Electric Cylinders

Electric Cylinders are electric drive devices that convert rotary motion of motor into linear motion of  push rod. Electric cylinder actuator are electromechanical devices that convert rotational motion from an electric motor into linear motion.

Technical breakdown of TallMan Robotics Electric Cylinders

This electric cylinder converts motor rotation into linear motion using a ballscrew or leadscrew inside a sealed tube. The motor mounts inline or parallel via a belt or gearbox. A piston rod extends and retracts from the tube. Guide bushings or recirculating ball bearings support the rod. Stroke lengths range 50 mm to 1000 mm.

Key components of electric cylinder actuator include:

Electric Motor: Typically servo or stepper motors for precise control.
Lead/Ball Screw: Converts rotation to linear movement; ball screws offer higher efficiency, lead screws are cost-effective.
Cylinder Housing: Protects internal components and provides structural integrity.

FAQs about Electric Cylinders

1. What is the difference between electric cylinder and linear actuator?
   No difference. Electric cylinder is a type of linear actuator. The term “cylinder” mimics pneumatic cylinder shape. Both convert rotary to linear motion. Electric cylinder emphasizes the rod style output.
2. How does Motor-Driven Cylinder replace a pneumatic cylinder?
   Mount the electric cylinder in same footprint. Connect 24V DC or AC power instead of compressed air. Program position and force via controller. No air compressor, no leaks, no filter maintenance. Electric gives precise mid-stroke positioning.
3. Which screw type gives longer life?
   Rolled ballscrew lasts 50,000 km travel. Ground ballscrew lasts 100,000 km. Acme leadscrew lasts 10,000 km but costs less. For high cycle applications (millions of cycles), choose ground ballscrew. Replace worn screws promptly.
4. Can an Motor-Driven Cylinder hold a vertical load?
   Yes, add a motor brake. The brake locks the screw when power cuts. Without brake, the load drops. For heavy loads (over 50 kg), add an external counterbalance. Brake engages in 20 milliseconds after power loss.
5. What IP rating suits outdoor electric cylinders?
   IP65 seals against rain and dust. IP67 allows temporary immersion. IP69K withstands high pressure washdown. For outdoor use in sun and rain, IP65 works. For food processing washdown, choose IP69K with stainless steel body.
6. Can I use a Motor-Driven Cylinder in high temperature?
   Standard cylinders operate -10°C to +60°C. High temperature versions use special grease and seals up to +120°C. For +200°C, use a cooling jacket or remote mount the motor. Magnets on encoder fail above +85°C.
7. What happens if electric cylinder overstrokes?
   Overstroke extends the rod beyond screw length. The nut tears out of the tube. Internal end stops prevent overstroke. Never remove mechanical end stops. For vertical applications, add external hard stops for safety.
8. How do I calculate Motor Driven Cylinder life?
   Life = (dynamic load capacity / actual load)^3 × rated travel life. Example: 10 kN capacity, 5 kN load, 10,000 km rating gives (10/5)^3 × 10000 = 80,000 km life. Reduce life by 50% for dirty environments.
