My son an I are attempting to cannibalize a printer a HP LaserJet 1300. It used to work and print, but it was low on toner and the company we got it from replaced it instead of buying new toner.
So, we have some parts and are trying to build a centrifuge (the low tech version) using the motor inside the printer. It is a Nidec RK2-0063 45M0600024 24VDC 1.4A. You can see what it looks like here: http://www.kpsurplus.com/hp-printer-nidec-rk2-0063-main-motor-45m0600024-24v1-4a.html
Anyway, we have been drawing a blank on finding a datasheet for this motor/control assembly. The 5 pin connector has a pinout of Vcc FG /DEC /ACC GND but we don't know what FG means, and don't know what to feed it on /ACC and /DEC
Vcc -> Gnd is ~24 VDC which is to be expected since it is a 24 volt motor, but what are the other pins for/what voltages should we use to control the motor.
What kind of motor would you call this?
Best Answer
It's probably a "Brushless DC Motor" (BLDCM or BLDC motor).
If so it will have a controller on board.
The following is experienced based guesswork
/ACC = accelerate motor when grounded (/ indicating low)
/ DEC = decelerate motor when grounded.
Vcc is probably 24V but just may be eg 5V.
Gnd - something has to be easy ;-) = ground.
/ FG may be "frame ground". But maybe not.
I'd be tempted to find old printers in a dumpster and tear them apart rather than buy one like this BUT it does seem to be a very capable motor from the rating plate. Have you asked the supplier of they have a basic data sheet - you'd hope they would have when selling something like this.
TRY
Connect ground to ground. So far so good.
Connect 12V or so to Vcc via a 100 R ( = 100 ohm) resistor.
Ground /ACC via a 1k or so resistor.
IF the motor responds go from there.
If not,try 24 V, but I'd be mildly nervous.
Once/if it shows signs of rotating (even a kick) you can try removing the 100 R resistor.
FG may need to be grounded.
If there is an onboard IC it may give some clues.
Report.
