A starter for starting an internal combustion engine has an electric starter motor, which has a drive shaft provided with an external toothing, a pinion shaft bearing a pinion, and a clutch element of a roller-type overrunning clutch situated between the drive shaft and the pinion shaft. The clutch element has an internal toothing mating with the external toothing of the drive shaft and is shiftable together with the pinion shaft away from the starter motor in the axial direction of the drive shaft into a meshing position in which the pinion mates with a gear wheel or ring gear of the internal combustion engine. The starter also has a device provided for directly supporting the pinion shaft on a section of the external toothing of the drive shaft facing away from the starter motor.

A starter for an internal combustion engine, particularly for an internal combustion engine of a motor vehicle, having a housing, on which a mounting flange is developed that can be associated with the internal combustion engine, at least one insulating part being associated with the mounting flange, such that no electrical connection exists between the starter and the internal combustion engine. An internal combustion engine, particularly for a motor vehicle, has a starter as described above. A retaining flange for an electric motor, particularly for a starter of a motor vehicle, the retaining flange being developed as an insulating part, and is made up at least partially of an electrically insulating material and/or has at least one electrically insulating insulating element situated on the retaining flange.

An electric motor with an electromagnetic brake is disclosed, particularly for use in an angle grinder, which has a stator having at least one pole pair, in which at least one pole has a pole shoe which points to the inside towards the rotor periphery and is surrounded by a stator winding. The pole accommodates the brake means for braking of the rotor of the electric motor. The brake element can be adjusted against the braking force by the magnetic field of the stator winding when the motor is activated. The brake element is constructed of magnetically conductive material as a rocker which is exposed to the braking force off-center of the swivel axis of the brake element. As a result of the off-center application of force the brake element having a disengagement arm can be arranged in the magnetic flux of the stator winding such that a high disengagement moment can be achieved and rapid braking can occur at shutoff.
