Electric motor i.e. electronically commutated-direct current external rotor motor, for motor vehicle i.e. bicycle with electric drive, has planetary gear with base that is connected with drive shaft

摘要

The electric motor (25) has a stator (1) with a predetermined region (4) for connection with a vehicle frame. A rotor (13) is mounted with respect to the stator in a rotatable manner. A planetary gear (26) has a hollow wheel (29) that is connected with the rotor and a sun wheel (27) that is connected with a hollow shaft, where a base (31) of the planetary gear is connected with a drive shaft (17). Multiple crank levers are fastened with pedals at ends of the drive shaft. The drive shaft exhibits a freewheel device (33) in a transition zone for the rotor.
