Looking for a 3 phase stepper dirver
« on: May 16, 2007, 02:45:33 AM »
Guys , I've got this nice set of stepping motors , wich i'd like to use on my mill .
The mill is an 1972 alcera 600 , wich will be fully rebuild prior to cnc converting .

Only they are three phase bipolar instead of the usual two phase bipolar .
I just can't seem to find an integrated driver for them . I'm not looking for a driver board .
I just need to find a chip that can do the logic , and possably micro stepping .
A bit like an L297 for a bipolar 2 phase motor .

On the back of the motor is written :
Sanyo electric stepping motor
Type 103-606-i
3phases /10 Ohms / 30VDC
PN 18460782


Any help appreciated .

Looking on Google for data on the 3 phase Sanyo stepper 103-606-i I ran into this forum and read you request.
I am using 3 phase steppers although not from Sanyo but I run them with the HA13532 controller from Hitachi.
As driver I use the SLA6023 from Sanken.
I build this driver board with the components I took from the original driver board in the Konica copier the motors
came from. I think the chips are hard to get in normal live.
Because we have more motors then controller chips we are trying to build a controller with a GAL or a micro
processor. In the coming weeks we will do the first test with a GAL design.
So if you are interested I will keep you informed in this thread.
