Abstract: A scooter motor includes a stator unit, a rotor unit and a brake unit. The stator unit is fixedly mounted on the fixed shaft of the motor, and the rotor unit is rotatably mounted on the fixed shaft. The brake unit includes a friction plate component and an electromagnetic clutch component. The electromagnetic clutch component is configured to drive the friction plate component to press to brake. According to the embodiment of the present invention, the scooter motor drives the rotor unit to rotate by the cooperation between the stator unit and the rotor unit to drive the scooter, additionally, the stator unit controls the rotation of the rotor unit by using the friction plate component and the electromagnetic clutch component to realize the braking of the scooter.

Abstract: The present disclosure relates to the field of outboard engines, particularly to a direct-drive electric outboard engine and an outboard engine system for alleviating the problem of the existing outboard engines, i.e., incapability of simultaneously meeting requirements on rev and torque of different types of ships. The direct-drive electric outboard engine includes an external rotor mechanism and a stator mechanism; wherein the external rotor mechanism includes an external stator and an impeller; the external rotor is located outside the stator mechanism; and the impeller is located outside the external rotor.

Abstract: A folding wheelchair, including a back frame a seat frame a lower frame, two rear wheel assemblies, two front wheel assemblies and an armrest; the armrest and the seat frame are hingedly connected to the back frame from top to bottom in a sequence; the two front wheel assemblies is connected to the lower frame; a sliding guide rail is provided between one end of the seat frame and each rear wheel assembly, and is provided with a sliding block thereon in a sliding fit manner; the sliding block is hingedly connected to a lower end of the back frame and the lower frame or the lower end of the back frame is hingedly connected to the sliding block and the lower frame; or the lower frame is hingedly connected to the lower end of the back frame and the sliding block The folding wheelchair is safe and reliable touse, and can be folded smoothly and quickly; in addition, the folded wheelchair has a small size, and is convenient to lean, against a wall, occupies a small space in a vehicle trunk or under a bed, and is co
