Inno servomaglinSeries high-precision circular magnetic grid angular displacementsensorIt is a non-contact open high-precision magnetic grid encoder system used for precise angular displacement feedback. The system uses a special magnetic ring as the scale of the system, even when larger than1mmAccurate measurement can still be achieved under the installation gap. The system adopts a multi reading head design for the diameter, which can effectively eliminate the eccentricity error of the system magnetic ring installation. The special magnetic sensing array design can effectively suppress the measurement error caused by the end face jumping caused by the vibration of the shaft. Meanwhile, the advanced signal microprocessor design enables the system to effectively reduce or eliminate seam errors in special magnetic rings. Especially in environments with large diameters and high pollution, such as high-precision servo turntables, aerospace simulations, and shell shooting aiming systems, where traditional circular gratings or circular magnetic gratings cannot solve the problem, this system can perfectly achieve accurate angular displacement measurement.

This system can output digital incremental square wave signals or analog sine and cosine signals that comply with industry standards for customers with different interface standards to choose from. Unique and concise design makesMaglinThe series of high-precision circular magnetic grid angular displacement measurement systems have more outstanding performance and better stability than traditional angular displacement encoders.

Built in multi reading head processorSet-up LEDThis series of circular magnetic grids can be installed more quickly and conveniently for customers, and can be achieved throughLEDThe color is used to detect and eliminate system faults in a timely manner(Green during normal operation, red when signal error occurs).

MaglinThe series of high-precision circular magnetic grid angular displacement measurement systems can be widely used in various unconventional customized measurement environments such as high-precision CNC digital processing systems, automation equipment, large-diameter servo turntables, theodolites, high-precision angle measuring instruments, torque sensors, seismic wave detectors, gyroscopes, transmission chain dynamic accuracy measuring instruments, screw dynamic accuracy measuring instruments, aerospace simulations, shell shooting aiming systems, military radar arrays, etc.

Installation method:

1、 First, fix the magnetic ring or ruler on the outer or inner circumference of the turntable with adhesive, and try to ensure that the ring plane is parallel to the turntable plane as much as possible;

2、 Keep the turntable rotating at a constant speed;

3、 Turn the reading headAPlace it above the magnetic ring detection surface and observe the multi head processor in real timeSet-up LEDThe color, when reading the headAWhen moving to the critical point where the red and green lights are on, turn the reading headAMove slightly towards the direction close to the magnetic ring detection surface, and then fix it to ensure Set-up LEDThe color is always green；

4、 Next, the reading headBPlace it on the reading headAThe distance between the magnetic ring detection surface and the diameter is equidistant, and a slight clockwise or counterclockwise displacement is made along the magnetic ring detection surface when the multi head processorSet-up LEDWhen the color changes from red to green, it indicates the first reading headAWith the second reading headBThe phase has been calibrated, and now the second reading head will be usedBThe position is basically fixed.

5、 Move the reading head that has already been calibrated for radial phase along the radius direction towards the magnetic ring detection surface, and follow the recommended distance from the magnetic ring detection surface according to the installation dimensions0.8mm）Fixed to ensure optimal measurement accuracy;

6、 Lock the fixing screws of the reading head with thread locking adhesive to prevent loosening caused by vibration, or use epoxy adhesive (permanently fixed at once) to drip onto the fixing parts of the reading head and screw to ensure reliable radial phase and optimal distance from the magnetic ring detection surface. At the same time, adjust the lead output of each reading head and fix it with corresponding plastic clips.
