However, these motors have a number of disadvantages such as noise due to brush friction, generation of sparks and electrical noise, and limited life due to brush wear. They are also extremely common in hobby aircraft, including multirotors. Electrical noise, in particular, is the result of the strong sparks that tend to occur at the areas where the brushes pass over the gaps in the commutator. Brushless DC motors are quiet, lighter and have much longer lifespans. With brushed motors, the brushes deliver current through the commutator into the coils on the rotor. Others measure the back-EMF in the undriven coils to infer the rotor position, eliminating the need for separate Hall effect sensors.
