Explain the basic operation of a DC motor
What will be an ideal response?
Voltage is applied to the motor, current flows through the windings and makes them magnetic which causes the rotor to spin. The rotor receives voltage through a set of brushes that ride on its commutator and allow current to flow through the armature. The commutator segments on the armature cause the polarity of the coils in the rotor continually change and cause the rotor to spin.
