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 manoeuvring the control surfaces of an aircraft, for example an aileron.
Claims6
An electric motor wherein that it comprises a continuous, non-disengageable, constantly operational braking system, directly linked to its structure, said braking system absorbs a portion of the energy which said electric motor or a driving mechanism associated with said electric motor, depending on the case, is capable of providing.
