A magnetic actuator for a magnetic suspension system

A magnetic suspension system comprising:

• at least one magnetic actuator for magnetically levitating an object,
• equipment for generating a position signal indicative of a position of the object with respect to a reference position of the object, and
• a controller for controlling electric currents of the coils of the magnetic actuator based on the position signal,
• wherein the at least one magnetic actuator comprises:
• a core section having an annular yoke and radially directed teeth joining the annular yoke,
• coils having radially directed magnetic axes and surrounding the radially directed teeth, and
• a mechanical structure having a first section attached to the annular yoke and extending axially from the annular yoke and a second section joining the first section and extending radially from the first section in a same direction in which the radially directed teeth extend radially from the annular yoke,
• wherein the first section is suitable for conducting magnetic flux axially and the second section is suitable for conducting the magnetic flux radially in a direction opposite to a direction of the magnetic flux in the radially directed teeth, and wherein the magnetic actuator comprises a mechanical safety bearing that is, in an axial direction of the magnetic actuator, between the second section of the mechanical structure and the radially directed teeth of the core section.
