Electric scooter motor reversible?

[John Doe]

I have not found it on the web, but the part number is
XYDJ09072117
It uses this controller.
http://www.curriestore.com/731-ezip-controller.html
"Controller, 24v30a BG 5pin, TO/Charge Cut, (08A version)"

Basically the same as this 500 W motor.

Does just reversing the polarity of the wires going to the motor
cause it to run backwards but perfectly otherwise?

Thanks.

It looks like a simple brushed DC motor:

This kind of a motor will go backwards but maybe not very well. A high
efficiency motor has the brushes aligned to compensate for field
distortion at operating speed.

They are BLDC motors and controllers- 3 phase, essentially. Swapping any 2
of the 3 wires will reverse the motor. DON'T reverse the battery , it will
all go bang!!! You'd never get the wattage from that size stepper...
I'd suggest that particular motor is internally geared....

Only two wires go to the motor.

The motor is the 750 W version of this 500 W motor.

Will it run as efficiently in reverse, by simply switching the
wires? Someone else is suggesting that the brushes might be
aligned better for forward motion. I need to do some metal work
that depends on whether the motor can run in reverse exactly the
same as forward.

Thanks.

There are no brushes LOL... BLDC = B rush L ess DC motor.
They run in either direction with no reduction in power.

That is a chinese POS motor that is *rated* at 336 watts max. It is
chinese, and therefor you must derate it by a factor of about 75%. If
you are using a chinese motor, no one here can tell you what will
happen if you reverse the voltage to it.

It is unlikely that that motor has any optimization...

Yes I know, but that is not the subject. If you have a better
motor (same size and mounting) that will live up to your
standards, please feel free to send it to me.

Why is that?

Are/were you drunk?

I gave you a direct link (right there, above this) to a brief
description of the product on the distributor's website. It says
"brush". Even the link says "DC_Brush_Motor".
