A Traction known as DC motor in simple words is a device that converts direct current(electrical energy) into mechanical energy. It’s of vital importance for the industry today, and is equally important for engineers to look into the working principle of DC motor.

The very basic construction of a Traction motor contains a current carrying armature which is connected to the supply end through commutator segments and brushes and placed within the north south poles of a permanent or an electro-magnet.

Two major parts required for the construction of dc motor, namely.

  • Stator – The static part that houses the field windings and receives the supply
  • Rotor – The rotating part that brings about the mechanical rotations.
  • Other than that there are several subsidiary parts namely the

  • Yoke of dc motor
  • Poles of dc motor
  • Field winding of dc motor
  • Armature winding of dc motor
  • Commutator of dc motor
  • Brushes of dc motor

Yoke of DC Traction Motor

The magnetic frame or the yoke of DC Traction motor made up of cast iron or steel and forms an integral part of the stator . 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 winding of the dc Traction motor.

Poles of DC Traction Motor

The magnetic poles of DC Traction motor 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.
