For a D.C motor it is the field windings which must always be in series with the armature windings.
the armature current is brought thru the interpole winding near the brushes this shifts the electrical null to reduce arcing with heavy loads there were arrangements with small motors to shift the brush holder rings but the interpole has no moving parts and works under all loading conditions
The series winding takes the full load current of the generator. So it require only a few turns to produce the required magnetic field and so the resistance is lower.
The lap winding is used in dc generators designed for high-current application
The motor needs the current and magnetic flux to create motion The magnetic field is created by field winding where as armature carries the current resulting into the rotation of armature
Both lap winding and wave winding are found in the use of DC generators. The main difference is as follows: lap winding is high current, low voltage, and wave winding is low current, high voltage.
the armature current is brought thru the interpole winding near the brushes this shifts the electrical null to reduce arcing with heavy loads there were arrangements with small motors to shift the brush holder rings but the interpole has no moving parts and works under all loading conditions
compensating winding is used for equal load sharing of two generators running in parallel. while interpole winding is used to minimise the effect of armature reaction by supporting the main field.
The series winding takes the full load current of the generator. So it require only a few turns to produce the required magnetic field and so the resistance is lower.
PMDC-Permanent Magnet DC motor is a DC machine where the Permanent Magnets form the stator of the machine instead of conventional Field winding. It works on the same principle of electromagnetic induction.
dc generator is mechanical energy into convert electrical energy which used in machine part of stator in a out part & rioter is inner part and voltage induced armature winding and current pass is Field winding it is magnetic flux generate
To limit the starting current, which can be significantly larger than the running current -large enough to overheat the machine's winding and , possibly, causing insulation failure.
For winding coil.
Dc voltage level should not exceed the current carrying capacity of the winding. since winding resistance is very small. We need to be careful in giving the dc voltage to transformer winding.
