Dc Brushed 120watts Brushed DC Motor Motor With Speed Reducer Controller
A DC motor or direct current motor is an electrical machine that transforms electrical energy into mechanical energy by creating a magnetic field that is powered by direct current. When a DC motor is powered, a magnetic field is created in its stator. The field attracts and repels magnets on the rotor; this causes the rotor to rotate. To keep the rotor continually rotating, the commutator that is attached to brushes connected to the power source supply current to the motors wire windings.
One of the reasons DC motors are preferred over other types of motors is their ability to precision control their speed, which is a necessity for industrial machinery. DC motors are able to immediately start, stop, and reverse—an essential factor for controlling the operation of production equipment.
Brushless DC motors have a permanent magnet rotor and a coil wound stator. This design of DC motor removes the need for brushes. The benefit of a brushless DC motor is the elimination of wear and tear of brushes since very little heat is produced by the rotating magnet. The efficiency of brushless DC motors makes them more expensive.
