BLDC motors can be controlled, using feedback mechanisms, to delivery precisely the desired torque and rotation speed. Precision control in turn reduces energy consumption and heat generation, and—in cases where motors are battery powered—lengthens the battery life.

The main parameters to be referenced in the selection of brushless DC motor are as follows:
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.
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.
