The suspension member extends along a longitudinal axis intended to be aligned with a rotation axis of a rotor of the electric motor. The suspension member includes multiple circular plates disposed perpendicularly to the longitudinal axis and adjacent to one another along the length of the axis, including at least one intermediate circular plate. Each intermediate circular plate is connected to each of the two plates adjacent thereto by at least three connection points. ## Claims ### Claim 1 A suspension module for an electric motor inside a tubular casing of an electromechanical actuator for a closure or sun protection facility, comprising a single-piece suspension member, extending along a longitudinal axis aligned on a rotation axis of
