Supporting control system

Electric displacement mechanism
Supporting control system
Electric displacement mechanism and motion controller are the two main auxiliary devices in the measurement and control of flow field,which can drive the sensed parts such as pneumatic probe mounted on it to move accurately in 3D coordinate system and provide guarantee for efficient and accurate measurement.The WTN-NL series of electric displacement mechanism generally consists of a translation platform and arotary platform,which can meet the requirements of 3Dspace and multi-pointfine measurement;the motion controller WTN-PMACBO4 can accurately control the electric displacement mechanism through the integrated WindLabX software.

Advantages of electric displacement mechanism

Heavy load translating and rotary platforms can be customed.
Worm gears are precisely matched for comfortable movement and lowbacklash.
The transmission adopts worm gear structure,the platform can be rotatedforward and backward freely.
Stepping motor as standard,can be replaced by servo motor,suitable fordifferent applications
Stepping motor and worm gear are connected by flexible coupling,withsynchronous transmission and low noise.
The cleverly designed clearance elimination structure can adjust the clearance caused by long-term use.
The rotating shaft system is made of bearing steel,which has high coordination,great load and long service life.
The diameter of the central hole is limited by tolerance,and the central hole coincides with the centre of rotation,which is convenient for positioning.
The outer ring of the platform is ascaled ring,the surrounding laser engraved scale can ratote relative to the platform,which is convenient for reading and initial positioning.

Advantages of motion controller

Asymmetric linear acceleration/deceleration drive,S-curve acceleration/deceleration drive.
The number of output pulses or drive speed can be changed during motion.
Logical position,actual position,drive speed,acceleration speed,acceleration/deceleration status(accelerating,constant speed,decelerating)can be read in real time during motion.
There are two 32-bit comparison registers for every shaft to compare the position size of the logical or actual position counters,which can be used for software limits.
Can receive various signals from the servo motor drive,such as hardware limit signals,position signals,alarm signals,etc,32-bit increment/decrement counter used for additional encoder.
The corresponding software parameters can be modified according to the hardware parameters of the electric displacement mechanism,which can beflexibly adapted to the control of variouselectric displacement mechanisms.
