supports the field poles and field winding

provides a magnetic path to the main field flux

acts as a protecting cover for the whole machine

provides support to the field winding

provide slow reactance path to the main field flux

distributes the main field flux uniformly all around the periphery of the armature

they produce a magnetic field when D.C. is passed through them.

It houses the windings in the slot - made of sheet-steellaminations

is the heart of the DC motor in which the torque isdeveloped.

it produces armature flux when current is passed through them. This flux reacts with main field flux and produces rotation or torque.

it collects D.C. from brushes, converts it into A.C. and supplies to the armature windings.

it collects D.C. from brushes, converts it into A.C. and supplies to the armature windings.

the field coils or field windings are energised by a separate DC source

uses a permanent magnet to create the magnetic field required for the operation of a DC motor

are used where high starting torque is required like hoists, cranes, electrical locomotives, elevators etc

are used where constant speed and low starting torque is required like centrifugal pumps, fans, blowers, conveyers etc
