Spindle motor or controller?

Hello Mike,

The first part of the number is the motor distributors designation, that last part corresponds to the numbers given in the PJM listing. Knowing the physical dimensions and the motor power, you should be able to find the correct one.

I would Email PJM and give them the numbers that are on the ratings plate asking if that motor is one of theirs and if they will supply you with one. Also ask for a price along with carriage charges. You may be surprised !
 
Update Monday, Aug 20th

I have a question that maybe someone can shed some light on.

I still haven't pinned down the problem with the spindle motor on my Syil X4+ CNC mill. In other words I still don't know if it is the motor, the control board or the wiring/connections. But it really doesn't seem to matter because there don't seem to be any replacement components anyway. I am going to have to replace both the motor and controller with a 220V set (the mill is now 110V).

First off, I can easily supply the 2 different voltages. But can you foresee any problems running the spindle with 220V and the X, Y, Z axis and other components at 110V? The suppliers I've been talking too don't seem to be concerned.

Second, I've found have a system usiing a motor with the exact physical dimensions as the one I have. But theirs is less powerful and slower turning;

AC Servo Drive - H01 Frame
0.75~1.0kW servo motor pair
0.75kW AC servo motor Rated 3000rpm, Rated torque: 2.9Nm, Peak torque: 7.2Nm

while my old motor is labeled:
300V DC
4.3A
1100W
3.14Nm
3500r/min

Is that something I need to be concerned about (or is it likely my old motor label is just a bit over rated)? My actual top speed was 3470 by hand-held tach and of course I don't know about the torque. I really was hoping for a bit more speed, not less.

(Note: Syil Corp. in China has offered to put together a similar package - but they haven't responded for my request for pricing and specs in almost a week. They might have a more powerful / faster set or a better price but I don't know??)

Any thoughts you have would be greatly appreciated as I am totally uncertain what I should do.

Thanks,
 
I answered this in your PM to me, but I'll post it here also for the benefit of others.

There shouldn't be any problem running the spindle at 220 and the rest at 110. I would just bring in 220 with the neutral and split off the 110.

I can't find that motor in the DMM specs. That would be a 92mm frame, and all I see is a 86 and a 130, no 92. Is this something you inquired about directly to them? The 0.75KW motors seem to have a 3000 RPM base speed with a 5000 RPM max speed.
 
Jim, PM replied to - thanks

In short; yes, I've been talking to Michael Tien at DMM. He is very helpful.

I think I will order the goodies from DMM tomorrow. He said a week or so to delivery. I'll keep this forum (and Jim) up to date!
 
I never did email then because it was looking likely that it isn't the motor. I just went with DMM (who Syil said would be the best route for help).

Speaking of which, I was under the imperssion that it would take several days before they could ship. I placed the order this morning and received a shipping notice to look for it Thursday!
 
Dec 2018 update:

Have been working with DMM since the end of August. Help (as promised) with installing their motor has been VERY slow between responses. Now it seems they have given up and my mill is still not working. Not able to combine the DMM drive with the existing controller.

Since it seems that controlling the new DMM motor with my existing control system will not work, I am wondering if I can replace the control system (breakout board, whatever) with a new system. I need someone or some company to help design a control system that will work with the new DMM spindle motor (or return that one and purchase something else) and any compatible existing hardware (like my power supplies, axis motors & drives, etc).

I do not want to redesign my CNC as a hobby project. I do not know or understand CNC control systems nor do I want to - I just want to get the mill working as easily as possible. I haven't found any motor or electrical companies locally who can help. I have sent all sorts of component specs, schematics and pictures to 2 on-line companies who say they can help - but they have not.

Does anyone have the knowledge to help me or know where I can go for help. I am not asking for free help. I am willing to pay but I cannot afford to spend any more without results. Between the new DMM motor/drive, wiring the shop for 220V, contactor, filters, etc. I am about $1,000 and many hours into this and no further ahead than the day it broke in August.

I appreciate any realistic ideas anyone might have

Maybe post the same here. We're pretty good at figuring this stuff out, and have installed a number of DMM servos. And best of all it costs nothing. :)
