Application of Stepper servo Motor System in Tethered UAV

Mooring unmanned aerial vehicle (uav) is combined drones and mooring rope implementation of uav system, mooring unmanned aerial vehicle (uav) by photoelectric comprehensive power transmission cable, the aircraft can not restricted by power and long time stay in the air, its structure size, production materials can be designed according to the application requirements, and maneuverability is strong, according to different application scenarios, the mooring uav system is divided into stationary, vehicle-mounted mobile and carrier on the ground, three works well meet the needs of the various working environment.

Usage Details:

Man-machine conversation layer: none

Configuration: switching power supply 48V, 10A

Control layer: PLC

Driver layer: The third generation step servo drive (economy) 60EDC-H-III

Executive layer: Zhichuang Motor 60EMC-HC-II

Installation location and functions:

The stepper servo motor system of our company is mainly used in the retracting system of UAV. The structure is motor acceleration and reduction machine to drive the retracting coil.

Usage Details:

Driver pulse type is set to monopulse plus direction, subdivided to 1000

The running state is as follows:

The running and starting speed of the motor is determined by the state of the line.

Selection practice:

Due to the influence of the external environment and the process requirements, the speed and locking force of the motor should be guaranteed during the winding process.

At the beginning of the project, open-loop stepping is adopted, which can meet the requirement of locking force when stopping, but the speed cannot meet the requirement when automatically winding.

After that, I also considered using servo drive. However, due to the influence of external wind force, the UAV pulled the wire disk, which finally caused the servo drive to step out of step and gave an alarm, which could not meet the requirements.

The final customer chooses the third-generation stepper servo motor system provided by our company, which can not only meet the requirements in terms of speed and locking force, but also avoid alarm in case the motor is out of step.

Customized for customers to meet customer requirements.

However, the step servo system of Zhichuang is simple in parameter setting, and can maintain the best effect in the whole range without tedious adjustment. After reaching the ideal target position, the motor has no position fluctuation.
