The invention relates to the technical field of
motor control, in particular to a brushless motor electronic speed regulation circuit for an unmanned aerial vehicle and a control method of the brushless motor electronic speed regulation circuit. The brushless motor electronic speed regulation circuit comprises a
printed circuit board, a power supply module and a grid driving module. The
printed circuit board is provided with a plurality of wiring
layers which are stacked, and comprises a first power supply layer and a second power supply layer which are adjacent to each other in the vertical direction and are overlapped and aligned, and an
electrical control layer. The power supply module is arranged on the first power supply layer and the second power supply layer, the first power supply layer and the second power supply layer are electrically connected through a matrix via hole array, and the power supply module is used for being electrically connected with an external power supply and supplying power to a circuit after
processing. The grid driving module is arranged on the
electrical control layer, is powered by the power supply module and is used for outputting driving
voltage to the brushless motor, large current transmission and balanced distribution of the multi-channel
motor controller can be realized on a single
printed circuit board, and
electromagnetic interference of a power loop on a
control signal is inhibited.
