A Brushless DC Motor is similar to a Brushed DC Motor but as the name suggests, a BLDC doesn’t use brushes for commutation but rather they are electronically commutated In conventional Brushed DC Motors, the brushes are used to transmit the power to the rotor as they turn in a fixed magnetic field.

The principle of the working of a brushless DC motor is the mechanical torque development due to the interaction of the magnetic field produced by rotor magnets and stator coils. The brushless DC motor is driven by an electronic drive that switches the supply voltage between the stator windings as the rotor turns The rotor position is monitored by the transducer (optical or magnetic) which supplies information to the electronic controller and based on this position, the stator winding to be energized is determined. The following classification of brushless dc motors is also useful to understand the BLDC motor working principle One Phase, Onepulse Brushless DC Motor The stator of this motor has only a onephase winding which is energized by a transistor once per electrical revolution.

The basic working principle of a DC motor is based on the fact that whenever a current carrying conductor is placed inside a magnetic field, there will be mechanical force experienced by that conductor All kinds of DC motors work under this principle Hence for constructing a DC motor, it is essential to establish a magnetic field The magnetic field is established by using a magnet. Commutator (can be brushed or brushless, depending on the motor type) Field magnets (provide the magnetic field that turns an axle connected to the rotor) In practice, DC motors work based on interactions between magnetic fields produced by a rotating armature and that of the stator or fixed component A sensorless DC brushless motor controller. A brushless DC motor is essentially flipped inside out, eliminating the need for brushes to flip the electromagnetic field In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator A computer then charges the electromagnets in the stator to rotate the rotor a full 360degrees.

As the name implies, Brushless motors differ from traditional DC motors in that they do not use brushes for commutating the electromagnets Instead, it is up to the motor controller to apply, in sequence, current to each of the 3 motor windings in order to cause the rotor to spin.

A brushless DC motor (known as BLDC) is a permanent magnet synchronous electric motor which is driven by direct current (DC) electricity and it accomplishes electronically controlled commutation system (commutation is the process of producing rotational torque in the motor by changing phase currents through it at appropriate times) instead of a mechanically commutation system. The work principle of the BLDC motor is similar to that of the brushed DC motor The brushed DC motor adopts the electric brush and the commutator to realize commutation of the current in the winding On the contrary, the BLDC motor realizes commutation of the winding current in the electronic way. Definition BLDC Motor also known as Brushless DC Motor is a motoroperated without brushes to overcome certain difficulties The basic difference between a brushed one and BLDC is operating with and without brushes A normal machine operates with brushes used to either collect or send current to the commutator.

A, Brushless motor works through the the alternating electromotive force of armature coil,by the commutator with brushes for the role, so that leads from the brush end into the DC when the force of the principle EMF direction is determined by the righthand (magnetic induction line to the palm of the hand, thumb pointing to the direction of conductor movement, the other four fingers pointing is the direction of the electromotive force induced in the conductor).
