Driving a brushless motor requires a particular sequence. For the best result, you need to close the loop so your circuit can apply the right sequence at the right time. You can figure out the timing ...

With the appropriate driver IC and microcontroller, designers can exploit the brushless motor's declining price, smaller size, lighter weight, and minimal maintenance. As recently as two years ago, ...

When making a DC brushless motor controller choice, there are several issues that have to be addressed so that the proper device is selected for a system. If the application is a simple fan or blower, ...

The A3938 is a three-phase, brushless DC motor controller. It has a high-current gate drive capability that allows driving of a wide range of power MOSFETs and can support motor supply voltages to 50 ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Having reviewed the basics of BLDC motor control in Part 1, the design effort canbegin.. The first quest is to select a microcontroller. Looking in themarketplace there are several microcontrollers ...
