Do anyone know what motor this is?

This motor has a inscription on its side, which says:
"Tgx 250w 120swx 24v 175rpm 1hvt1107 en15194 mfaz 0414"

Do anyone know what motor this is? Or what the more shady abbrevs stands for?

Any clues would be grrrrait!

Tongxin i'll bet. Pictures please?

I assume it's 250w and 1,750rpm. Also less than 1 newton meter for torque. Need some idea what it looks like.

Tgx 250w 120swx 24v 175rpm 1hvt1107 en15194 mfaz 0414

Tgx is the manufacturer's code - possibly Tongxin, but I haven't see that on their motors.
250w is a the nominal continuous rating, but it's more a category than an actual rating.
120 is the phase angle
swx seems to be a size or power category.
24v obvious
175rpm is the no-load speed at exactly 24v
1hvt1107 is probably the model number and serial number (guess).
en15194 is the European standard for electric bikes. It has little meaning on a motor.
mfaz - not sure. Could be the production location.
0414 is the month of manufacture.

If you show a couple of photos, we can say if it's a Tongxin. AFAIK, Tongxin stopped production before 0414, so something isn't right. I heard that their production was taken over by Outrider. Maybe they're using the same Tongxin markings.

Here's a pic that might give you a clue...

You were right! It was a Tongxin. With rollers as planetaries. Red grease.

Keyde uses the same roller tech as Tongxin did.

Yes... I was under the impression that Keyde use green or blue grease...

I don't think the color of the grease matters. I use synthetic high temp disc brake wheel bearing grease from Mobil on my Xiongda and it works fine. Really quiets down the motor.Comes in a can. Oh yeah, it happens to be red.
