EIZZ brand LP player system products:

EIZZ recommends one of the options is interchange and permanent magnet to work for the motor. ​Made in Germany called SCHNEIDER, the characters are:

1.Suitable for continuous loading, it can supply the disc secular stability for transferring.

2.High output transferring characters and make the maximal quantization to make sure the greatest rate of work, rate of density.

3.Temperature scope:  No rotating distance changing between -20C-60C,;

4.Overload characteristic: 4 times peak value, which can inhibit to rotate the distance.

5.Insulate tube of no bearing weight side, no current completely, which enhance the working life.

6.High quality magnet material, No demagnetizing within several weeks for the whole machine.

7.Compound winding characteristic works perfectly with driving system, so it can help sound wave spread perfectly.

8.With the most comprehensive industrial department certification

To sum up,EIZZ chooses AC permanent magnet synchronous motor in motor selection.

It has a deep understanding of the load characteristics of the turntable in EIZZ makes the excitation and torque control completely independent, and follows the most stringent industrial standards as the selection basis, so as to realize the optimal selection from performance life /reliability and provide the most powerful heart parts for therotable.

There are coded keys/speed instruction of potentio meter/, the electrode will softly start by speed slope of integral curve.  The design gist is according to the slope time: In which there is no slip for the belt.

The up one level speed will transfer to the input end of speed adjuster, the speed adjuster has two ports,one is the feedback of electrical machinery (The functions of sampling voltage and frequency is the setting valve of rotating speed), in this period of speed adjusting, PID adjusting is used . Among:

1.Adjuster P controls the response speed, to fit the inertia character of turntable, also setting related coefficient and rotate plate GD2.

2.Adjuster I acts as stabilization precision of system, it's the most important adjuster for disc system.

3.Adjuster D function:

Due totheinertiasystem of rotate plate,for some reasons, (such as inclined disc, concentric error or shaking),

4.Adjuster D will reverse to control in advance when the rotate plate is overshoot. We call it controller in advance.

So under the function of speed adjuster, meanwhile making sure the rotate plate is stable, the speed adjuster has initiative and pre-control characters when there was disturbance of outside.

The time of adjuster’s operating cycle is controlled within 100ms. It fits the demand of disc.

In the system of speed adjuster, sampling voltage will limit the amplitude, so there is over voltage protection for electrical machinery. The other port of speed adjuster is compensation of rotating speed, it is assembled on the thread 1024 incremental encoder of the rotate plate. It can check the speed of rotate plate.

If the speed is changing because of belt creep or other reasons,it will compensate this port, means speed will be super position with the previous speed.
