Electric motor, e.g. servomotor for machine, has shorter axial overhang of centering collar over motor flange than motor shaft over centering collar

摘要

A centering collar (4) is arranged on a motor flange (3) coaxial to the motor shaft (5) on the output side. The axial overhang (b) of the centering collar over the motor flange amounts to approximately 20 per cent or more of the overhang (a) of the motor shaft over the centering collar. The inside of the centering collar is connected to the inside of the motor housing. A bearing for the motor shaft is provided inside the centering collar.
