Abstract: A brushless stepper motor is described comprising a first and a second stator (11, 12); and a rotor disc (1) that is rotatable about a rotation axis (Y). The rotor comprises two faces; and is interposed between the first and second stator, so that each face of the rotor is opposed and parallel to a stator. The rotor comprises a first circular series (SM1) of permanent magnets (7M1) arranged at constant angular-step along a first circumference concentric to the rotation axis (Y), each permanent magnet having a parallelepiped shape with a longitudinal axis (X) orthogonal to the rotation axis (Y). Each stator comprises a first constant angular-step circular series of electromagnets (2) with polar expansions (5) facing the permanent magnets of the stator disc.

Abstract: An electromagnetic linear motor comprises a tubular stator (1), which has a longitudinal axis (W), and a permanent magnet (7) with poles oriented along said axis (W) and linearly movable inside the stator (1). The stator (1) comprises at least two columns (A, B) formed by electromagnets (2), each electromagnet (2) comprising a core (U) formed by a central straight segment (4) and two end polar expansions (5) all being oriented towards and orthogonally to said axis (W). The columns are circularly arranged around said the permanent magnet (7) and mutually linearly offset along said axis (W). A compressor and a valve driven by such an electromagnetic linear motor are also disclosed.
