Sanyo P5 1kw brushless motor spin video

[KTP]

Hi guys,

As I promised, I made a quick video of one of my Sanyo-Denki P5 1kw brushless motors running on a BDC25L (same as an AMC drive) and my Pixie step/dir to analog +/-10V PID controller. Some of you asked how smooth the P5 is at low speed...as you can see in the vid, VERY smooth indeed. I am quite pleased with the quick response of this motor too.

Here is the link to the video:

I used Mach2 and programmed several slow and fast moves to try and show the smoothness and response time. There is sound also, but the motor is pretty quiet, so turn up the volume.

Is this running step/direction or +/- 10 volt?

Also just how much are the boards?

[KTP]

It is under a full PID control taking step/dir inputs from Mach2 and sending out analog voltage to the BDC25L which is operating in current(torque) mode.

The boards are $59, fully assembled and tested.

I use Mach3 so that works for me
The 503 copley runs in torque mode; so i guess I'm getting more interested

I just finished the data sheet for the Pixie P100 servo controller and posted it to my website in both pdf and Word doc format. Here is the link:

Johan: Yes, the Pixie can be used with other drives than the BDC25L...I have run it on several AMC and Copley drives as well.

hi i have 6 of the 1000w p5, and have been trying to get amp for them, i cant find the amps u bought on ebay but you said it was just a amc one?? which one cuz ther are a lot of amc drive on ebay cheep!! also due you know anything about this amp its on ebay cheap Teknic SST-1500 servo amplifier i will be needing 3 or 4 of your p100 converter also have you tryed using it to run a spinle vfd??

Hi,

Yes, the AMC amp that is identical is the BD25A20AC.

Not familiar with the Teknic amp, but if it takes a +/-5V to +/-10V analog control voltage, it will probably work with the Pixie.

I have a 5HP DC spindle motor on my mill and a fairly cheap 5HP four quadrant drive, but the spindle motor does not have an encoder (yet) and the drive uses a non-isolated pot to control the speed. I may try it with a Pixie one day, but I would have to do some work, obviously.

WOW this could very well be the answer to my prayers!!!!

And to think of all those awsome torque mode input drives I passed up on Ebay because I will be using S&D software.....

While there are some awsome S&D brushless drives out there for hobby work, I'd still rather use a drive from the same manufacturer that made my motor, and now I can!!!

Although, this does give me one more option to consider, thus, perhaps I'm just more confused now...

[KTP]

The Pixie is about as easy to use as it gets...no confusion!

Though if you want to keep passing up the analog input drives on ebay I will be happy to keep getting bargains to use with Pixies in my projects.

[PeteZ28]

Of course, I'm looking now, and the generally abundant analog drives seem to be a littel scarce this week.... better get them soon before people catch on and the prices go up!!!

Hi, Real new here. Don't know if this is the place to jump in. I really need some help! Starting my first CNC router. I acquired Torque Systems PM Servo Motors BNR3312APG00HS0008. As far as I can tell they are brushless. Will this board drive them and if so where can I buy them? I don't want to become an electronic technician I just want to CNC. Thanks

Hi Clay,

More info on the Pixie can be found at www.skyko.com.

You need a suitable motor amplifier to go between your motor and the Pixie P100. The Pixie is a step/dir to analog interface, although it does do full PID control with encoder feedback of the motor's position. If your motors are brushless motors, you would look for a brushless amplifier of suitable voltage and current rating...perhaps like a AMC B15A8 or a Copley 503 (513 for higher voltage).

If the motors you mentioned are just plain brush motors (not brushless!) and require no more than about 80V DC to run at the speed you want, I would recommend a Gecko G320 drive www.geckodrive.com. You will not have quite the ease of tuning of the Pixie/motor amp combo, nor will you have the ability to adjust the position-error-before-fault setting (fixed at 128 encoder counts in the Gecko), but it sure is a nice inexpensive product when the application fits.
