INTRODUCTION TECHNICAL FEATURES Moog MEMA Performance Characteristics Having collaborated with a several industrial machine designers, Moog engineers understand the critical role that application sizing process plays in overall machine design. The MEMA have been developed keeping this in consideration. The typical force/speed characteristics of the MEMA are shown below: Force [kn] 3 MEMA capabilities The below illustration provides an overview of the MEMA capabilities.

For life estimation please refer to the following pages. 4 3 Size 3 Maximum force Curve This curve reflects the motor torque available with a % duty cycle ( out of s). It is based on years of practical industry experience and is useful for typical servo applications. Size Size,,,,3,4,,,7 Continuous force Curve This curve illustrates the motor torque available at % duty cycle under the following conditions: Operation in still air with ambient temperatures up to 4 C Winding temperature measure up to C over ambient for resolver feedback motors Motor front flange attached to a steel mounting plate measuring minimum 3 x 3 x mm Rev., September 4
INTRODUCTION TECHNICAL FEATURES MEMA High force L7P Drawings Motor Gearbox 3 Torque limiter 4 Bearing MEMA High speed L7B Drawings 3 4 Screw Rod 7 Housing 7 DEFINITIONS Continuous Stall Force: Force produced by the servoactuator at the continuous servomotor torque and at zero speed. Continuous force declines as servomotor speed increases. Consult performance curves for force rating at higher speeds. Continuous servomotor torque is limited by temperature and thus, the continuous force will be reduced with ambient temperatures above C. Peak Stall Force: Force produced by the servoactuator at the peak servomotor torque and at zero speed. Peak force declines as servomotor speed increases. Consult performance curves for force rating at higher speeds. Peak force can be held only for short durations (typically less than minute) after which a cool down period at less than the continuous rating is required. Brake Holding Force: Maximum force that the optional brake will hold stationary. Brake should not be used to stop a moving servoactuator as damage to the brake will result. Maximum Static Load: Mechanical load limit of the servoactuator components. This is a limitation of the structural components of the servoactuator. Motor 9 Bearing Screw Rod Housing 9 Dynamic Load Rating: The load at which the estimated life of a ballscrew or bearing will be million revolutions. Maximum Speed: The maximum linear speed for the servoactuator. The available force at maximum speed is significantly less than the Stall Forces. Consult the Performance curves for Force/Speed relationship. Fully Customized Designs Support Unique Application Requirements Moog can tailor actuators to the exact specifications or requirements of a machine including custom specifications for the following: Connector configuration (including pigtail) Feedback device Design for unique environments including high temperature, high shock levels, oil and water immersion Special painting Special mounting interface Special mounting rodend Accuracy: The ability of a positioning system to move exactly to a commanded position. Repeatability: The ability of a positioning system to return to the same point from the same direction with the same load. Resolution: The smallest positioning increment possible. Anti-rotation device: Device used to prevent the nut spin movement. An anti-rotation device is essential for the properly work of the actuator Lead Accuracy: The maximum deviation from nominal lead over specified interval. Rev., September 4 7
