Direct-Current Machines • Direct-current (DC) machines are driven from a DC power supply. DC machines are the most versatile of all rotating electrical machines. Their speed may be easily adjusted in very fine increments ranging from standstill to rated speed and even above. • DC machines can develop rated torque at all speeds from standstill
DC Motors -- principles of operation - Solarbotics.net
Every DC motor has six basic parts -- axle, rotor (a.k.a., armature), stator, commutator, field magnet(s), and brushes. In most common DC motors (and all that BEAMers will see), the external magnetic field is produced by high-strength permanent magnets 1. The stator is the stationary part of the motor -- this includes the motor casing, as well ...
