Topic: Three phase motor with driver IC (Read 1 time) previous topic - next topic

Hello,

trying to run this three phase motor that was taken out of what i think is a laser printer assembly.  I see that it has a driver HA13535 and 4 wires leading in.  I did a quick check with my multimeter.  the first two wires, the red and black, have a 16 ohm resistance, and the rest are seemingly isolated. 

Can anybody help me put together an arduino program to run this thing?

My guess is that the red and black wires are +ve supply and GND, and the other two are the CK1 and DIR/CK2 inputs to the chip. If so, then each time you pulse CK1 with DIR/CK2 low, the motor will move 1 step. To move it the other way, you will need to (depending on how the chip has been wired) either pulse CK1 with DIR/CK2 high, or leave CK1 low and pulse DIR/CK2. See the timing waveforms in the datasheet at http://pdf1.alldatasheet.com/datasheet-pdf/view/63469/HITACHI/HA13532NT.html.

Do you think I will be able to power it through the 5V pin on the arduino? I could not find a max current rating for that pin.  Would it have to be powered with a power adapter? as opposed to being powered via usb

If I am looking at the right datasheet, the controller chip has an operating range of 10 to 27.6 volts but accepts 5v logic inputs. I'd look for markings on the motor to find its type, or failing that, try it with 12v.

I havent been able to find the exact data sheet for this driver, but I don't need to do anything complicated with it.  I just need it to spin at a constant speed, so I can probably mess around with the supply voltage and CLK inputs, but I am pretty unfamiliar with driving three phase motors and wouldnt really know how to start with this one.

Try looking up (on Google) drivers for brushless DC motors, as opposed to three-phase motors. They're similar, but the name brushless DC motor will get you closer to what you need. Three phase motors are generally much bigger and used on three-phase AC industrial power supplies.

Well thanks for the help all, but I have found a simpler solution.  Applying 12V to the red and black makes it spin.  Success!
