the relationship of amps to rpms in an induction motor
Speed:

The speed is measured in RPM.  60 Hz excitation voltage corresponds to 3600 RPM.  The mechanical speed can be further reduced by using a motor with higher magnetic pole count.  Two pole motor has the same mechanical frequency as the excitation voltage.  Four pole motor will have half the frequency, six-pole motor will have a third of the frequency.

Induction machines slip behind the excitation frequency by definition.  Typical slips are 0-5%.  The higher the mechanical loading, the higher the slip.

7000 RPM is not possible without either a variable frequency drive (VFD) or a gearbox.

Power

For simplicity, one can assume that the mechanical power out is about 90% of the electrical power in.  2 kW motor can therefore draw ~2.2 kW of real power.  With 3-phase 220V line voltage the current would be:

$$V_{phase} = \frac{V_{line}}{\sqrt3} = 127 Vrms$$

$$I_{phase} = \frac{P}{3V} = \frac{2200 W}{127 V*3} = 5.8 Arms$$
