Well, we're not even sure if this machine is a motor or a generator. Perhaps the OP could provide the eBay number or link.

I see no "problems". Without increasing the amount of copper, you could not change the armature winding to get more torque. The BEMF is likely appropriate for the application hence the reason this winding was chosen. And any armature inductance contributes to reactance with the alternating current in the armature circuit which is no problem. Extracting any other than shaft power from an intermittent duty motor is a losing proposition. If the machine is a generator, you're already taking all the generated electrical power.
