Hi
I got a project on PCB board. And I need a electrical engineer to assist me to find out how to make the motor give out a buzz sound. Beside its normal operation, it is capable of giving out buzz sound or/and [login to view URL] motor itself can be run on 8.4v to 11.1v Lithium polymer battery. The motor is used to turn gear sets. I need to know how to make the motor give out a buzz sound without rotating its shaft or vibration.
And I also want to know which mosfet (N or P channel) available in the market is able to fit onto my PCB board and also able to make the rotating shaft stop instantly. (Active braking or reverse polarity).
You must have knowledge in PCB circuit board and able to understand HEX, PCBDOC & SCHDOC software and files.
Sample of the motor will be mailed to the person awarded with this project.
