SLA7044M

You can run any UNIpolar motor with that IC up to 3A, that means motors with 5, 6 or 8 wires can be used with proper wiring. 5A is the maximum it can handle for a very short period of time. As for voltage, if you are using 24V power supply it will work even with 12V motors, but no fast rotation, yours is 3.2V so it will work nicely.
And it does not have to be the exact replacement, it will work with most motors ( even bigger or smaller in size ), but avoid high voltage ones as they will limit the rotation speed a lot, and the current for your case can be anything from 2 to 3.5A, on the motors. You can also change a single resistor on the board the 7044 is and change the current going to the motor if you need to.
