What is the construction of DC motor? –

30/09/2019 · Both the DC machines DC generator and DC motor have the same construction. Therefore, either machine can be used as a motor or a generator. So the following discussion about the construction of DC motor is equally valid for the construction of the DC generator. Also, we can entitle it as the construction of DC machine.

Introduction to Rotating Machines

multipole, threephase synchronous motor under construction. In a dc machine, the armature winding is found on the rotating member, referred to as the rotor. Figure shows a dcmachine rotor. As we will see, the armature winding of a dc machine consists of many coils connected together to form a closed loop. A rotating mechanical contact is used to supply current to the armature winding as ...

• DC machines can develop rated torque at all speeds from standstill (lockedrotor) to rated speed. DC machines are easier to analyze than their AC counterparts, although their construction is made rather complex by the fact that they need a commutator, which reverses the direction of currents and fluxes to produce a net torque. • DC motors are used in a wide variety of industrial drives ...
