3 Phase Induction Motors in Cars.
That would be most "DIY" EV cars. Because most (maybe all) production EV cars use 3 phase motors. Three phase drives (both induction and PM) require a bit more, hmmm, let''s call it sophistication than DC drives. The controller is more complex and needs to be compatible with the particular motor. DC drives are less sensitive in this regard.

Is it possible to buy a three phase battery system?
@MARSH_8195 The answer is no, the Enphase battery system can''t support a 3-phase load like a heat pump during a grid outage.. Even though the System Controller 3 can now support a battery on each phase, and these will all operate during an outage, the three phases will not be synchronised 120 degrees apart the way the grid is and the way a 3-phase motor requires.

batteries
Let''s look at power. You say the motor needs 3.1V and 1.2A per phase. I am not sure how to parse that exactly, but to get a rough idea, let''s just say it is 3.1V RMS and 1.2A RMS per phase. That means the total power is 3.1 * 1.2 * sqrt(3) = 6.4 Watts. That is probably not exactly the right equation. But it should be ballpark.

Run Your 3 Phase Motor From A Single Phase (230VAC) Supply!
This means many motors can be swapped out for newer more efficient motors easily. It also allows you to install a 3 phase motor that can be configured in Delta, this can subsequently be run from an inverter powered by a single-phase 230VAC supply. These inverters will allow you to use a 3 phase motor up to 4kW or 18A from a 230VAC supply!

3 phase AC motor 220V powered from 12V battery
Battery capacity 7-20Ah. Required motor power is 50-100W (torque I think >0.2Nm). Because of outdoor usage I need IP66 or so. Price is also essential. I did not find any 12V DC motors and seems that 3 phase AC
Is there a 208 WYE 3 phase charging option? | Tesla Motors Club
208V 3-Phase Wye-Connected With a Wye-connected secondary, any two of the legs can be used to provide 208V to the Wall Connector. For example, L1 and L2, or L1 and L3, or L2 and L3.
Powering a 3 phase 230VAC motor with 28 12V batteries wired in ceries
A ''12V'' lead-acid battery can have 2.2V/cell (or more) = 13.2V at the end of a recharge cycle. 13.2 x 28 = 370Vdc, so you''re over the maximum input. Whilst the freshly charged battery terminal voltage will drop quickly upon load, it will be >357V for a non-trivial period of time. The blower appears to be driven by a 3-phase induction motor
power supply
The common solution is not to use battery power inverters but AC to DC to AC inverter "variable frequency drives" or VFD''s. These start from DC and accelerate line frequency ( or less to the desired RPM ) by raising sinusoidal 3 phase V with f to keep V/f constant and thus increase current with RPM to prevent high acceleration currents that occur from full voltage to
Understanding Phases of Electric Motors: Single Phase vs. Three Phase
Which Motor Should You Choose? The choice between a single-phase and three-phase motor depends largely on your specific needs: For residential or small commercial applications where power demands are lower, and a standard electrical supply is available, single-phase motors are typically the best option due to their lower cost and ease of use.; For industrial or large

Powerwall: Three-phase house | Tesla Motors Club
If you have a 3-phase inverter, it generates power across all 3 phases and can be used by all 3 phases. If the PW is installed on only 1 phase of the 3-phase system, then it can only capture 1/3 of the generated power. But the other 2/3 is available for use on the other phases, so it is not lost.
