Abstract: The present application relates to the field of unmanned aerial vehicle (UAV) technologies, and provides a motor control system and a UAV. The motor control system includes a control unit, a first inverter electrically connected to the control unit, a second inverter electrically connected to the control unit, a first motor electrically connected to the first inverter and a second motor electrically connected to the second inverter. According to the foregoing manner, two inverters in the motor control system are electrically connected to one control unit. Therefore, the control unit can control running of two motors, thereby reducing the volume of a hardware circuit board having the motor control system and reducing the weight.

Abstract: Implementations of the present application relate to a starting method and apparatus for a permanent magnet synchronous motor, a power system, and an unmanned aerial vehicle (UAV). The method includes: obtaining a current motor rotational speed and motor position information of the permanent magnet synchronous motor; determining whether the current motor rotational speed is less than a preset minimum rotational speed, and if the current motor rotational speed is less than the preset minimum rotational speed, using the preset minimum rotational speed as a feedback rotational speed; otherwise, using the current motor rotational speed as a feedback rotational speed; and performing closed-loop control on the permanent magnet synchronous motor according to the feedback rotational speed and the motor position information. In this way, the starting method is simplified and simpler. Potential failure risks in various states in the prior art are avoided, thereby effectively improving reliability of a starting process.

Abstract: The present disclosure provides a motor and a motor fixing structure. A first conductive terminal is disposed on the motor, a lead of the motor being electrically connected to an external device through the first conductive terminal, thereby simplifying a manner of connection. When the motor fails, it is only necessary to disconnect the electrical connection between the first conductive terminal and the external device, so that the motor can be rapidly detached without any auxiliary tool, thereby simplifying operations of detaching and mounting a motor and improving the efficiency of replacing a motor.

Abstract: The present disclosure discloses a method for braking a permanent magnet synchronous motor and a related device. The method is applied to an electronic speed controller and includes: receiving a signal for braking the permanent magnet synchronous motor sent by a flight controller; sending a first control signal to the permanent magnet synchronous motor, the first control signal being used to control the permanent magnet synchronous motor to decrease its rotational speed to a preset rotational speed range within a first preset time period; and after the first preset time period ends, sending a second control signal to the permanent magnet synchronous motor, the second control signal being used to control the permanent magnet synchronous motor to stop rotating within a second preset time period. According to the method, consistency of shutdown of multiple motors is ensured, and use experience of a drone is improved.
