Plettenberg Big Maximum (HP 220/40/A2 S P4 Car)
is a 4-pole motor.
bearings are rated at 70000 RPM, but not the motor efficiency or power...

Motor specs at 18V:
Power - 1271W
Current draw - 70.3A
RPM - 37688
Torque -28.9Ncm
Efficiency 89.8%

max efficiency (91.5%) at ~45A / ~40000RPM / ~18Ncm

Motor can be pushed towards 2000W but efficiency falling dramatically, though great cooling system keeps it from falling apart.
