External rotor motor with integral reduction gear - has stator winding support holding gear and combined with bearing block

摘要

Small motors of the external rotor type may be used in drives for washing machines, small machine tools and similar apparatus. The construction of the reduction gear is simplified by making the stator winding support (19), the mounting foot (1) and the gear wheel bearing block (20) as one piece. The motor rotor (24) is joined to the motor shaft (21) by radial ribs (9) between the rotor circumference and a central hub. The driving end (2) of the shaft has gear teeth cut into it which mate with a driven wheel (4). Power output may be taken by belt from a pulley (10) or from a further gear wheel (5) on the output shaft (25).
