Will a record weight harm the motor in a direct drive turntable?

I have a Three Metals for Platter Mats, Duraluminium - Gun Metal - Stainless Steel

I have Two non OEM metals as Platters - Gun Metal and Stainless Steel.

Record Weights owned can be used at more than 1Kg.

Certain configurations must be getting up to 14+Kg

The most recent design on the table will end up with another 3Kg+ of Acetal added to a Platter.

As I make it a personal thing, about the quality of the Platter Bearing. In relation to the sacrificial parts selected for the bearing being brought into the modern era. Where materials selected are modern materials and the parts selected are undergoing a machining that is as tight a tolerance as achievable. A Specialist Design for the Lubrication at critical interfaces is also put in place when one is gh adopting this methodology.

A Bearing undergone a overhaul on a owned TT, which is designated to be in regular use is not overlooked, there is always the intention to have periodical inspections.

This approach to having a Bearing Inspection periodically undertaken is quite different to how many many TT's from recent era's of production to Vintage era's of production are being looked after.

Keeping the Objective Focused only on a Denon DP-59L.

The 59L is a 40ish Year Old Model, which it can be assumed, in its usage life has undergone a total rotations of ?????? when the Bearing was at its optimal and has undergone ???????? rotations since the Bearing began to be non-optimal and has been progressing in the journey to being non-optimal through deterioration.

There are conditions that are known to be present as a result of excessive use of a non-optimised Platter Bearing, of which a few are totally not wanted to be occurring within a Bearing Housing.

If a TT user does not know the condition of the Inner of Platter Bearing Housing on the TT being regularly used and the TT owner is considering adding additional items at another Interface under the guise an improvement can be found.

Keeping this to Weight added at the Spindle or Perimeter or a Clamp attached to a Spindle. I'm not seeing how looking into how a Source Medium is to undergo a change for the design for it to be in contact with the Platter through the adoption of using additional ancillaries is going to compensate for unknown off underlying issues at another critical mechanical interface for the TT's function.

The only way for a Stylus in a Groove to not receive an unwanted transfer of energy from a Platter Bearing Housing,  which will be an energy received and sent on as a adulterated signal to be further amplified. Is to have a Bearing Housing that is having the mechanical interface within optimised for their functions, and sending energies that are much much less in their destructive capability.    

VPI are one of a few who are informing on the accuracy of the machining of the Critical Interface Parts that are Sacrificial within the Bearing Housing.

The Classic 3 SE Sig Model owner has the knowledge direct from the Manufacturer that there is a need to put measures in place for an annual Bearing Service, where new lubrication is a basic step to occur. The Good news is there is guidance available in other locations to show how to achieve the VPI direction for the service. The are also today other non VPI suggestions to be found to improve on the Bearing Coefficient of Friction to create a reduced drag when it is rotating.   

The Classic 3 SE Sig Model owner has the knowledge direct from the Manufacturer that to be able to check the condition of the Bearing for signs of Wear, the TT has been supplied with a dimension tolerance for machining of the Sacrificial Parts at the critical interfaces that results with the following as the Supplied TT's Tolerance:

 Platter run-out - +/- .001 inch in 39” circumference as measured on the table 

Such information is a very handy guide to help the TT owner keep track on how the TT is holding out as a True Axis of rotation over time.

Platter run-out - +/- .001 inch is not a bad place to be when talking solely about the Stylus Interface within the LP Groove.

Additionally, the Vertical Axis is likely to be changing in conjunction with the Platter Run Out if the Run Dimension starts to increase.

Changes to the Vertical Axis is the one to show a concern about as this is where the noise is to be produced, and where a proportion of noise produced will be on route to the Stylus when in contact with the Groove.

As earlier stated by a TT owner " The goal, IMO, is to isolate the lp as much as possible from the bearing. "
