Abstract
The invention relates to an electric motor having a motor shaft on which motor pinion is or can be placed, to such a motor pinion, and to a method for fastening the motor pinion to the motor shaft. The starting point is a motor pinion having a shaft accommodating section for placement on and fastening to a motor shaft in rotationally rigid fashion, the shaft accommodating section having a wall for encompassing the motor shaft. The advantageous fastening comes about in that at least a part of the wall is fashioned so as to be constrictable for restraining the motor shaft. In mounting, the wall is compressed against the motor shaft by a nut, the wall advantageously having an increasing external circumference.
