Application of integrated servo motor in tethered drone
The integrated servo motor is a servo system that combines a motor, a driver, and an encoder. It has the advantages of high-precision control, fast response, and efficient operation. A tethered drone is a drone that is connected to ground facilities by ropes or chains, and can achieve long-term stable hovering and aerial operations.
01.Equipment Introduction
In a tethered drone, the power cord needs to extend from the ground facility to the position where the drone is hovering. In order to ensure the stable transmission of the power cord, the integrated servo motor can be used as the core component of the power cord pulling device.
By controlling the rotation direction and speed of the motor, the power line can be retracted, extended and adjusted, which can not only improve the efficiency of power transmission, but also ensure the stability of power transmission.
Automatic retractable device:In some application scenarios, the operation time of a tethered drone is long, and the power cord needs to be frequently retracted and released.
In order to improve the working efficiency, the integrated servo motor can be used with the automatic retracting device. When the drone needs to be charged or the power cord needs to be retracted for other reasons, the integrated servo motor can control the power cord to be automatically retracted.
When the drone needs to operate again, the integrated servo motor can control the power cord to be automatically released. This can not only improve the operation efficiency, but also reduce the errors of manual operation.
Monitoring system:In order to ensure the stability and safety of power transmission, the integrated servo motor can be used in conjunction with a power status monitoring device.
By monitoring the current, voltage and other parameters of the power line, the transmission status of the power line can be understood in real time and abnormal conditions can be discovered in time. This can not only improve the safety of the operation, but also extend the service life of the power line.
02.Example
Integrated stepper servo motor for tethered drone equipment
In actual applications, a smart technology company uses an integrated servo motor drive system to achieve efficient and stable power transmission, thereby improving the operating efficiency and safety of tethered drones.
The power cable is retracted at a speed of 240RPM with 15% torque in the motor profile torque mode, and the other end of the power cable pulls the drone. When the drone is flying and descending at high speed, the motor continues to retract the cable to ensure that the cable is always straight.
Motor Model:PMM6020B-485-LB-0HE(Short)
Control mode: Contour torque mode
03.Advantages of integrated servo motor
High integration improves the portability of equipment: The integrated servo motor integrates functional modules such as servo motor, servo driver, encoder and controller, which greatly reduces the size and weight of the equipment. At the same time, it simplifies system wiring and reduces potential failure points.
Flexibility to meet diverse needs: The integrated servo motor supports CANopen/Modbus communication and can be flexibly controlled and adjusted as needed to adapt to different work requirements.
High-precision positioning improves measurement accuracy: The integrated servo motor has high positioning accuracy and can achieve high-precision positioning of mobile equipment.
Multiple control modes: support PP, VM, PV, PT, HM, IP, CSP, CSV, CST standard modes; support NiMotion position mode, NiMotion speed mode, NiMotion torque mode.
High-speed response improves equipment efficiency: The integrated servo motor has a fast response speed and can quickly adjust the angle and position of the detection equipment. This means that the detection unit can obtain sample information more quickly, improving the working efficiency and responsiveness of the equipment.
Complete alarm function: The integrated servo motor can detect hardware failures in time to avoid affecting system operation. It is equipped with multiple safety protection functions. The LED flashing alarm can intuitively display the current status of the motor. It also has protection functions such as overvoltage/undervoltage, overheating, overcurrent, and stall alarm.
