Circuit board mounted cpmponents
diode (which protects destruction reverse connection) used, necessary insert capacitor provide regenerative current route. Similarly, there nearby capacitor power supply line, will also necessary improve reliability. Hall sensor bias taken from VCC, bias, shown figure, must used. Linear drive implemented amplifying Hall sensor output applying voltage control coil. Hall effect sensor provides strong output, startup characteristics efficiency will good, then even quieter operation will achieved adjusting Hall effect sensor. This must left open unused. line from Hall sensor output Hall sensor input long, noise enter system from that line. that becomes problem, insert capacitor shown figure.
