The performance and compatibility of a brushless linear actuator are determined by several key technical parameters. Selecting the right actuator requires matching these specifications to your application’s demands.
- Force Output: Measured in pounds (lbs) or newtons (N), this indicates the maximum linear force the actuator can exert. Higher force ratings are essential for lifting, pushing, or holding heavy loads. For example, actuators with 100–500 lbs of force are common in industrial automation, while lighter-duty models (10–50 lbs) suit home automation tasks.
- Speed: Expressed in inches per second (in/s) or millimeters per second (mm/s), speed defines how quickly the actuator extends or retracts. Faster speeds improve cycle times in automated systems but may reduce force output due to power limitations. Typical speeds range from 0.2 in/s (low-speed precision) to over 2 in/s (high-speed applications).
- Stroke Length: This is the total linear travel distance the actuator can achieve, measured in inches or millimeters. Stroke lengths vary from short (1–2") for compact mechanisms to long (12–36") for large-scale positioning. Choose a stroke that matches your application’s movement requirements without overextending.
- Power Consumption: Measured in watts (W) or volts (V), this reflects the electrical energy required during operation. Lower power consumption improves energy efficiency and reduces heat generation. Most brushless actuators operate on 12V or 24V DC, making them compatible with standard battery systems and power supplies.
- Control Options: Brushless actuators support various control methods, including manual push-button switches, remote controls (RF or infrared), potentiometer feedback, and programmable logic controllers (PLCs). Advanced models integrate with microcontrollers (e.g., Arduino, Raspberry Pi) for automated, sensor-based operation.
- Load Capacity: The maximum weight the actuator can safely move or support without mechanical failure. Exceeding this limit can cause motor burnout, gear damage, or rod bending. Always include a safety margin (e.g., 20% below max capacity) for dynamic or shock loads.
- Voltage Rating: Specifies the operating voltage range (e.g., 12V ±10%). Operating outside this range can damage internal electronics or reduce efficiency. Use regulated power supplies to ensure stable voltage delivery, especially in sensitive environments.
- IP Rating: Ingress Protection (IP) ratings (e.g., IP54, IP66) indicate resistance to dust and water. IP65-rated actuators are dust-tight and protected against low-pressure water jets, ideal for outdoor or washdown environments. For harsh industrial settings, IP67 or higher is recommended.

Choosing the Right Brushless Linear Actuator: A Comprehensive Guide
Selecting the appropriate brushless linear actuator is essential for ensuring optimal performance, reliability, and longevity in your application. Unlike traditional brushed motors, brushless linear actuators offer improved efficiency, reduced maintenance, and longer operational life due to the absence of mechanical brushes. This guide explores the key factors to consider when choosing a brushless linear actuator, helping engineers, designers, and system integrators make informed decisions tailored to their specific needs.
Important Note: Incorrect actuator selection can lead to premature failure, inefficient operation, or safety hazards. Always verify technical specifications with the manufacturer and consider real-world operating conditions during the selection process.
Industrial Applications and Duty Cycle Requirements
The intended industrial environment plays a critical role in determining the right type of brushless linear actuator. Different industries have varying demands in terms of load, cycle frequency, and operating duration, which directly influence the required durability and thermal management of the actuator.
- High-Demand Industries: Sectors such as automotive manufacturing, aerospace assembly, and textile production often require actuators that can operate continuously under heavy loads and high duty cycles. These environments benefit from robust, high-efficiency brushless actuators designed for extended run times and minimal downtime.
- Low-Demand Applications: In contrast, environments like dental clinics, laboratory automation, or light-duty packaging systems may only require short bursts of operation—typically under 20 minutes per cycle. These applications generate less heat and experience reduced mechanical wear, making standard-duty brushless actuators more than sufficient.
- Maintenance Considerations: In continuous-operation settings, ease of inspection, serviceability, and predictive maintenance compatibility (e.g., integration with IoT monitoring) are important. Look for actuators with sealed housings, corrosion-resistant materials, and diagnostic feedback capabilities where applicable.
Expert Tip: Evaluate your application's duty cycle as a percentage (e.g., 30% duty = 3 minutes on, 7 minutes off). Choose an actuator rated for at least 10–20% higher than your calculated duty cycle to ensure thermal stability and extended lifespan.
Force Output and Load Characteristics
Matching the actuator’s force output to the load it must move is one of the most critical aspects of selection. Under-sizing leads to stalling or overheating; over-sizing increases cost and energy consumption unnecessarily.
- Static vs. Dynamic Loads:
- Static loads remain stationary once positioned (e.g., holding a door open). The required force is primarily based on weight and friction.
- Dynamic loads involve acceleration, deceleration, or movement over time (e.g., robotic arms, conveyor positioning). These require additional force to overcome inertia, increasing the total force demand.
- Friction and Mechanical Losses: Always account for friction in guides, bearings, or lead screws. A general rule is to add a 15–25% safety margin to your calculated force requirement to accommodate real-world inefficiencies.
- Peak vs. Continuous Force: Some actuators can deliver higher peak forces for short durations but must operate below their continuous rating for sustained use. Ensure your application does not exceed either limit.
| Load Type | Typical Force Range (N) | Recommended Safety Margin | Example Applications |
|---|---|---|---|
| Light (≤50 N) | 10–50 | 15% | Medical devices, small valves |
| Medium (50–200 N) | 75–250 | 20% | Automated test equipment, light robotics |
| Heavy (200–1000 N) | 250–1200 | 25% | Industrial clamping, CNC machinery |
| Very Heavy (>1000 N) | 1200+ | 30% | Aerospace testing, heavy automation |
Speed and Stroke Length Requirements
Speed and stroke length define the actuator’s range of motion and how quickly it can perform its task. These parameters must align with the operational goals of your system.
- Stroke Length: This is the total distance the actuator can extend. Choose a stroke length that matches or slightly exceeds your required travel to avoid over-extension, which can damage internal components.
- Operating Speed: Measured in mm/s or in/s, speed affects cycle time and productivity. High-speed applications (e.g., pick-and-place robots) require actuators with fast response times and efficient heat dissipation.
- Trade-offs: There is often an inverse relationship between speed and force. Higher speeds may reduce available force output due to motor and gearbox limitations. Always consult performance curves provided by the manufacturer.
- Avoid Exceeding Limits: Operating beyond the rated maximum speed or stroke can lead to mechanical failure, increased wear, or loss of positional accuracy.
Design Tip: For applications requiring both long stroke and high speed, consider using belt-driven brushless actuators instead of screw-driven types, as they typically offer faster travel speeds over longer distances.
