Recent research from Portescap found that brushed DC motors best fulfill the demanding requirements of humanoid robots.

DC motors are electric motors that are powered by direct current (DC), such as from a battery or DC power supply. Their commutation can be brushed or brushless. The speed of a brushed DC motor can be ...

The motor itself can be any type of DC motor. DC motors can also differ based on commutation, the means by which current direction is reversed to allow rotors to rotate continuously. Brushed DC motors ...

Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors. Maybe I will cover AC motors in a ...
