  "textContent": "An electric wheel system (1000) comprises: an electric wheel part (100) including a motor (20) and an inverter (10); a first arm which connects the bottom side of the electric wheel part and a vehicle body; and a second arm which connects the top side of the electric wheel part and the vehicle body. A motor housing (24) includes a first arm connecting part (25) connected to the first arm and a second arm connecting part (26) connected to the second arm. The inverter is disposed at a position overlapping a line segment connecting the first arm connecting part and the second arm connecting part. The motor housing includes a first fan-shaped area (1) with a central angle of 120° centered on the rotation axis of a rotor and a second fan-shaped area (2) with a central angle of 240° centered on the rotation axis of the rotor. The first arm connecting part is disposed in the first fan-shaped area disposed on the bottom side of the motor housing. Electrical connecting parts (15U, 15V, 15W) between the inverter and the motor are disposed in the second fan-shaped area disposed on the top side of the motor housing.",
