    Abstract: In order to pick up in a simple manner which is reliable, and under rough operating conditions, a rotation of the rotor in a miniature motor excited by permanent magnets with magnet segments at a tangential distance with magnet segments distributed at the bore circumference of the stator, it is proposed to arrange in at least one pole gap between the magnet segment a measuring coil. A signal is induced by the pulsation of the stray field due to rotation of the rotor. The measuring coil is advantageously arranged in a non-magnetic, preferably plastic support body held between the individual poles or the magnet segments respectively.

    Abstract: In order to improve the interference suppression of an electric-motor auxiliary motor-vehicle drive, particularly in the direction of electromagnetic compatibility (EMV), a protective circuit branch (2, 3) with two Zener diodes (D1; D2) or with one varistor (V1) is provided parallel to the armature circuit branch (1) of the commutator motor (M), where, for reducing the number of external solder joints, the Zener-diodes (D1; D2) or the varistor (V1) are combined with the interference suppression capacitors (C1; C2) in common integration component (6) which has only three external terminals.

    Abstract: A pneumatic hammer comprises a rigid unit of construction, which comprises a housing, a handle, an operating cylinder resiliently supported in the housing, and a tool holder for receiving a tool movable in a striking direction by the operating cylinder. The operating cylinder is axially movable in the housing relative to the tool holder. Compressed air is supplied to the operating cylinder, and a damping spring acts upon the tool holder in a direction opposite to the striking direction.

    Abstract: A dc commutator motor can be switched off when the motor rotor is short-circuited by the rotor's coming to a halt, by an operating switch (10). The switch is provided in the line connecting the brushes to a radio suppression network in a compact and simple design. The switch is operated by an ac voltage induced when the motor is running, with a frequency corresponding to the motor speed. A sensing winding connected to the operating switch for inducing the operating ac voltage is wound preferably around a radio interference suppression choke of the radio suppression network.

    Abstract: In a radial blower with two blower wheels (2, 3) fastened axially in tandem on one shaft end each of the interposed drive motor (b 1) with one blower blade circle (21, 31 respectively) held at a radial distance from the hub (26, 36) on the blower shaft side, the operating noise is to be reduced by simple arrangement while maintaining a high output yield; to this end it is proposed to connect the blower blade ring (21 and 31 respectively) of each blower wheel (2, 3) via spokes (22 to 25, and 32 to 35 respectively) leaving free tangential spaces and to arrange the spokes (22 to 25) of the one blower wheel (2) relative to the spokes (32 to 35) of the other blower wheel, as seen in the axial direction (blower shaft 4) in the gaps (circumferential angle of rotation .alpha.) relative to each other in the circumferential direction.
