Thread: DM 45 power feed

Sterob@ Looking and looking but found no specs on the motor, they are able to "lift" a person up on the seat so might be ok, but then again it goes thru the linkage so that is another story.

Morrisman@ I think you can make the wiper go into reverse by swapping the terminals (only on the fastest speed as this connects directly to stator winding), I did try on spit-roast in the past I think. Will try again tomorrow to be sure.

get 6 pole switch then connect as below.
A B
C D
E F

Connect A to F then motor terminal 1
Connect B to E then motor terminal 2
Connect battery -ve to C and +ve to D

Spent a day today and here is what i got.

Nice job Mike

Jackaroo, yours is coming along nicely as well.

Dave

Jackaroo

That is a neat setup ..... I can see myself copying that in the future

Mike

Good stuff!!
It seems to work ok, so that is all that matters.
Are you going to fit a PWM speed control to it?

Sterob

Thanks all.
Sterob@ Yes I am looking to install the mosfet switch and hoping to find a transformer for it. it draws 2.5A without cutting anything, might be a bit more under load I think. I might put a 10amp fuse to it just in case.

I like your switch Morrisman, nice and neat. Its on the to-do lists

Jackaroo

Can you tell me what that motor came out of ?

MOSFET = metal oxide field effect transistor ....???

Mike

Hi Morrisman, the motor is off the driver seat of VX commondore. Very small, 43mm in diameter.

ps: the switch like yours, PWM controller is using mosfet too. just realise you can buy one for $15 off ebay. I used to buy the kits from DickSmith or Jaycar.

HI,
They look Good Guys - Well done. I spotted these on Ebay last Night GEARMOTOR 150 WATT 12 VOLT 200-220 RPM REVERSIBLE NEW | eBay . They have more than enough Speed, but they say a Max Load of 44lbs. I have just sent them a Question asking what they mean by the 44lbs ie in/lbs , ft/lbs or something else. I know the Power Feed that Shars Sell are 165rpm and 135 in/lbs I think the Rapid Speed is 220rpm. Do You Guys think that they would Work Ok ?. I am Concerned about the simple Pin arrangement that needs to be used to Key the Drive Shaft to the Motor.

very interesting Stewart

I wonder if the gears inside are plastic or metal ?

Looks promising Stewart. My only concern is the output shaft. Not sure how tricky it would be to interface with the Mill.
When I did this, I went the 'direct drive' route and used a dog clutch. It is alot quieter and using this method with this motor might be more problematic....I don't know.

I've done a bit more on the power feed.

Bought this speed control on ebay for about $10, the box is $5 and the switch is another $5 or so.

Hi jackaroo,
Almost there, a little neaten up and maybe a cover over the gears to stop swarf and you're done. Or are you planning to add travel stops?
