Beschreibung
Zusammenfassung:	The present invention provides a tubular linear actuator, comprising: a tubular coil assembly comprising multiple tubular coils arranged next to each other in longitudinal direction of the tubular linear actuator and concentric with respect to a longitudinal axis of the tubular linear actuator, and a magnet assembly comprising a series of permanent magnets with alternating polarization direction extending in the longitudinal direction, wherein the magnet assembly is at least partially arranged in the coil assembly and movably with respect to the coil assembly, wherein the tubular coils comprise edge windings.
