    Abstract: A linear propulsion machine and system (10) is disclosed that includes a stator (30) having a plurality of teeth (34) and a mover (32) moveable in a linear direction along the stator (30). The mover may include a plurality of spaced apart ferromagnetic strata (40), a plurality of slots (42), a plurality of wire coils (44), and a plurality of magnet layers (46). Each of the slots (42) may be adjacent to at least one of the strata (40). Each coil (44) may be disposed in a slot (42). Each magnet layer (46) may be sandwiched between strata (40) and disposed inside one of the plurality of coils (44). Each coil (44) is disposed perpendicularly to the direction of magnetic flux of the magnet layer (46) around which the coil (44) is wound. In an embodiment, the teeth (34) or the magnet layer (46) may be disposed at an angle.

    Abstract: An encoder assembly is disclosed. The encoder assembly comprises a motor having a rotor, and an encoder. The encoder comprises an encoder wheel axially coupled to the rotor, a first sensor configured to detect a first velocity at which a portion of the encoder wheel moves relative to the first sensor, and a second sensor configured to detect a second velocity at which a portion of the encoder wheel moves relative to the second sensor, the first sensor and the second sensor positioned approximately 180 degrees apart from each other about an axis of rotation of the rotor.
