T3 Series Rotary Servo Actuator
Overview
T3 Series Overview
The T3 Series Rotary Servo Actuator is an advanced electromechanical actuator equipped with integrated brushless DC control electronics and contactless absolute position feedback. Its design focuses on dynamic operation in the most demanding environments, utilizing durable mechanical elements, top-tier materials, and best-in-class components.
At its core, the T3 Servo Actuator is powered by a high-power density Brushless DC (BLDC) motor, which is paired with a planetary gearhead to generate high torques in a compact package. This motor and gearhead assembly links to the servo’s output via a large spur geartrain for increased reliability.
Unlike the common industry practice of using compound spur gear trains, our unique gearing setup enhances the actuator’s capability to handle high transient loads without succumbing to structural failures.
Typical applications:
- Aerospace, defense, industrial, and maritime applications requiring:
- Dynamic and reliable rotary servo actuation in harsh environments
- High power density and compact footprint
- Structurally robust design
- Integrated BLDC control electronics with CAN, serial, and RC PWM control options
- Pressure compensated oil-filled options for submerged use to 6000+ meters
- Uncrewed Aerial Vehicles
- Swashplate and tail-rotor control
- Fixed Wing Control Surfaces
- Utility Actuation
- Uncrewed Surface Vehicles
- Rudder control
- Accessory deployment
- Subsea vehicle control surface
- Subsea Valve Actuation
Features:
- Contactless single turn position feedback of the output shaft
- Built-in brushless DC control electronics
- Control options including CAN 2.0B, RS-485 serial, or RC PWM(optically isolated)
- Feedback includes absolute position, motor phase current, temperature, bus voltage, humidity, and actuator health
- 10 VDC to 36 VDC operating voltage range (60 VDC absolute max)
- -40°C to +100°C operating temperature range
- Robust mechanical components for high peak load tolerance and reliability
- High power density with extremely dynamic motion capabilities
- D38999/20ZB35PN connector
- IP67 sealing
- Fully conductive hardcoat anodized aluminum housing for EMI/EMC protection
- 17-4PH H1100 output shaft
- continuous rotation output shaft, electronically limited travel
