Electromagnetic linear driving mechanism has a driving coil unit forming a stator with driving coils and a rotor moving inside the driving coil unit

摘要

Excited by an adjusting voltage, a driving coil unit (18) forming a stator consists of two or more driving coils (17) fitted behind each other in the driving direction. A rotor (11) moving inside the driving coil unit in the driving direction contains permanent magnets (13-15). An extra exploring coil unit (19) with two equal coil areas (20,21) runs along the whole driving coil unit.
