High Force and Fast Speed Linear Actuators
These High Force and Fast Speed Linear Actuators use a ball screw to translate the rotary motion of a brushless DC motor to linear output motion. The torque transmitted to the ball screw is amplified through a gear transmission.听Each motor is a 3-phase, multi-pole, permanent magnet, brushless DC design. Position is monitored through a linear potentiometer integrated into each of the units. The linear actuators have integrated non-jamming stops at the full extend and full-retract positions. Thermistors, heaters, or thermostats can easily be incorporated into these designs.
Key Features:
- High Speed and high force linear actuators
- High precision ball screw drive provides extra fine resolution linear movement
- Incorporates 3-phase BLDC motors
- Low backlash < 0.010 inch
- High axial stiffness
- Spherical ball rod ends
