Made of insulated copper wire that is inserted into slots and protected by a fiber paper that is sometimes referred to as fish paper. The ends of the windings are physically connected to the commutator segments with wedges or steel bands.The commutator consists of several copper segments insulated from each other and the armature shaft by pieces of mica. Insulated wedge rings hold the segments in place.
FIELD ASSEMBLY
The field assembly consists of the field frame, a set of pole pieces, and field coils. The field frame is located along the inner wall of the motor housing and contains the laminated steel pole pieces on which the field coils are wound.the field coils consist of several turnsof insulated wire that fit over each pole piece.some motors have as few as two poles, while others have as many as eight..
BRUSH ASSEMBLY
The brush assembly consists of brushes and their bolders.The brushes are usually made of small blocks of graphitic carbon because of its long service life. The brush holders permit the brushes to move somewhat and utilize a spring to hold them against the commutator.
END FRAME
The end frame is the part of the motor that the armature assembly rotates in. the armature shaft,which rides on bearings,extends through one endframe and si connected to the load.Sometimes thedrive end frame is part of the unit driven by the motor.
MOTOR SPEED AND DIRECTION
Certain applications call for motors whose speed or direction are changeable.for example,a landing gear motor must be able to both retract and extend the gear while a windshield wiper motor must have variable speeds to suit changing weather conditions.certin internal or external changes need to be made in the motor design to allow these operations.
CHANGING MOTOR SPEED
A motor in which the speed is controlled is called a variable speed motor and is either a shunt or series motor. Motor speed is controlled by varying the current in the field windings.for example,when the amount of current flowing through the field windings is increased, the field strength increases, causing the armature wingdings to produce a larger counter EMF which slows the motor.conversely,when the field current is decreased, the field strength decreases, and the motor speeds up because the conter EMF is reduced.
