In an electric motor intended to be fixed to a printed circuit board, provision is made for it to have at least one expanding dowel ( ), for it to be possible for the motor ( ) to be fixed to a printed circuit board ( ) by the expanding dowel or dowels ( ) being expanded, and by it being possible for the expanding dowel or dowels ( ) to be secured at least by a pin ( ).

In a control device for manually inputting information into a device, having a final control element whose position can be changed under the effect of an activation force and which is connected to a converter for generating electrical signals which characterize the position of the final control element, and having a motor element which is connected to the final control element and which exerts, under the control of the electrical signals, a force on the final control element, the size and direction of which force is dependent on the position of the final control element and/or on the information which is to be input, there is provision for the converter to be composed of the rotor ( ) of the motor element and sensors ( ) which respectively emit an electrical signal as a function of the position of the rotor.

A coil assembly has a coil form on which the coil winding is arranged as well as a method of contacting the coil assembly on a support member. The coil assembly is easy to produce and also permits electrical contacting, namely, the provision of electrical contacts between terminals of the coil and an external circuit in a simple and reliable manner. The coil assembly has a coil form on which two contact feet are arranged, the ends of the coil winding being fastened to the respective contact feet.

An electric motor has two exciter windings, independent of each other, on a stator, by which windings a resultant magnetic field can be produced. The motor includes a permanently magnetized rotor which has at least one pair of poles, the rotor changing its position as a function of the magnetic field, and the rotor being arranged axially on a rotor shaft. In the case of an electric motor which is of a small size and easy to manufacture, the stator is developed with several arms, and has an opening present at the center to receive the rotor. The individual arms are arranged around the opening and, there are, two pairs of opposite arms. The opposite arms are so bent towards each other so that, upon their receiving a respective exciter winding, they produce magnetic vectors which are perpendicular to each other.
