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.
Toward Wider Usage in the Future
We can expect to see BLDC motors used in a wider range of
applications in the future. For example, they will probably be
widely used to drive service robots—small robots that deliver
services in fields other than manufacturing. One might think that
stepper motors would be more suitable in this type of application,
where pulses could be used to precisely control positioning. But
BLDC motors are better suited to controlling the force. And with a
stepper motor, holding the position of a structure such as a robot
arm would require a relatively large and continuous current. With a
BLDC motor, all that would be required is a current proportionate
to the external force—allowing for more power-efficient control.
BLDC motors may also be replacing simple brushed dc motors in golf
carts and mobility carts. In addition to their better efficiency,
BLDC motors can also deliver more precise control—which in turn can
further extend battery life.
BLDC motors are also ideal for drones. Their ability to deliver
precision control makes them especially suited for multirotor
drones, where the drone’s attitude is controlled by precisely
controlling the rotational speed of each rotor.
