor, which converts the electrical energy into mechanical energy. The rate at which the energy is transferred is called as the mechanical power. The angular velocity is the rate of change of the displacement of the object with respect to time. The torque is a measure of force that makes the object to rotate.
Enter the rotational mechanical power and angular velocity in the dc motor speed calculator, to find the torque.

#### Formula:

Torque = P_{rot} / ω
**Where,**
P_{rot} = Rotational Mechanical Power
ω = Angular Velocity
### Example:

Calculate the speed of DC motor from the following given data:

Rotational mechanical power = 1.11 , Angular velocity = 500 rad/sec

#### Solution:

convert angular velocity of rad to RPM using

Angular velocity (ω) = 500 rad/sec * 0.00074

= 0.37 RPM

Torque = P_{rot}/ω

= 1.11 / 0.37

= 3 oz-in
