摘要： Proposed is a device for the transmission of signals between components (22, 19) fitted so that they can move relative to each other. Part of a first conductor (14) is housed in a first component (22) while part of a second conductor (15) is located in a second component (19) which is mounted on a bearing (21) so that it can rotate with respect to the first component (22). The bearing (21) is electrically insulated from the components (19, 22) by an insulating element (42) and an insulating sleeve (39). The first conductor (14) and the second conductor (15) are connected electrically to each other through the bearing (21), thus establishing permanent contact between the first conductor (14) and the second conductor (15).

摘要： The invention relates to a brake device for an electric motor, comprising a rotor (10) and a stator, especially for a direct-current series-wound motor. Said device comprises a brake element (20) which can be displaced between a brake position and an operating position. A brake shoe (30) disposed on the brake element (20), brakes the rotor (10) in the brake position. According to the invention, the brake shoe (30) is disposed on the discharge side on the brake element (20) in relation to the rotational direction of the rotor (10).

摘要： The invention relates to an electric motor with electromagnetic brake which is used notably for an angle grinder and comprises a stator (11) having at least one pole pair. The at least one first pole (14) has a pole shoe (15) facing inwards towards the rotor circumference and is surrounded by a stator winding (20). Said pole (14) houses a brake device (22) which serves to brake a rotor (12) and comprises a brake element (23) which via the magnetic field of the stator winding (20) can be adjusted against a brake force (33). According to the invention the brake element (23) is configured as a rocker which is eccentrically subjected to the brake force (33). Owing to the eccentric force application the brake element (23) can be arranged with a release arm (30) in the magnetic flux of the stator winding (20) in such a way that a high release torque can be obtained.

摘要： The invention relates to a commutator comprising a cylindrical collector (1) arranged on a motor-rotor shaft and contacting means (4, 5) which come into contact with at least two out of several contact blades (3) which are predisposed on the collector (1) during rotation of the collector (1) such that an electrical connection is established between the respective contact blades (3) and external power supply points (21, 22). The commutator is especially resistant to wear and tear such that the contacting means are made of at least two electrically conductive cylinders (4, 5) which are arranged behind each other in an axial direction of the collector (1). The longitudinal axes thereof (6, 7) are arranged parallel to the longitudinal axis (2) of the collector (1) and the at least two cylinders (4, 5) are placed relative to the collector (1) and have a diameter such that the collector (1) rolls off the at least two cylinders (4, 5) during the rotation thereof via the internal surfaces (8) or the external surfaces and each of the provided cylinders (4, 5) exclusively comes into contact with a blade (3) of the collector (3).

摘要： The invention relates to a brake device for an electric motor consisting of a stator (14, 16, 18) and a rotor (10), in particular for a serial direct current motor. The inventive brake device comprises a brake element which is displaceable between the operation and brake positions thereof according to a magnetic flux in the stator (14, 16, 18). An air gap (32) is arranged between said brake element (20) and the stator (14, 16, 18). Said brake device also comprises a short circuit ring (38) for suppressing mechanical vibrations. According to said invention, the short circuit ring (38) is inclined with respect to the air gap (32) between the stator (14, 16, 18) and the brake element (20).

摘要： The invention relates to a motor-driven portable power tool, particularly an angle grinder (10), comprising a housing (15) that houses a working spindle (17) having a spindle brake (21), on which a disc-shaped tool (43) having a central borehole (49) that overlaps the working spindle (17) with play can be tightened between an inner flange (39) and an outer flange (41). As the rotating working spindle (17) is braked, the tightening pressure exerted onto the tool (43) can be automatically increased so that, in the event of inertia-related residual rotation of the tool (43), wedge means (53, 55) can rotate therewith and can slide against one another, and it is attempted to reduce the axial distance of the inner flange (39) from the tool (43) or from the outer flange (41). The aim of the invention is to provide a portable power tool of the aforementioned type that can be manufactured in a functionally reliable and cost-effective manner. To this end, the working spindle (17), itself, supports, at least in part, first wedge means (53), and the inner flange (39) can, with corresponding second wedge means (55), be supported on the first wedge means (53) of the working spindle (17), and can be captively fixed thereto with axial play and torsional backlash.
