Fundamentals of motor control

The rotation of the rotor magnetic field (B rot) causes a variation of the magnetic flux in the solenoid. Consequently an electromotive force facing the flux variation is generated (Lenz's law). This effect is named back electromotive force (aka BEMF) and it is proportional to the motor speed according to the formula: B sta B rot Rotation
