Hi,
I bought one old Oracle Delphi MKII with broken Papst Motor. I am looking for a new motor for Delphi.
After readings some posts about turntable motors i decided to go Maxon way.
I already bought on ebay one LSC30/2 controller.
Now i am thinking, which (new) motor should i buy - 110191 or maybe 226774 RE MAX ?
I am tending to take 226774 RE MAX like Linn Radikal
The platter on Delphi II is not so heavy - 2.7kg.
LS30/2 need one 2A power supply. 10 to 30V DC regulated (LM317 ?) ?
The input voltage of LS30/2 is changing the rpm ?
The connections possibilities on LSC30/2 are confusing me a little ...
So - with dip switches i can set the IxR mode, which is adviced for this kind of application.
Then they are five potentiometers P1 to P5
Their function is little unclear to me ...
P1 maximum speed at maximum set value ? what does it mean ?
P2 IxR compensation - how should i set this one ? do i need a speed sensor to use it ?
P3 rpm offset, most probaly 0 ?
P4 current limit - for 110191 is ~0.7A ?
P5 with this one i can set the motor rpm ?
For the exact rpm controll i should use two (33 and 45) potentiometers. Which values ? Any advice ?
Later with one switch i can change speed beetwen 33 and 45 rpm.
So the whole ps will be like this:
Power supply ~10-30VDC - switch 33/45 - potentiometer for exact rpm setting (1 for 33, one for 45) - LSC30/2 - motor.
Is this right ?
I am thankfull for any advice
