ABSTRACT:
An electric starter for internal combustion engines has a drive pinion unit with gear teeth for engagement with a gear ring of the engine and is driven by an electric motor so as to rotate the engine. The motor has a rotating laminated armature and an armature shaft; the drive pinion unit is mounted on the shaft so as to be freely slidable and rotatable relative thereto, and splined drive means fixed to one end of the laminated armature engage splines on the drive pinion unit whereby to transmit drive to the latter. The drive means may take the form of an internally-splined sleeve co-operating with a tail portion of the drive pinion unit; the splines are preferably helicoidal.
