.Advantages of square bldc motor 8000rpm:


Speed Stability
Hall-effect sensors built in the BLDC motor detect the change in polarity from an N pole to an S pole as the rotor is spinning. Based on the time between state changes, the rotor's speed is determined. This information is then fed to the drive circuit to adjust the speed of the switching sequence.


High Speed Operation
Brushed and brushless DC systems provide flat torque over a wide speed range while AC motors often lose torque as speed increases.



7.Applications of brushless dc motors 48V:


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.
