Advantages of Electro-Mechanical Actuators
By Bob Wojcik
Sometimes Electro-Mechanical Linear Actuators (EMA) offer advantages that hydraulic or pneumatic linear actuators (such as cylinders) are unable to provide. These advantages may include:
Performance
- Long lasting performance
- Extended reliability
- Integrated design
- Reduced component count
- Pre-engineered system including actuator, servo drive and software
- Easy set up and installation
Precision
- More accurate motion control
- Low inertia motor for higher acceleration
- Lower noise
Efficiency
- Reduced maintenance
- Reduced operating costs
- Reduced energy consumption
- Full range of options, sizes, and configurations
- No leaks
Moog, Inc., with 60+ years of experience and expertise in the servo and proportional valve electronics development, has developed a line of Electro-Mechanical Linear Actuators that rival traditional hydraulic linear actuators in force and velocity performance. The Moog EMA can provide position accuracy to +/- 0.001” and speeds up to 63 inches/second. With four frame sizes and two styles, the EMA offer up to 33,700 pounds force in strokes up to 98 inches.
Moog’s MaxForce Pre-Engineered Electric Linear Actuation Solution is currently utilized in many industries requiring a high performance solution, such as:
• Pressing systems, such as bearings being pressed into housings, in the manufacturing industry
• Damper control in the power generation industry
• Edge guide systems for web control in the plastic, sheet metal, and paper industries
• Synchronized bottle filling in the food and beverage industry
• Sintering pusher furnace in the powder metal industry
• Tensioning in the plastics industry
• Walking beam or parts movement in the automotive assembly line
