A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

The design of different three-phase brushless DC motors and how they generate torque. How magnetics, construction, and other factors impact torque, speed, and smoothness in BLDC motors. General ...

The DC motor is widely used in the field of servo automation and robotics. The operating principle of an electric motor is based on the interaction of two magnetic fields that attract and repel each ...

Much has been written about the process of selecting motors for applications in motion control. Motor selection can be complicated. The decisions to be made include whether to employ brushless or ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
