Step by step DC Motor Repair Services

A DC Motor Repair Services like we all know is a device that deals in the conversion of Electrical energy to mechanical energy and this is essentially brought about by two major parts required for the construction of dc motor, namely.

                 1)      Sta-tor – The static part that houses the field winding and receives the supply and

                 2)      Rotor – The rotating part that brings about the mechanical rotations.

                          Other than that there are several subsidiary parts namely the

                 3)      Yoke or casting of dc motor.

                 4)      Magnetic poles of dc motor.

                 5)      Field winding of dc motor.

                 6)      Armature winding of dc motor.

                 7)      Commentator of dc motor.

                 8)      Brushes of dc motor.

All these parts put together configures the total construction of a dc motor that has been pictorially represented in the diagram below.

Now let’s do a detailed discussion about all the essential parts of dc motor.

The magnetic frame or the yoke of dc machine made up of cast iron or steel and forms an integral part of the stator or the static part of the motor. Its main function is to form a protective covering over the inner sophisticated parts of the motor and provide support to the armature. It also supports the field system by housing the magnetic poles and field wingdings of the dc motor.

The magnetic poles are structures fitted onto the inner wall of the yoke with screws. The construction of magnetic poles basically comprises of two parts namely, the pole core and the pole shoe stacked together under hydraulic pressure and then attached to the yoke. These two structures are assigned for different purposes, the pole core is of small cross sectional area and its function is to just hold the pole shoe over the yoke, whereas the pole shoe having a relatively larger cross-sectional area spreads the flux produced over the air gap between the stator and rotor to reduce the loss due to reluctance. The pole shoe also carries slots for the field windings that produce the field flux.
