In this webinar we will discuss using back EMF measurements to characterize & validate motors at the end of an assembly line.
When the switch is opened, the current from the battery stops flowing instantly. However, theenergyin the relay or solenoid “opposes the original change in magnetic flux”, which is now trying to collapse. Back of emf in controlling armature current voltage eqnfor dc motor isIa(V-Eb)/(Rb ...

The controller is connected to a back EMF measurement device, which measures the back EMF of the motor, and is also configured to measure motor rotational speed. The back EMF coefficient (Ke) and motor torque constant (Kt) can be calculated therefrom and the actual motor performance thereby ...

Back emf, or back electromotive force, is an electrical phenomenon that occurs in motors when the flow of current is suddenly interrupted. It is caused by the rapid collapse of the magnetic field around the motor's armature, which induces a voltage that opposes the original flow of current. ...
