Yoke of DC motor.
A, dC motor 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.Yoke of DC Motor, the magnetic frame or the yoke of DC motor 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 as far as the DC motor is concerned is to commute or relay the supply current from the mains to the armature winding housed over a rotating structure through the brushes of DC motor.You're Reading a Free Preview, pages 7 to 114 are not shown in this preview.These laminated steel sheets are stacked together to form the cylindrical structure of the armature core.Other than that there are several subsidiary parts namely the.Field winding of DC motor.Brushes of DC Motor The brushes of DC motor are made with carbon or graphite structures, making sliding contact over the rotating commutator.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.Related pages DC Motor or Direct Current Motor Working slot games machine free or Operating Principle of DC Motor Construction of DC Motor Yoke Poles Armature Field Winding Commutator Brushes of DC Motor Torque Equation of DC Motor Losses in DC Machine.Hence the machine designs are made accordingly.

Field Winding of DC Motor, the field winding of DC motor are made with field coils (copper wire) wound over the slots of the pole shoes in such a manner that when field current flows through it, then adjacent poles have opposite polarity are produced.All these parts put together configures the total construction of a DC motor.So, the commutator and brush unit of the DC motor is concerned with transmitting the power from the static electrical circuit to the mechanically rotating region or the rotor.Commutator of DC motor.The brushes are used to relay the current from external circuit to the rotating commutator form where it flows into the armature winding.Your browser does not support the video tag.
