Abstract
The stators of collectorless d.c. motors are securely connected with the bearing support member, and/or with the fastening flange. The printed circuit board with the electronic components for the commutation is arranged for space reasons in collectorless d.c. motors between the fastening flange and the stator. This type of construction makes impossible an exchange of, for example, defective components. According to this invention, a removable stator is proposed which is retained and secured by means of only a spring element.
