Nov 28, 2016· In a BLDC motor, as there are no brushes so the commutation is done by the driving algorithm in the Electronics. The main advantage is that over a period of time, due to mechanical contact in a brushed motor the commutators can undergo wear and tear, this thing is eliminated in BLDC Motor making the motor more rugged for long-term use.

There is no basic difference in the construction of a DC generator and a DC motor.. In fact, the same DC machine can be used interchangeably as a generator or as a motor. Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc motors.. DC motors are seldom used in ordinary applications because all electric supply ...

Jul 11, 2019· The very basic construction of a DC motor contains a current carrying armature, connected to the supply end through commutator segments and brushes. The armature is placed in between north pole and south pole of a permanent or an electromagnet as shown in the diagram above. As soon as we supply direct current in the armature, a mechanical force acts on it due to the …

Working Principle of DC Motor: The working principle of DC motor is very simple. We know that a current carrying coil in magnetic field starts to rotate due to the interaction of current carrying conductor and radial magnetic flux. In DC motor the magnetic field is either by a permanent magnet or produced by Field Winding. The current carrying ...
