50W 24v 42mm Brushless DC Motor 4000Rpm With Driver 12V -30V 0A-8A
The key benefits of a brushless DC motor arise from its
construction features. The electronic commutation provides improved
current switching. It results in increased torque, effective speed
control over a wide range, and thus better performance of the
motor.
Using electronics instead of mechanical parts that wear makes it a
low-maintenance and long-lasting solution. In addition, the absence
of brushes leads to minimum power loss and a low level of
electromagnetic interference (EMI) and noise.
That’s why BLDC motors find wide use in devices and systems with a
long operational lifetime, including:
- industrial applications;
- electric vehicles;
- unmanned aircraft systems;
- computer equipment;
- consumer electronics;
- robotics.

Ideal Applications for BLDC Motors
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.
