Indagine sul driver del motore CC brushless Esc-30A

In the field of electronic experimentation, one frequently faces difficulties and successes in the search of knowledge and control. One such endeavor uses small devices with a microcontroller unit combined with half bridges to control motor operations using ESC-30A Brushless DC motor drivers.

Starting with a 12V DC source, the first steps in using the ESC-30A are to power it bearing in mind the delicate transistor threshold of roughly 20V to avoid possible damage. The driver must be kicked starting with a precise “low throttle” signal—a quick pulse at 400Hz with a 1-ms pulse width proving 12V BLDC Motor Driver successful.

Later moves to start the motor mean widening the pulse width beyond one minute, up to two minutes. Especially, trying a 2-minute pulse during the driver’s power-up phase produces bad effects. Usually featuring three pins—Red, Black, and White—White is the control signal; Black is the ground; Red denotes power input. Fascinating;
