A camshaft adjuster for adjusting the phase angle between a crankshaft and a camshaft of an internal combustion engine comprises an actuator, in particular, an electric motor, and an adjustment module, which comprises a drive element, which can be driven by the crankshaft, and an output element, which can be rotated relative to the drive element to a limited extent and which is provided to be securely coupled to the camshaft, wherein a signal generator, which is arranged so as to be fixed in position on the internal combustion engine and which has an inductance, is inductively coupled to a measurement circuit, which is integrated into the adjustment module and which has at least one resonant circuit component having electrical properties that depend on the said phase angle.

An electrically-actuated camshaft phaser including an electrically-actuated lock that includes a planetary gear assembly having a camshaft ring gear configured to be connected to a camshaft, a sprocket ring gear configured to receive rotational input from a crankshaft, and one or more planet gears engaging the camshaft ring gear and the sprocket ring gear, wherein the planetary gear assembly changes the angular position of the camshaft relative to the crankshaft; an electric motor, coupled to the planetary gear assembly, and a solenoid, wherein the electric motor controls the relative angular position of the crankshaft relative to the camshaft and the solenoid selectively moves a mechanical connection into locking engagement thereby preventing relative movement between the camshaft relative to the crankshaft.

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.

An adjusting device, in particular for adjustment of a camshaft of an internal combustion engine, is disclosed. The adjusting device includes a brake unit which has at least one brake disc and at least one electromagnet for actuating the brake unit.

A cam phasing control motor assembly, including: an electric motor with a hollow drive shaft; an actuating pin passing through the hollow drive shaft; an engagement feature; and a displacement assembly. For a camshaft locking mode: the displacement assembly displaces the actuating pin in a first axial direction to non-rotatably connect the engagement feature with a bolt non-rotatably connected to a camshaft; and the camshaft is arranged to non-rotatably connect to an input gear for a gearbox phasing unit, the input gear arranged to receive torque from an engine. For a phase adjusting mode: the displacement assembly displaces the actuating pin in a second axial direction, opposite the first axial direction, to disconnect the engagement feature from the bolt; and the camshaft is arranged to rotate with respect to the input gear.

A system (42) including a phaser (28), a motor (38), and a controller (40) for controlling the phase between a camshaft (18) and a crankshaft (16) of an engine (10). The phaser (28) is attached to the camshaft (18), is in communication with the crankshaft (16), and is configured to adjust the phase of the camshaft (18). The motor (38) actuates the phaser (28) and is operatively attached to and in communication with the phaser (28) such that rotation of the crankshaft (16) back-drives the motor (38) to subsequently generate a signal. The controller (40) is in electrical communication with the motor (38), is responsive to the signal, and uses the signal to determine the rotational speed of the motor (38) to thereby commutate the motor (38) and subsequently drive the motor (38) so as to actuate the phaser (28) and control the phase of the camshaft (18).
