ELECTRIC MOTOR FOR ROTO-LINEAR ACTUATOR

摘要

The electric motor consists of a rotor (7) fitted with permanent magnets (12) and comprises a stator (11) the armature of which is made up of two parts: a stack of laminations forming round teeth (14) and a solid tube-shaped field frame (15) 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 (7) 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.
