Brushless motor driver with speed control and reverse. Great for starting a hard drive engine or CD-ROM drive.
Buy brushless motor driver on AliExpress: ali.pub/3tzzz4
The driver supports the management of brushless motors with the connection of the windings in the "star" and "triangle". The board is powered by direct current with a voltage of 5 to 15 volts. Also on the board there is a jumper to change the direction of rotation of the motor.
To connect the engine from hdd or cd-rom, you need to find its 3 phases, which must be connected to the controller.
The controller is built on chip 11873, which is widely used to control brushless motors.
The video showed in detail how to start the engine from a hard disk and a CD-ROM drive, how to find 3 phases and output the midpoint of the engine from the HDD. I also conducted a test for the maximum speed of the motor from the hard drive.
