(PDF) Construction of Mathematical Model of DC
The construction of the DC servo motor mechanism is signi ficant to EWC for dynamic response. Besides, the system has to model with load, sensor, and controlling unit.Also, we can entitle it as the construction of DC machine. A DC motor or machine consists of two windings namely field winding and armature winding. The field winding is stationary and the armature winding can rotate. The field winding produces a magnetic flux in the air gap between the armature and field windings and the armature is placed inConstruction of DC Motor Machine Your Electrical Guide

If the machine converts mechanical energy into DC electrical energy, then it is known as a DC generator. Both DC motor and DC generator have the similar construction. A typical DC machine consists of the following major parts −. Yoke or Frame. Armature. Field System. Commutator.The working of the PMDC machines is similar to the DC shunt motors except the fact that the stator fields are replaced by the permanent magnets to provide a necessary flux by which the motor operate. Because of the less interaction of the armature field with the main field, the motors experience a linear speed—torque characteristics.Design and Analysis of a Permanent Magnet DC Motor

DC Generator Parts, Working, EMF Equation, Types,
E.M.F Equation of DC generator. The emf equation of the DC generator is given by the equation: \ (\begin {array} {l}E_g=\frac {P\phi ZN} {60 A}\end {array} \) where. Z is the total number of armature conductor. P is the number of poles in a generator. A is the number of parallel lanes within the armature. N is the rotation of armature in r.p.m.The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc generator can be run as a dc motor and vice-versa. In this article, we will explain the construction of dc machine in detail. Read: Working of DC MotorConstruction of DC Machine (Generator & Motor)

What is a DC Machine? Basic structure & Equivalent circuit
Basic Structure of Electrical Machines. The rotating electrical or DC machine has mainly two parts; one is Stator, and another one is Rotar. The stator and rotor are separated from each other by an air gap. The stator is the outer frame of the machine and is immovable. The rotor is free to move and is the inner part of the machine.Mathematical model of a DC motors DC (Direct Current) or Unidirectional motors belong to rotary electric machines (electric motors and electric generators) in which the electric power is converted into the mechanical energy of rotational motion. They belong to double-coils systems because they have two coils, one on the stator and one on the rotor. DC motors Basic characteristics and mathematical model
