Armature Winding In Dc Motor

The armature windings conduct ac current even on dc machines due to the commutator action which periodically reverses current direction or due to electronical commutation as in brushless dc motors.

Armature winding in dc motor. Machine armature windings the different armature coils in a dc. The armature winding of dc motor is attached to the rotor or the rotating part of the machine and as a result is subjected to altering magnetic field in the path of its rotation which directly results in magnetic losses. Some of the basic terms related to the armature winding are defined as follows. To know how armature winding is done it is essential to know the following terminologies.

The current in the armature winding is known as the armature current. Depending upon brush size this may allow access to the commutator without removing the armature from the motor. The armature can be on either the rotor rotating part or the stator stationary part depending on the type of electric machine. The difference between these two is merely due to the end connections and commutator connections of the conductor.

Armature winding armature winding is the windings in which voltage is inducedthe field winding is the winding in which the main field flux is produced when the current through the winding is passed. Of the windingthis windings are same in both dc motor and dc generator. The location of the winding depends upon the type of machine. Armature winding must be connected in series with each other by means of end connections back connection and front connection in a manner so that the generated voltages of the respective coils will aid each other in the production of the terminal emf.

However if the motor design has external brush holders you can unscrew the brush caps and remove the brushes. The armature winding is the main current carrying winding in which the electromotive force or counter emf of rotation is induced. Armature winding of dc motor.
