WebTorque Depending on the subject of study, torque is also known as moment, moment of force, rotating force, or turning effect. Torque is the rotational analog of linear force. It denotes a force’s ability to cause a change in the rotational motion of a body. Torque has the dimension of force times distance. WebThe torque exerted then produces a change in angular momentum which is perpendicular to that angular momentum, causing the magnetic moment to precess around the direction of the magnetic field rather than settle down in the direction of the magnetic field. This is called Larmor precession.

WebThe back EMF of DC motor is mathematically expressed as; Putting the value of back emf (E b) from equation (8) in equation (7),we get the torque equation of DC motor. The mechanical torque developed by DC motor can be calculated by subtracting the mechanical loss from the gross torque. T m is also called shaft torque (T sh) of the DC motor.
