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 ...
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 ...
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 ...
How current-control loops in BLDC motors improve performance and efficiency while protecting against overcurrent conditions. The differences between current-control loops, field-oriented control (FOC) ...
The driver is a key factor in determining a motor’s stall performance. Temperature can affect the stall torque of brushless DC motors. Tolerances on the motor parameters can significantly impact the ...
