Title:
ELECTRONIC SPEED CONTROLLER, MOTOR ASSEMBLY AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/082526
Kind Code:
A1
Abstract:
An electronic speed controller (17), used for regulating rotational speed of a motor (13) and comprising: a controller (50), used for generating a control signal according to the operating state of the motor (13); and a driver (30), used for outputting an alternating signal for adjusting the rotational speed of the motor (13) according to the control signal generated by the controller (50). The driver (30) comprises at least one power unit which comprises a pre-driver and a semiconductor power device that is electrically connected to the pre-driver. The electronic speed controller (17) integrates the pre-driver and the semiconductor power device into the power unit, thereby increasing an anti-interference capability of the electronic speed controller (17) and reducing the size of and space occupied by the electronic speed controller (17).
