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, ...

[professor churlz] wrote in to let us know his results with modifying radio control ESCs (Electronic Speed Controllers) for use in a large (250lb range) BattleBot’s drivetrain. It’s a very long and ...

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 ...

The AMT49413 can be used as part of three-phase motor drive systems with maximum supply voltages up to 50V. One feature of the devices is a charge pump regulator that provides adequate (>10V) gate ...

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 ...

Three-phase brushless motors offer many benefits including economy, reliability and high efficiency, but also exhibit poor dynamic performance. By implementing proper control algorithms (such as field ...

This fall, the SMMA Motor & Motion College will offer three motor control courses. Topics to be covered include the Basics of Brushless DC Motors, Basic Motor Theory, Operation and Application, and ...

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 ...
