Rotary Servo Actuator

Transcription

1 Rotary Servo Actuator TYPICAL APPLICATIONS Unmanned air vehicles - tactical, medium long endurance and MALE / HALE vehicles - Control surfaces requiring servo actuation Target drones - surface control, speed brakes Utility actuation - throttle control, doors, spoilers Helicopter - manned or unmanned - Swash plate or flap control Model 220 FEATURES Stainless steel spur gear train 8 ball bearings Machined aluminum structure and housing Stainless steel output shaft, 1/4 inch SAE spline Consult factory for custom shafts and output arms Brushless 4 pole permanent magnet DC motor High temperature capability Contactless shaft position sensor Differential analog position feedback Full digital control (RS-485 version shipped with default address) Modifiable parameters (default parameters installed at factory) - Total electrical stroke angle - Null position - Direction orientation - Torque limit - Loss of signal - hold last position, return to zero or coast - PID constants - Dead band - Telemetry scaling - Feedforward gains GUI interface for programming and parameter modification BENEFITS Robust structural design Mechanical stops Low weight to power performance Customizable The Model 220 rotary servo actuators utilize brushless DC motors as the prime mover within our design. The available motor technology include use of neodymium magnets. The Model 220 servo is used for surface positioning, throttle control and other utility functions on several UAV and aerospace programs. These actuators are designed to operate under extreme environmental conditions and have been chosen to support new development programs, as well as program requirements. Our Model 220 is one of our most versatile actuator designs primarily due to the ease of integration with several interface technologies. This baseline unit is very well suited for a variety of applications and is not limited to UAV and target programs.
