An electric motor for an electric camshaft phaser, including: a housing; a nut fixed with respect to the housing and including a first plurality of threads; a drive shaft including a second plurality of threads, a portion of which is meshed with the first plurality of threads, and including a first segment; a rotor rotationally fixed to the drive shaft, and radially surrounding the drive shaft; a stator radially surrounding the rotor, and arranged to be energized to rotate the rotor and the drive shaft; and a first blocking element. The drive shaft is rotatable with respect to the nut, and the first segment is arranged to connect to the electric camshaft phaser to rotate an output gear of the electric camshaft phaser. A rotation of the drive shaft, in a first circumferential direction, is blocked by a contact of the first blocking element with the nut.
