SWXB - electric datasheet and more?

[Moszuke]

Hello guys!

I have been searching through this forum for information, but its became more and more complicated to me..

I have bought an used BF SWXB motor 36V DC, 250Watts

this motor has 3 thick and 5 thin wires (yellow-green-blue and yellow-green-blue +red,black)

can you tell me or link me full datasheet for this motor? i have been searching through google, got some drawings from the motor parameter (height, weight, widht etc)
But i would like to know something about the electric part.

from this forum i know that the 5 thin wires are the hal sensors, and somewhere you wrote that the motor can be running without sensors.
good
2of the 5thin wires is (red and black) the hall sensor power supply.

the 3 thick cable must be the motor coil with tons of amper flows through
so is this motor a 3 phase motor (3x 120° coils) and i need a controller to start playing with it?
is this motor BLDC type or ECDC?
i found this 2 type of three phase DC motor at wikipedia

so my questions:
- can it be run without sensors connected?
- what are the 3 thick wire? (are they the 3x 120°coil ?)
- IF this is a 3phase 36V DC motor, is this motor BLDC type or ECDC? or am i mixing stuff again?...
- can you show me W/Nm graph?
- do i need a controller which makes my 2pole 36V DC, to square or sinus 3 pole 36V AC?

so my questions:

- can it be run without sensors connected?

Yes with a sensorless controller.

- what are the 3 thick wire?

They are the current supplies to the coils.

- IF this is a 3phase 36V DC motor, is this motor BLDC

It is a BLDC motor.

- can you show me W/Nm graph?

I don't have a graph link, others may have though.

- do i need a controller which makes my 2pole 36V DC, to square or sinus 3 pole 36V AC?

Yes, most are square wave but there are some pure sine wave controllers which give nicer running.

There's a lot of different versions of that motor, so you can't get a data sheet unless you know which one you have.

Get a proper BLDC ebike controller for it. You should get one for sensored motors. A sine-wave one is better than a square wave one.
