Motor module, pan head, unmanned aerial vehicle and control method of pan head

Abstract

The invention provides a motor module, which comprises a rotor, a stator, a brake pad, a driving device and a control board. The rotor comprises a rotor side wall and an extension wall. An accommodation space is formed between the extension wall and the stator. The brake pad, the driving device and the control plate are accommodated in the accommodation space. One end of the brake pad is hinged onone side of the stator close to the rotor, and the other end of the brake pad is fixed on the driving device, and the driving device drives the brake pad to abut or separate from the extension wall;The control board is provided with a capacitor and an elastic switch, the capacitor is electrically connected with the driving device and supplies power to the driving device, and the elastic switch is used for connecting / disconnecting the control board and the driving device to control the capacitor to supply / cut off power to the driving device. The invention also provides a pan head, an unmannedaerial vehicle adopting the motor module and a control method of the pan head. Compared with the related technology, the electric motor module, the pan-head and the unmanned aerial vehicle of the invention are small in volume, good in reliability and safety.

Description

【Technical field】 [0001] The invention relates to the technical field of motors, in particular to a motor module used in aviation, a cloud platform, an unmanned aerial vehicle and a control method for the platform. 【Background technique】 [0002] Unmanned Aerial Vehicle (unmanned aerial vehicle, UAV for short) has the characteristics of small size, light weight, low cost, flexible operation and high safety, and can be widely used in military, monitoring, search and rescue, resource exploration, agricultural irrigation and other fields. Taking mechanical work as an example, it is another important function of UAV besides aerial photography. Install the robotic arm on the gimbal, and control the two-dimensional or three-dimensional rotation of the gimbal through the motor module to realize the position adjustment of the robotic arm. Perform related work. [0003] The motor module in the related art includes a motor and a reducer combined with the motor. The rotational speed o...

Problems solved by technology

[0004] However, the motor module in the related art can only realize the steering control of the gimbal by outputting power from the rotor when the power is turned on, so as to realize the direction control of the mechanical arm. When the power is turned off, the motor module has no power output, and the rotor handles freely. In the state of motion, the mechanical arm can swing freely under the action of external force. During transportation, etc., the mechanical arm is easy to cause damage or injury due to collision due to free swing, poor reliability and serious safety hazards.
