42mm 24V BLDC Motor 3 Phase 4000 Rpm With 5mm Round Shaft 25W / 26W
BLDC motors also offer high durability and low electric noise
generation, thanks to the lack of brushes. With brushed motors, the
brushes and commutator wear down as a result of continuous moving
contact, and also produce sparks where contact is made. 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. This is why BLDC motors are often considered preferable
in applications where it is important to avoid electrical noise.
We’ve seen that BLDC motors offer high efficiency and
controllability, and that they have a long operating life. So what
are they good for? Because of their efficiency and longevity, they
are widely used in devices that run continuously. They have long
been used in washing machines, air conditioners, and other consumer
electronics; and more recently, they are appearing in fans, where
their high efficiency has contributed to a significant reduction in
power consumption.

Ideal Applications for BLDC Motors
We’ve seen that BLDC motors offer high efficiency and
controllability, and that they have a long operating life. They are
widely used in devices that run continuously. They have long been
used in washing machines, air conditioners, and other consumer
electronics; and more recently, they are appearing in fans, where
their high efficiency has contributed to a significant reduction in
power consumption.
They are also being used to drive vacuum machines. In one case, a
change in the control program resulted in a large jump in
rotational speed—an example of the superlative controllability
offered by these motors.
BLDC motors are also being used to spin hard disc drives, where
their durability keeps the drives operating dependably over the
long term, while their power efficiency contributes to energy
reduction in an area where this is becoming increasingly important.
