Significance of a Back EMF in DC Motors!

The brushless DC motor is getting popular because, as its name suggests, it has several advantages compared to the brushed dc motor with wear-prone brushes. BLDC hub motor controller increases the device's durability. A BLDC motor may also be made lighter and smaller than a brush type while producing the same amount of power, making it appropriate for situations where space is limited. Alternative arrangements are needed to signal the relative positions of the component elements to ease motor control because the stator and rotor of the BLDC motor have no mechanical or electrical contact. BLDC motors accomplish this in one of two ways: by using Hall sensors or detecting back EMF. ...
