Title:
MOTOR CONTROL CIRCUIT, MOTOR SYSTEM, ELECTRONIC SPEED CONTROL AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/029176
Kind Code:
A1
Abstract:
The present application relates to the technical field of unmanned aerial vehicles, and provides a motor control circuit, a motor system, an electronic speed control and an unmanned aerial vehicle; the motor control circuit comprises: a main circuit, a control unit, a power conversion circuit, a drive circuit, and an operational amplifier circuit; the main circuit comprises at least one power unit, and the at least one power unit is used to electrically connect to the motor; the drive circuit is electrically connected to the at least one power unit and the control circuit, respectively; the power conversion circuit and the operational amplifier circuit are both electrically connected to the control unit. By means of the foregoing manner, the power conversion circuit, the drive circuit and the operational amplifier circuit in the motor control circuit may be integrated into one chip such that the motor control circuit has high degree of integration, thereby reducing the volume of an electronic speed control and reducing the weight of the electronic speed control. Furthermore, by means of a parallel connection between a first power sub-unit and a second power sub-unit, the reliability of the motor control circuit in an electronic speed control is enhanced.
