Linear actor with optimized inductivity and method of winding and connecting coils

A linear reluctance actor comprising:

• an axially adjustable rotor and a stator arranged coaxially thereto, and
• at least one coil arranged in the area between the stator and the rotor which is guided in a groove of the stator and which is delimited by groove webs,
• wherein a groove profile facing the groove webs is formed on the rotor, the groove walls forming an offset with each of the groove webs, and comprising power electronics for activating the at least one coil such that the rotor performs a controlled/controllable stroke due to the reluctance force in response to the activation,
• wherein the groove profile is designed to be complementary to the groove webs so that they are arranged to be approximately radially opposite to each other with a minimum offset,
• wherein the stator and the rotor are made of a magnetically conductive and/or soft magnetic material, and
• wherein the linear actor includes at least one resetting element which is designed in such a manner that during operation the rotor is brought into a specific predefined initial position after a stroke movement.
