Application of integrated servo motor in LiDAR equipment
As an important sensing technology, LiDAR is widely used in weather detection, tracking, robot navigation, wind resources and other fields. In the LiDAR equipment, the application of integrated servo motor is playing an important role.
This paper will introduce the advantages of integrated servo motor in the application of LiDAR equipment, and show its role in promoting the development of Lidar technology.
01. Introduction
With the wide application of Lidar technology, the miniaturization and high performance of equipment have become the development direction. This trend has led to a new generation of liDAR systems based on integrated servo motors.
Compared to traditional split motor and drive designs, the integrated servo motor integrates a permanent magnet synchronous servo motor, controller, driver and encoder, making it smaller and more efficient.
These characteristics make it ideal for use in liDAR devices with strict requirements for volume and weight.
In the new LiDAR system, the integrated servo motor is mainly used in the precision motion control of the sensor architecture to achieve higher precision laser scanning and stabilization.
LiDAR with integrated servo motor has the characteristics of light size, dynamic response and agile, and can be mounted on various mobile platforms to meet the demand for miniaturization and high performance.
For example, in ranging and scanning liDAR, the integrated servo motor can drive the Angle and position control of the laser transmitter, so as to achieve fast and accurate scanning of the target area.
02. Application Scheme
In the LiDAR equipment, by setting the contour position mode at the control end to control the integrated servo motor to do position movement, three-dimensional wind field detection can be realized, and the detection area can be covered in a large range.
Motor model:PMM6020B
Control mode: Contour position mode
Through the upgrade of the servo scanning control system, multiple scanning modes such as DBS, VAD, PPI, RHI and CAPPI fixed point can be realized to realize the fine detection of three-dimensional wind field from ground to high altitude, and the effective data of wind field such as vertical wind speed, horizontal wind speed and full current intensity can be measured stably and accurately in real time.
【 Advantages of Integrated servo motor 】
High integration improves device portability: The integrated servo motor integrates functional modules such as brushless motor, driver, encoder and controller, greatly reducing the volume and weight of the device. At the same time, simplify the system wiring and reduce potential points of failure.
Flexibility to meet diverse needs: The integrated servo motor supports CAN/CANopen/Modbus communication, which can be flexibly controlled and adjusted according to needs to adapt to different work needs.
High-precision positioning to improve measurement accuracy: The integrated servo motor has a high positioning accuracy, which can achieve high-precision positioning of mobile devices.
Multiple control modes: Support PP, VM, PV, PT, HM, IP, CSP, CSV, CST Standard mode; Supports NiMotion position mode, NiMotion speed mode, and NiMotion torque mode.
High-speed response improves equipment efficiency: The integrated servo motor has a fast response speed.
Perfect alarm function: integrated servo motor power-on self-test diagnosis, can detect hardware faults in time to avoid affecting system operation equipped with a variety of safety protection functions, through the LED Flashing alarm, visual display of the current state of the motor, while with overvoltage/undervoltage, overheating, overcurrent, gridlock alarm and other protection functions.
