Thread: table drive motor identification
03/08/2012 16:21:10

I have upped more photos of the electrical board. if i were to change the transformer in the top left hand side of the board to a 240v -24v out would that work ? the components on the two boards seem to be 12 and 24 volt pieces.

Firstly , thanks to all for replying to this thread , i didn't know i could power this motor from single phase power. This is a relief as it saves me altering the machine and also the cost of a vfd. Heading to the shed now to investigate this.

Thanks for your reply andrew, I may replace this motor with a ac type and drive it with a vfd so. Is there any other method of operating this motor from a single phase supply ? There is quiet a lot of electronics in the board in the base to operate this motor, but i don't have a three phase supply and don't intend to get it.

The x-axis power feed on my tom senior universal mill is powered by an electric motor rather than mechanical means. I ideally want to power this motor from the usual inverter/vfd, can anyone help me identify what type of motor i have ? it can be seen in the pictures in my album. The main motor has been disconnected from the electrical board in the base and connected temporarily to the vfd i use for my lathe so the machine is operable, but i would like to get the table feed sorted.

p.s its the one with the "kemo" nameplate.

Thread: tom senior mill help
26/07/2012 17:15:56

I found the problem , it was a loose grub screw in one of the gears on the main spindle which engages with the back gear. A few turns of a wrench and the sound completely disappeared, whew !

New member here, i am a fitter/turner by trade , with an interest in all things mechanical. In the shed i have a colchester master 2500 lathe , and just last week i bought a tom senior universal milling machine. This is the final version of the m1 major and mine dates from 1981. This mill came out of a community college and had one owner before me. The machine is in excellent condition , there is no wear and it is still tight.

I connected the machine up to my vfd just to see it running and was alarmed to hear a knocking noise from the shaft that drives the cutter. Would anyone have any experience with these models of machines ? or failing that a manual or an exploded view. I don't want to dismantle anything needlessly.
