Title:
ELECTRONIC GOVERNOR, MOTOR CONTROL SYSTEM, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/100894
Kind Code:
A1
Abstract:
The present application relates to the technical field of unmanned aerial vehicles, and specifically relates to an electronic governor, a motor control system, and an unmanned aerial vehicle. The electronic governor comprises: a control unit used for inputting at least two control signals; at least two driving circuits, which process the two control signals outputted by the control unit and output corresponding motor driving signals to input ends of at least two motors, where each driving circuit comprises a pre-driving circuit and a power switch circuit. On the one hand, the two driving circuits can receive the control signals outputted by a same control unit and generate corresponding motor driving signals, thus driving the rotation of the corresponding motors; therefore, the degree of integration is high, and prevented is the problem of an electronic governor being oversized as a result of one control unit being able to control only one motor. On the other hand, the pre-driving circuit and the power switch circuit are integrated on a same driving circuit; therefore, relative to the prior art, the size of the electronic governor is further reduced.
