They also have a good weight/size to power ratio.
Such motors have little rotor inertia. The coils are attached to the stator. The commutation is
controlled by electronics. Commutation times are provided either by position sensors or by coils
Back Electromotive Force measurements.
In sensor mode, Brushless DC motors usually consist of three main parts: a Stator, a Rotor and
Hall Sensors.
2.1
Stator
A basic three phases BLDC motor Stator has three coils. In many motors the number of coils is
replicated to have a smaller torque ripple.
three elements in series, an inductance, a resistance and one back electromotive force.

The rotor in a BLDC motor consists of an even number of permanent magnets. The number of
magnetic poles in the rotor also affects the step size and torque ripple of the motor. More poles
give smaller steps and less torque ripple. The permanent magnets go from 1 to 5 pairs of poles.
In certain cases it can go up to 8 pairs of poles.( Figure 2 ).
