Kind Code:
A1
Abstract:
The embodiments of the present application relate to the technical field of unmanned aerial vehicles. Specifically, disclosed are an electronic speed control, an electric motor control system and an unmanned aerial vehicle. The electronic speed control comprises: a control unit for outputting at least two groups of switching tube drive signals; and at least two electronic speed control main circuits for receiving one group of switching tube drive signals corresponding to same, and outputting one corresponding group of electric motor drive signals according to the switching tube drive signals, wherein each electronic speed control main circuit feeds a sampling current thereof back to the control unit, so that the control unit generates, according to the sampling current, one group of switching tube drive signals corresponding to the electronic speed control main circuit, and output ends of the at least two electronic speed control main circuits are respectively connected to input ends of at least two electric motors so as to output the electric motor drive signals to the at least two electric motors to control the operation thereof. By means of the method, the embodiments of the present application can improve the integration level of an electric motor control system, reduce the occupied volume and lower the cost.
