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.

well this seems promising i disassembled the lower part of the pump to check the windings.

Image

there is a bundle of cables going from the windings to the connector,

Image

5 cables on this bunch are thicker, the yellow one is even more, there is a thin brown cable that seems to be a temperature sensor it goes in & then out.
The pump indeed seems to have a bipolar motor

this past days i have been thinkering about the pump and how is connected

Image

there are 19 pins on the connector, 5 for the coils 1 grounding the body, 2 that have a 1.5K restistor between them,

Image

Using arduino i managed to isolate the cables that i think are the hall sensors,

AND bingo there they are,

Don’t let the pump run that long in atmosphere. Good job otherwise.

Hi Gustavo,

it looks like you figured it out, but in case it's any help note that the pinout of the motor's connector and its internal circuit are shown on p9 of the user manual for the TCP380 controller (you will find PDF via Google). I don't know what those two components with a Theta symbol by them are. Maybe the resistor shown from pin P to N is a thermistor.

I can also see the service manual for the TCP310. It uses IR3525A PWM controller ICs. I wouldn't fancy trying to replicate a controller from scratch but I wonder that a generic motor controller board could be adapted using the knowledge from the manuals. How did you get on?

Regards
Chris
