Source sentences:
text: The commutator switches power to the coils as the rotor turns, keeping the magnetic poles of the rotor from ever fully aligning with the magnetic poles of the stator field, so that the rotor never stops (as a compass needle does), but rather keeps rotating as long as power is applied.
text: Usually the armature resistance of a motor is less than 1 Ω; therefore the current through the armature would be very large when the power is applied.
text: Usually the armature resistance of a motor is low; therefore the current through the armature would be very large when the power is applied.
text: The geometry of the brushes, commutator contacts, and rotor windings are such that when power is applied, the polarities of the energized winding and the stator magnets are misaligned and the rotor will turn until it is very nearly straightened with the stator’s field magnets.
