if bypass . the speed is normal = the Box must have issue or the power supply

if bypass not normal .... = your motor...or power supply

if bypass normal...u can still using it too

原來是power supply 出事,輸出得13V. 請問如圖transformer 是否適合project motor 16V 2va ?

有一些你要看清楚, or 已經看清楚及有所準備


No harm for some reminder.. Etc..


Make sure it is AC, not DC, I know some project product take 16V AC, double check

Have u prepare, if u using this 18VAC output tranformer.. Do u have a tactic to bring it down to 16V, u know where to mod to some resistor.. Etc? If yes.. U may need a slightly bigger one.. As it is just not enough for current..

For a few hundred Rmb, or less than 200 u can have one for 16VAc output from China..


Have fun, nice to know why..

Haha

output current of your 16V power is ?

is super likely your motor has no issue..

just wrong voltage ...wrong current...etc..

or i would say...ur motor have issue...

it need more power to run at the speed ...

if it can run smooth... i cannot see why not to give more voltage..etc..to keep it running at 33 1/3

Just wonder there is a cap 250v ac, my input is just 16V ac....

Which bearing ??

A few things

1) double check the manual.. The requipment of power if not using the optional speed box, and that table suppose to be OK without the optional speed box, however it may have other power requirements..

2) check the output voltage of that power supply

3) no harm to clean the platter shaft and the related bearing sleeve.. Etc.. apply. Some new lubricant oil tooi did had some vintage table grt back to speed after some new oil.. Etc.. Just hard to beleive the quite new project may be that reason... But never say never.. Haha


4) if the motor can be oil... Why not, some motor have a little holes for oiling, if not u may drip a few drop of correct oil.. Or at least some not too bad sewing machine oil.. Etc..


Seem to be a common power line filter cap... It does not matter.. If it is 250vac rating or other..
