MAXIMAT V10 milling attachment

[JIMNORTH]

Hi. This is my first ever posting and it took me awhile to get this far -not to great with technology. I recently acquired a a V10 milling attachment sans everything. The 110 volt motor has three wires, a black, blue and green/yellow. I was wondering if someone out there could tell me exactly what should be connected to what. I think a running capacitor is required. As I recall if I connect 110 volts across the black and blue it runs, but with very low torque. Looks like a great little unit to mount to the back of a lathe someday if I can make a mounting bracket.

Your are probley right . Black hot ,blue common , green yellow is Ground.

Welcome to the gang.

I have a Maximat Mentor 10 which has what should be essentially the same milling head. And I have the wiring diagrams.

It's in the shop, and I'm in the house, and I'm done for the day, so tomorrow I'll get the info for you.

You are correct in that it has a capacitor separate from the motor.

That's a european device, and green/yellow is ground for sure.

How certain are you that it is for 110? If for 230 (quite normal for european) it would have crummy torque on 110. But the normal 230 cord is brown and blue.

Jim, How much of the milling attachment do you have? When you say you have to make a mounting bracket is this to fit the column or something to mount on the lathe. The reason I ask is that I have a spare milling attachment that got flooded in Katrina sitting on the floor in my shop. Not sure what I am going to do with it. A friend of mine gave it to me.

I have a V10 also and have all of the manuals. If you don't get the answer on the motor I can look in the manual and maybe copy some information for you.

I am looking for a motor for the V10 lathe, 110 or 220 volt single phase but would consider 3 phase. If anyone has one that they want to part with PM me.

This looks like the confession thread: "Yes I have an Emco".

I have an Emco Maximat V10P + mill. I looked in the manual, they don't give a value for the condensor. Having 230 volt the value of mine would'nt necessary be the same.

The motor is a standard European size. I replaced both motors with 3-phase motors and 2 VFD's. A conversion, which doesn't cost that much and that I can recommend. You lose the 2-phase rumble.

I also tucked a timing belt drive (mill: motor to gearbox) in the head. The standard phenolic gear is a weak link and cost a fortune.

Hmm..this sounds interesting.

As I expect others would be interested in a similar conversion, could you get into the details?

WHAT motors and VFDs?

Also the timing belt drive conversion on the milling head is well worth a few pictures along with the lathe conversion.

Thanks

Thanks for the replies. To answer some of the questions that have come up I checked out the motor name plate and checked the leads with an ohmmeter. The name plate is only partly ledgible but the top section has 115V , 0.18KW, 1700 rpm. The green/yellow lead is not ground (high megs to motor base)! Blue to yellow/green is 4.5 ohms, blue to black is 14.5 ohms, and green/yellow to black is 19 ohms. I think that means the blue is common. Also, The unit is actually complete including the 70 mm column, just no lathe or bracket to join the two. JIM

From UL 60065 section 15.2:

"Wires identified by the color green or combination green/yellow shall be used only for protective earthing conductors."

That is an international standard, IEC60065 , EN60065 in the EC. In IEC 60065, the comnination is always ground.

It appears that someone didn't pay attention, or else that unit is so old that the color standard wasn't established, or it is seriously defective.

As it is, it is unsafely wired, and suitable to fry users who atttempt to follow any sort of standard in its use.

That wire must be actually for the capacitor and the unit must be a capacitor-run motor.

I'd cut it short and put on a wire that would not be identified by every electrical worker on several continents as ground.........

OK, I've got my manual in front of me now, and it looks like I can clarify everything to the point of absolute opacity.

One diagram is for the V10P. For the vertical head motor, single phase, 60 cycle, it shows: Black, Blue, and Brown. The capacitor is between the Black and the Brown. An adjoining drawing shows a Yellow-Green ground wire in the cable, also.

In the diagram for the Mentor 10, the vertical attachment motor has 7 wires, Red, Black, Yellow, Grey, Blue, and Brown, plus one labeled "st." Funny, I don't remember that many wires.

Each of the two motors has it's own separate capacitor, and there are no centrifigal switches...the caps stay in the circuit all the time.

These machines have evolved and changed over time, and the wiring for mine (1975) may not necessarily apply to an older or newer unit.
