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.
http://www.curriestore.com/481-ezip-motor.html

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

Thanks.

Overall it physically resembles a stepper
motor, but it only has two wires feeding it
so it is most likely a DC motor.
Technically it could be a stepper motor with
a controller built inside somewhere also.
The specs tab on the web pages are non-functional.

There is a limit to what can be determined from
a mere photograph.

The schematics of the motor and controller
on page 3 of this didn't conclusively prove
anything except that I didn't spot a REVERSE position.

Did you?

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.
