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. 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.
