TMH-260 Turbo

Every fusor and fusion system seems to need a vacuum. This area is for detailed discussion of vacuum systems, materials, gauging, etc. related to fusor or fusion research.

TMH-260 Turbo

Post by Gustavo Cervantes » Thu Apr 05, 2018 1:46 am

Hi everybody im new to the forum,
as you can imagine im currently trying to build a vacuum chamber to gain konolowege and in the far future turn it into a fusor.
Last weekend i managed to get hold of a pfeiffer TMH-260, very dirty and with a broken ceramic bearing but still i think is reusable

You can see the only damage in the rotor is a small bumb in one of the blades.

Im coming to you asking for imformation about the driver, conection voltajes etc etc,

BTW, English is my second languaje so dont hesitate to correct me.

Bearings likely available from Alpine Bearing. Expect to pay hundreds of dollars.

You'll need to balance the rotor. There are some cheapish tricks you can use for this.

but you failed to do that. Please change your username to comply.

Changing your Username

The forum rules require you to use your full name as your username. Many people miss that and create an account with some tag name.
This forum does allow you to change your username. I just tried it and it seems to work for me.

Here's how:
Login to the board
click your current username in the upper-right of the main page and select User Control Panel from the pull-down
In the tabs at the top, select Profile
At the left column, select Edit account settings
Edit the Username: field to be your full name
Type your password in the Current password: field (near bottom of page)
Click Submit button at bottom
Note: After you change Username, the new name becomes what you use to login to the Forum. Your password should remain the same.
I also suggest adding a Location to your profile. It often helps to know generally where a member is in the world while responding to them. I have used my City and State, but if you are worried it could be more general -- just State, something like Central USA, just your Country is better than nothing.

Adding a Location
(Skip the first 3 steps if you are already in the Profile section from doing the Username update.)
Login to the board
click User Control Panel near the top of the main page
In the tabs at the top, select Profile
At the left column, select Edit profile
Edit the Location: field
Click Submit button at bottom
This Location information will appear in the right column, under your name, when you post.

thanks to Rex for this

Hi Gustavo,

Finding the correct wiring can be a real pain - also it might need 3-phase power to run. I tried this with my TMH pump and ended up just resorting to buying the controller. You might end up having to do the same.

I've attached the pump's manual, that might be of help to you.

Also, unless you've just disassembled the pump its missing atleast the stators and the rotor housing, maybe more.

i have read a the manual a few times before posting here, but i cant fin the pinout anywhere, the point of that is to make the controller (i have a little experience making triphasic motor controllers for BLDC motors), but without knolowedge about the array of coils i dont thing i can.

A lot of pfeiffers are two phase. You will have pins for that, an eeprom, and a temp sensor. I am not sure if they have halls.

At least 6 pins have continuity between them .5 ohms or so, this confuses me a little, because not all 6 have the same resistance, probing with the meter some have .2 ohms.
I dont have an lc meter to acurate measure the inductance of the coils, may be the best idea is to disassemble the pump, pull out the stator coils and see how its arranged.
