, what determines the speed?

Basically the motor pushes more air but slower with the 825 rpm motor.
If you try to use a 1075 motor and push that fan blade with more pitch it will overheat unless you were to really oversize the motor (1/4 to 1/3 not enought).
The bottom line is you need to have the RPM's of the new motor the same as the original motor.
825 RPM motors cost about twice as much as 1075 RPM motors.
Make sure to install the fan blade properly. If it is too far away from the motor it will generate more resistance, which will overload the motor even more.
Now with the 825rpm motor, the condenser should feel warm instead of burning hot
