  • MOTOR ARRANGEMENT
    Publication number: 20210288553
    Abstract: A motor arrangement includes a motor having a stator and a rotor. The rotor is rotatable relative to the stator to drive a propulsive component and is arranged radially outside the stator. The stator defines a radially inner space. Motor control components are located within the radially inner space. In one embodiment, the motor arrangement further comprises a cooling system being common to the motor and the motor control components and being located in the radially inner space. The common cooling system may use air generated by the propulsive component driven by the motor to cool the motor and the motor control components. The air from the propulsive component may be ducted into the radially inner space.
