Title:
METHOD OF BRAKING PERMANENT MAGNET SYNCHRONOUS MOTORS AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/090981
Kind Code:
A1
Abstract:
A method of braking permanent magnet synchronous motors and related apparatus. The method is applied to an electronic speed regulator and comprises: receiving a signal sent by a flight controller for braking permanent magnet synchronous motors; sending a first control signal to the permanent magnet synchronous motors, the first control signal used for controlling the permanent magnet synchronous motors to reduce the rotation speeds to a predetermined range of rotation speeds in a first predetermined period of time; after the first predetermined period of time, sending a second control signal to the permanent magnet synchronous motors, the second control signal used for controlling the permanent magnet synchronous motors to stop rotating in a second predetermined period of time. The method of the present invention guarantees coincident shut-down of multiple motors and increases using experience of an unmanned aerial vehicle.
