3. HISTORY OF BRUSHLESS DC MOTOR British scientist Michael Faraday first experimented with the idea of the electromagnetic induction motor in the early 1800's. During that time, DC Motors did not contain permanent magnets. Instead, they operated similar to Brush DC Motors today, in that they had current flowing through the windings of the motor.

DC MOTOR.
17 Back EMF When the armature winding of a dc motor starts rotating in the magnetic flux produced by the field winding, it cuts the lines of magnetic flux. Hence according to the faraday's laws of electromagnetic induction, there will be an induced emf in the armature winding. As per the Lenz's law, this induced emf acts in opposite direction to the armature supply voltage.
