Dec 17, 2015· The short answer is: brushless DC (BLDC) and synchronous AC motors are similar in construction and operation. Some manufacturers and experts even group them together as similar technologies, in the category of "permanent magnet synchronous motors."
May 14, 2019· PWM varies the average voltage and current flow in the coils and so the motor's speed and torque. The chopper circuit, uses a number of MOSFETs (metaloxidesemiconductor fieldeffect transistor). A pair of MOSFETs controls one phase of the motor, so for a 3phase BLDC motor 3 pairs of MOSFETs are required (4).

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 powerefficient control.
Basically a BLDC motor can be constructed in two ways by placing the rotor outside the core and the windings in the core and another by placing the windings outside the core. In the former arrangement, the rotor magnets act as a insulator and reduce the rate of heat dissipation from the motor .
