PCT No. PCT/EP96/05396 Sec. 371 Date Jun. 10, 1998 Sec. 102(e) Date Jun. 10, 1998 PCT Filed Dec. 4, 1996 PCT Pub. No. WO97/23028 PCT Pub. Date Jun. 26, 1997A synchronous linear electric motor with a secondary part that contains several permanent magnets arranged in a certain pole grid, and with a primary part that can move relative to the secondary part and whose position relative to the secondary part can be determined by a travel measurement system. For a simple determination of a commutation offset during startup of the linear motor, a mechanical marking is provided on the secondary part that has a known relationship to the pole grid of the permanent magnets. There is also a method for detecting the commutation.
