Abstract
The invention relates to a monophase electromagnetic actuator which includes a rotor (1) with a cylindrical magnetized section (5) divided into two N poles transversely magnetized in alternate directions. The actuator also includes a stator structure consisting of a first magnetic circuit (2) and a second magnetic circuit (3), which are joined only by non-magnetic linking parts. Application: miniature actuators for precision and instrumentation work.
