Abstract
The electric motor consists of a rotor fitted with permanent magnets and comprises a stator the armature of which is made up of two parts: a stack of laminations forming round teeth and a solid tube-shaped field frame made of a material of the stainless steel kind enveloping the said stack of laminations. This armature constitutes a non-disengageable braking system that produces a damping effect in the face of possible movements of its rotor which are brought about and/or imposed by the members with which it collaborates. This motor can be used for driving a roto-linear actuator device with satellite rollers which is used as an actuator for maneuvering the control surfaces of an aircraft, for example an aileron.
