Electromechanical actuators linear actuation product

The Electromechanical actuators is a linear actuation product from Moog with professional grade and ema actuator technology. The Moog linear electromechanical actuator, listed on the maker's site as model 62030, is a linear actuation product for armament equipment. Moog makes it as a compact device that converts an electrical pulse into linear force through an electromechanical mechanism, and the product line is known by the abbreviation LEMA.

The mechanism uses internal rotary solenoids that move in a plane perpendicular to the direction of the linear motion. Because of this arrangement, the actuator can only be activated by an electronic pulse, and shock or unintentional activation does not move it. The design is patented, and Moog describes it as dependable and fault-free for its size.

The figures given for the force are more than 50 pounds of linear force, with up to 60 pounds available from a relatively small unit. For an integrator this means that a compact body can drive a latch, release or locking mechanism that needs a strong push or pull, with the force coming from the solenoid stage rather than from a larger motor and gear train. The stroke of model 62030 is 0.560 in (14.21 mm), which suits short, defined movements and not continuous positioning.

For installation, the body is cylindrical with a diameter of 1.63 in (41.38 mm) and a length of 4.35 in (110.44 mm). The drive is by an electrical pulse from the host system, so the integrator must provide a suitable pulse source and a mounting that takes the reaction load of the stroke. Moog lists the actuator among its solenoid products, and a solenoid product guide and brochures are available from the maker for the electrical details.

The actuator type is electromechanical, with no hydraulic supply. Moog develops it for armament equipment, where release and arming functions must not be triggered by shock or vibration.
