92w 36v 4000rpm 67mm Brushless Dc Motor 57mm bldc motor
The main parameters to be referenced in the selection of brushless
DC motor are as follows:
Speed: this is the required speed, which can be determined
according to the speed trapezoidal curve of the motor, usually 10%
margin should be left in the calculation.
Maximum torque: this can be obtained by adding the load torque,
moment of inertia and friction. In addition, additional factors
such as air gap air resistance influence the maximum torque.
Square modulus torque: can be approximately considered as the
continuous output torque required for practical application,
determined by many factors: maximum torque, load torque, moment of
inertia, acceleration, deceleration, and running time, etc.

Advantages of 4000rpm bldc motor:
A BLDC motor with three coils on the stator will have six
electrical wires (two to each coil) extending from these coils. In
most implementations three of these wires will be connected
internally, with the three remaining wires extending from the motor
body (in contrast to the two wires extending from the brushed motor
described earlier). Wiring in the BLDC motor case is more
complicated than simply connecting the power cell’s positive and
negative terminals; we will look more closely at how these motors
work in the second session of this series. Below, we conclude by
looking at the advantages of by BLDC motors.
Applications of brushless dc motor:
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.
