Electric Actuators/Cylinders
Electric actuators/cylinders are mechatronic devices that convert electrical energy into high-precision linear motion. Their core function is to achieve push-pull, lift, or precision positioning control through a motor-driven screw mechanism.
1. What are the Working Principles of Electric Actuators/Cylinders?
Power Conversion
A servo/stepper motor drives a ball screw or planetary roller screw to convert rotational motion into linear displacement. The design differences between nut rotation and screw linear motion allow for adaptability to varying load requirements.
Integrated Design
A built-in battery-less absolute encoder retains position information even after a power failure, eliminating the need for zero reset upon restart, significantly improving maintenance efficiency.
Efficient Transmission
Planetary inverted roller screw technology enables a more compact design, 50% shorter than traditional electric cylinders, while simultaneously achieving high load capacity and 90% energy savings (compared to pneumatic solutions).
2. What are the Advantages of Electric Actuators/Cylinders?
Precision Control: Positioning repeatability reaches ±5μm, thrust control error ±10μm, and supports millisecond-level response and complex motion trajectory programming.
Long Life and Reliability: Over 100 million operating cycles, no seal wear issues associated with pneumatic systems.
Environmentally Friendly: No risk of hydraulic oil leakage, meeting cleanroom requirements.
3. What are the Typical Application Scenarios of Electric Actuators/Cylinders?
Industrial Automation: Robotic welding arms, SMT placement machine precision positioning
Quality Inspection: 100% product dimensional verification, switch durability testing
Specialty Equipment: Pharmaceutical filling lines, laser cutting platforms
Construction Machinery: Replace hydraulic cylinders in agricultural/construction machinery, achieving 400W-class intelligent thrust control
4. Technology Evolution Trends of Electric Actuators/Cylinders
New-generation products (such as the SMAC CBL series) integrate IoT sensors with anti-rotation structures. Their modular design reduces tolerance stacking, combining the installation compatibility of pneumatic cylinders with the intelligent advantages of servo systems.
This component will continue to drive the replacement of high-energy pneumatic/hydraulic systems, becoming the preferred solution for applications requiring force control, multi-point synchronization, or clean environments.
