A wheel hub driving device with planetary motors comprises the planetary motors and planetary mechanisms. Each planetary motor comprises a gear ring stator and a plurality of planetary rotors radially arranged on the inner side of the gear ring stator; each planetary mechanism is used for matching rotate speed and torque of each planetary motor and a wheel hub and comprises a planetary carrier, a gear ring and a plurality of planetary gears; the planetary gears are radially arranged on the inner side of each gear ring; the planetary gears are meshed with the corresponding gear rings so as to enable the planetary gears to roll along the inner peripheries of the gear rings; the planetary gears are respectively in one-to-one correspondence to the planetary rotors, and the planetary gears are respectively coaxially connected with the planetary rotors; the planetary gears are respectively rotatably connected with the planetary carriers through rotating shafts so as to enable the planetary carriers to rotate with the planetary gears relate to the gear rings. The wheel hub driving device is higher in power density, reliability and fault safety. The invention further provides a wheel power system adopting the wheel hub driving device.
