DC Motor Questions

What is a DC motor?

A DC motor converts direct electric current into mechanical energy. Typically, DC motors are comprised of a moving rotor, fixed stator and a commutator. 

In a traditional DC motor, current is passed through wire coils to generate magnetic fields on the rotor. These electromagnetic fields interact with the permanent magnet stator fields, causing the rotor to rotate. The commutator is responsible for energising the correct coil at the right angle, ensuring the field interaction in the motor generates movement in the correct direction.
