This circuit takes advantage of the voltage drop across bridge rectifier diodes to produce a 5-position variable voltage supply to a DC fan or other small DC motor. It is not as efficient as a ...
Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.
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 ...
