Re: [CAD_CAM_EDM_DRO] LPKF 2d drill

Vexta numbering seems to change on a regular basis. I have quite a collection of the 5 phase motors that I have acquired this last year. Some are 10 wire and some are 5 wire. The 5 wire is a no brainer to hookup to the drive because Vexta prints the wire color at the connector location on the drive. The 10 wire I haven't figured out yet. Anyone have an old
Oriental motors catalog? I have PH & PKseries motors and some A series motors. Current production is a AS series. One thing that generally seems to stay the same is that the motor size is in the number. For instance your PH533-NA(B) motor is 5=five phase 3=motor frame size (30mm sq.) 3= motor case length(30mm) The B probably denotes a double shaft? Same with PK
series motors.The size is rounded (85mm would be 90mm) which would be a 9 in the model number.
The A series motor that I have sitting on my lap is numbered A2947-9415. It does not seem to follow their normal numbering system. It is 5 phase and 10 wire. Perhaps made to spec for a certain application or customer. I have gone through the stepper section of the current Oriental catalog and they still use the motor size in the model number.
I was reading in the catalog that 5 phase motors are capable of turning up to 6000rpm.That is screaming for a stepper motor.It just occurred to me that maybe I should take the nema42 motors off of my Bridgeport and put on some nema 34 five phase geared about 4 to 1? What do you think? I have some more coming in the mail rated at 527.8 oz. in.. 1000 steps per turn
at 1/2 step.
The scratched up IC chip sounds like someone other than oriental may have made the driver and purchased the chip from oriental and one or the other removed the id numbers.
