I wrote the formulas for all that and calculated the table below

Parameters are:
Motor nominal Voltage: 208VAC
Motor nominal Frequency: 50Hz
Motor rated Slip: 70RPM
Battery cut out voltage: 320VDC

Notice how having a variable slip, with the aim of keeping rotor power constant above nameplate, can attain a larger output torque. There was a topic on DIY car forums where we discussed this 2 years ago.
