I have same problem regarding the wiring of Motor. Although this motor is manufactured in China, I still do not get timely response from the vendor LINIX. It seems that LINIX has upgraded the series of 45ZWN with 40ZWN and 60ZWN. So their recent document can not explain our situation now. I will keep try and share the feedback to you in my blog.

But do not worry about the wiring. There are 3 wires with larger diameter with different color, that is the drive wires for motors. The order does not matter, since it only influence the direction or rotary. If you are not sure of it, you can connected according to the pic for demo page for FRDM-KV31. The rest wire are colored according to some Chinese Practice, I will share with you when I find right documents.

The problem to me is that the motor is too heave for my design, if I still try to installed it vertically. I have to revise my design to solve this tough problem.

Hope this can be of some help.

If you take the bottom off of the motor housing, it's easy to see how it's wired. The three thicker wires are the three phases, the thinner 5 wires are: Red=hall effect 5VDC, Black=hall effect gnd, the other three are the hall effect sensors:

Shouldn't be hard to identify 3 phase wires using a multimeter. Or you can spin the motor with some other motor (e.g. drill) and poke the pins with an oscilloscope observing back-EMF. It would be interesting anyway to see what back-EMF looks like on this motor. Whether it is indeed sinusoidal (PMSM motor) or trapezoidal (BLDC motor).
