Abstract: A closure latch assembly includes a latch mechanism having a pawl moveable between a ratchet holding position, whereat a ratchet is maintained in a striker capture position, and a ratchet release position, whereat the ratchet is biased toward a striker release position. An electromagnetic actuator includes a first member, a second member, a plurality of permanent magnets fixed to one of the first and second members and a plurality of electromagnetic coils fixed to the other of the first and second members. The electromagnetic coils are energizable to attract and repel the plurality of permanent magnets to move the first member relative to the second member, whereupon the relative movement causes at least one of the following actuations: movement of the pawl between the ratchet holding and ratchet release positions; locking the pawl against movement from the ratchet holding position to the ratchet release position; and cinching the ratchet in the striker capture position.
