48V Black Three Phase Brushless Motor 250W 1000 - 4000 Rpm For CNC
Machine'
BLDC motors have found wide application in various industries -
from computer hard drives to electric transport and industrial
robots. In some fields, they have almost squeezed out brushed DC
(BDC) motors. High performance and durability are among the major
advantages of a brushless DC motor. Nevertheless, it will hardly
edge out BDC motors completely as it is still a costly solution
with a complex construction and control system. A BLDC motor
controller can perform the same functions and apply similar methods
as a brushed DC motor controller. However, there are some
conceptual differences in their arrangement and implementation.
This article will shed light on the characteristics of a brushless
DC motor controller, that is how it works, how it is built, and
what it works best for.

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.
