Separately Excited DC Motor | Electronics Tutorial

Like other DC motors, these motors also have both stator and rotor. Stator refers to the static part of motor, which consists of the field windings. And the rotor is the moving armature which contains armature windings or coils. Separately excited dc motor has field coils similar to that of shunt wound dc motor. The name suggests the construction of this type of motor. Usually, in other DC ...

Brushless DC Motor - Construction, Working Principle and ...

What is a Brushless DC or BLDC Motor? A Brushless DC Motor, BLDC accomplishes commutation electronically using rotor position feedback to determine when to switch the current. The BLDC motor is electrically commutated by power switches instead of brushes. The structure of Brushless DC Motor, BLDC is shown in figure below. In simple words, a […]

Working Principle of a DC Motor - Circuit Globe

Working Principle of a DC Motor The DC motor is the device which converts the direct current into the mechanical work. It works on the principle of Lorentz Law, which states that "the current carrying conductor placed in a magnetic and electric field experience a force".

Basic construction and working of a DC Generator ...

Thus, a DC generator or a DC motor can be broadly termed as a DC machine. These basic constructional details are also valid for the construction of a DC motor . Hence, let's call this point as construction of a DC machine instead of just 'construction of a dc generator'.
